Although the offshore sailing season is drawing to an end; it is never too early to look to your 2020 sailing season. Offshore racing, both crewed and shorthanded, is one of the biggest growth areas of sailing domestically and internationally.

UK Sailmaker's Yannick Lemonnier is one of the most experienced offshore racers in the country. With over 10 years of experience and more than 80,000 miles under his belt, mostly solo and double-handed, he is full of offshore sailing knowledge. Here gives us some top tips to bring into your 2020 offshore sailing season.

The Mainsail

The main is the one sail that we always have up, no matter the point of sail. Trimming and managing it is crucial to success – so how can you make life a bit easier?

A reefed mainsailA reefed mainsail

  1. Stitch all your battens. This is as simple as using a hand sewing needle to put a quick stitch at the extremity of each batten pocket. This fully secures your battens no matter what weather you encounter. The consequences of losing battens can be dramatic for the integrity of the sail and its performance.
  2. Reefing. Tie the bottom part of your mainsail with small diameter bungee and plastic clips instead of solid rope. Releasing your reef with one tie remaining can seriously damage your sail – and can easily happen when tired or on a dark night.
  3. Glow-in-the-dark draft stripes. These make trimming your sails at night so easy. Each stripe should be marked at the 50% chord length to give a good shape reference. These stripes can be retrofitted to older sails (depending on their age). 
  4. Reef assistant. This is a great option for regular offshore racers. Basically it is an additional pennant set just above your reefing eye at the luff end of your mainsail. It gives you a solid anchor to either pull your reef towards its hook or release pressure to unhook the reef in strong winds.
  5. Tie up the sail, not the boom! This is one we see a lot. When lashing up your reefed sail to not tie it around the boom. Instead, lash it around itself. You should have a tie going from the leeward side, around the loose sail between itself and the boom, and tied securely on the windward side with an easy to release knot.

When sailing upwind or tight reaching, depending on your inventory, you will be using your headsails – quite likely multiple headsails. Keeping on top of them and practising crew manoeuvres with them is critical to a successful offshore race.

  1. Stitch all your battens. This is the same as with your mainsail – but even more so as your headsails are more exposed to flapping as they are hoisted and dropped. Securing the battens is essential. This is a really quick and basic job which can prevent a lot of trouble down the line.
  2. Peels and tack peels. This manoeuvre is a must – and it is not complicated with proper training and the correct setup. Having a second attachment either side of the tack attachment point is recommended. And make sure to keep a close eye on your halyard to ensure no wraps occur. I would recommend to always drop the sail on the inside as dropping outside is risky and can lead to you losing your sail!
  3. Glow-in-the-dark draft stripes. As with the mainsail, these make setting halyard tension, car positions, sheet tension etc much more efficient at night. Glow tell tails on the luff make steering and trimming a doddle on those dark nights. 
  4. Spare sheet and block. This is to clip onto the outside rail, or purpose installed padeye, to outhaul the headsail on a reach. This is essential. Every time your clew moves up and down you are losing power. A well-positioned outboard lead padeye and the hardware to go with it makes a huge difference to off the breeze speed.
  5. Know your inventory. Knowing your sails is critical regarding wind range and angles. Where is your limit between J2 and J3? Between an outhauled genoa and code zero? The only answer is practice and recording. Experiment with different setups and take note of what works, and more importantly, what doesn’t!

We all love sailing downwind when offshore. It can be fast and fun. It can certainly be a lot more comfortable than beating into a gale! But it brings its own challenges.

SpinStopsOnDragonTackSpinnaker stops on sail tack

  1. Choose your colour carefully. White spinnakers are difficult to trim at night. They are like a ghost. I would recommend a dark colour to get more contrast – I also find white harder on your eyes in bright sunshine.
  2. Velcro for control. Heavy spinnakers should be equipped with Velcro banding to keep them deflated while hoisting. They allow you to hoist the sail and stabilize the boat, then pop the sail out when everything is ready.
  3. Repair early. Gets lots of 100mm insignia tape (stick-back dacron) to fix small tears that can become a bigger problem. This tape can also fix other sails along with a bottle of acetone (nail varnish remover) to remove salt and dry the sail surface.
  4. Inspect for chafe. Don’t worry, we’re talking about your halyards! If on a long spinnaker run chafe can become a real issue. Covers can wear on sheaves or deflectors overnight. Ease the halyard a foot and check with the binoculars for visible signs of damage. If you can see it with binoculars it will be a bigger problem sooner rather than later.
  5. Peeling practice. Peeling spinnakers is actually easier than peeling headsails. The most crucial element is good halyard management. Have a spare peeling sheet, with snap shackle, ready and accessible. Think and talk the manoeuvre through – and, as always, practice!

Storm Sails

Whether we like to admit it or not, there is a tendency to see storm sails as a box-ticking exercise. Not many sailors have a clue how to rig them, never mind use them properly! 

StormSailsWave2Storm sails

  1. Firstly they should be stored in a separate dry bag. Piston hanks tend to corrode in an offshore environment unless used regularly – they should be replaced with soft shackles.
  2. The storm jib should have a tack strop of a set length. This should position the sail at a height that lines the clew up nicely with your jib car position.
  3. The trysail should ideally be on a separate track. It should be rigged with spinnaker sheets lead inside the guard rails – as we discovered after training in just under 50 knots!


A huge part of offshore racing is managing your energy. By making the boat as easy to sail as possible, and removing any potential issues before they occur, you can put 100% of your energy into making the boat go fast. Plan, practice, and enjoy your offshore adventures

Published in UK Sailmakers Ireland

In early 2019 the news broke that there was a new “WOW” on the way to Ireland from Lisbon. George Sisk had added a new XP44 to his line of successful racing yachts named “WOW”. Barry Hayes reports on the role of UK Sailmakers Ireland.

Following a competitive bid process; the UK Sailmakers Ireland team was chosen as their sailmaker for the project. We hit the ground running and, having a strong working relationship from the previous WOW campaign, we were able to work closely with George and his team to get as much info about the new boat as possible before her arrival.

Research and Requirements

The first phase of any project is to research the boat you are working with, its behaviour and performance characteristics, and gather the requirements of the owner. This gives us a clear path toward success.

Performance Research

The XP44 is a regular competitor in events throughout Europe, both inshore and offshore. We gathered key IRC data and past race results to give us a picture of where the boat performed best, and what her disadvantages were. We found that reaching, sail handling, and her IRC handicap were key issues which needed to be addressed.
With our polar performance data from other XP44s in hand; we gathered further data from other UK Sailmakers lofts in our network who have raced and made sails for the XP44, and what their overall impression of the boat was. Digesting this experience, and cross-referencing it with our performance analysis data, allowed us to refine our design and optimisation approach for the WOW project.

With a good understanding of the performance characteristics of the new boat, we could focus on compiling the key requirements for the campaign. A major part of this is the events the boat would compete in, who she would be racing, and the prevailing conditions she would be racing in.

These requirements then steer the sail wardrobe development and design as well as the IRC optimisation process.

The main focus for the WOW campaign for 2019 was coastal racing, major offshores, and local DBSC racing. This put usability and straight-line speed at the top of the priority list. It also meant that a significant amount of the off-the-wind sailing the boat would be doing would be tight or broad-reaching as opposed to the deep downwind sailing you would get if the boat was solely focused on inshore windward-leeward course racing.

From our performance analysis, we knew that reaching was one of the boats main weaknesses. This is due to the balance of the boat. When reaching the powerful mainsail needs to be offset by a strong sail force forward of the mast. If this is not done then the boat has a tendency to spin out to windward in gusts rather than accelerating – causing the helm to constantly fight the boat with the rudder. We will talk about our solution to this issue in our sail specification and design later in the article.
We concluded our requirements gather phase with the following initial requirements:

  • Optimize performance for light/medium conditions
  • Balance helm off the wind
  • Maximize usability and simplicity of the sail wardrobe
  • Ensure power is controlled in heavy airs downwind


Early in our discussions, it was decided to fit a longer bowsprit to the XP44. This additional length would give us a better aspect ratio for the spinnaker designs (STL:SPL). It also gave us more option in the forward sailplan of the boat for keeping the helm in balance, discussed further below.

IRC Optimisation

Graham Curran focused on the IRC rating optimisation process. We knew that the boat performed well in the 8-10 knots wind range based on the polars and weight/wetted surface numbers for the boat. Our goal was to maximize this performance range, achieving the best power to weight ratio possible, while optimising the IRC rating for the required sail area.

A major part of this optimisation was the HSA (headsail area). We shortened the LL of the headsails (luff length) as much as possible while maintaining area by pushing out the LP and girths to the maximum we could fit in the foretriangle. This gives maximum benefit of sail area vs IRC penalty while also maximizing the inhauling effect of the jib leech.
This takes a lot of work and several trial certificates to perfect but we had already done a lot of work on the subject with our J109 development the previous winter. With accurate measurements, 3D modelling, and IRC certificates; we knew exactly what we were looking to achieve performance wise vs the final IRC rating.

Sail Wardrobe and Design

In conjunction with the IRC optimisation, Barry Hayes began specifying and designing the sail plan. The first phase of this is accurately modelling the yacht and her sail plan in our 3D design software. We then refine this model throughout the design and optimisation process.

Sailpack 3XP44 modelled in real-time 3D. This is the base model for the design phase

Reaching Performance

Our performance data clearly showed that there was an issue with the reaching performance of the boat. We had an indication that this was due to the balance of the boat so our first step was to assess the lead of the boat.

MH0MH0 (masthead code zero)

‘Lead’ is the distance between the centre of effort of the sail plan, usually the Working Sail Area which is the main and fore triangle (CE); and the Centre of Lateral Plane of the hull/foils, (CLP). Both the CE and CLP are approximate positions for the centres of pressure for the sail area and the hull underbody and only really used by yacht designers at the design stages to ensure that the keel and rig positions are well balanced.

This assessment reinforced our understanding of the problem; and what our solution would be.

It was clear that we needed to have a MH0 (masthead code zero) in the inventory. This large code zero helps by pushing the bow down, counteracting the mainsail, and keeping the boat in balance on a reach. The MH0 needs to be a little smaller than maximum to ease sail handling and for use while tight reaching/near upwind work in light airs.

Throughout this design process it became clear there was another performance window to be exploited.

The MH0 is simply too much sail area for tight reaching between 50-70° apparent, depending on the wind speed. This would put the boat back on a full mainsail and headsail, with imbalance remerging as a result. The solution to this issue, and a clear performance gain, was a Flying Jib.

This sail is the same area as the maximum IRC headsail area because, as the name suggests, it measures as a headsail rather than a spinnaker like the code zero. The flying jib is set of the end of WOW’s extended bowsprit, giving greater separation from the forestay and allowing a ‘double-headed’ headsail setup with the J3 set on the forestay foil, and the flying jib outside it. It is also a furling sail – functioning like a furling code zero.

flying JibFlying Jib

We virtually analysed the flying jib at the 50-70° angles and found a speed increase of approximately 1.2 knots while also keeping the boat balanced.

As the boat comes off the wind she will swap back to the larger MH0. Filling this gap with the flying jib allowed the MH0 to be increased in size, making it more effective downwind. Combining the two sails in the inventory made each sail better than either could be on their own. WOW now had a full effective reaching range from 50° AWA with her flying jib to 130° AWA with the MH0.

Upwind Package

Given the target HSA from our IRC optimisation; Barry moved on to the design of the upwind sail inventory. The designs were based on the polar performance data from the current sail plan which were then refined to allow additional inhauling with a twisted headsail design – allowing greater pointing without sacrificing speed – while maintaining our target IRC rating.

UpwindUpwind sailing

Handling of the mainsail was a major point of discussion within the team – the mainsail would have to function well both inshore and offshore with usability being paramount. Reef heights, luff tape or slides, full battens or short – all these decisions were influenced by this discussion with the team. We worked off the fact that other XP44s use a luff tape on their mainsail – this proved to be a difficult setup with the external mast track. We spoke with our UK Sailmakers partners who advised us on ideal luff setup and effective reef heights from their experience.

This additional information simplified the decision for the team. The mainsail was specified with two reefs, Antal luff sliders, and short leech battens.

To further optimise the IRC rating we put a small fathead on the mainsail and reduced her P measurement – resulting in a favourable aspect ratio.

Downwind Spinnaker Package

The main concern for the team was boat handling downwind in heavy airs. The XP44 has a bit of a reputation for being a handful when the breeze is up as she doesn’t plane. Solving this issue and getting the best performance from the SPA (spinnaker area) was the last critical step in this design phase.

From running trial certs we found that 190m2 produced the best power to weight ratio with a favourable rating. We worked from this number to determine the size of her working spinnakers.

The A1.5 is a sail made for light air performance. It is designed to work at tight VMG angles in light airs and then rotated once the tack is eased in building pressure. This would be the workhorse of the boat on Dublin Bay.

DownwindDownwind sailing

As the boat would be rated with three spinnakers the last slot was reserved for a heavy air spinnaker. We design a hybrid A3/A4 sail which we have worked with extensively in the past. It is designed to be an A3 (medium air reacher) when flown from the masthead halyard but doubles as an A4 (heavy runner) when flown from the fractional halyard. The smaller area required for an A3 tied in well with our power management requirement for the heavier air A4. The logic for using the fractional halyard for the A4 is purely for boat handling. The boat does not need the additional power in heavy airs and bringing the hoist down makes the boat more stable and easier to handle.

Sail Testing and Performance Analysis

Once WOW arrived in Dun Laoghaire she was immediately weighed and measured for her new IRC certificate – including the new extended bowsprit.

At this stage, the sails were in production and were soon delivered to the boat to be fitted and tested with Barry and Graham.

The code zero was to fly on a padeye on the bow of the boat, just in front of the forestay, while the flying jib is flown from the end of the bowsprit. Load testing these points, the halyards, and the hardware that holds them is extremely important before ever leaving the dock. It is the safest way to load the boat and give the crew the confidence to take the gear offshore without any doubts in their mind. After several full load tests and adjustments of the bobstay, it was time to go sailing.

BobstayAdjusting bobstay tension is when teamwork really shines

One the water we set up all the sails and optimised deck layouts, the run of furling lines, sheets, halyards etc. We then assessed the boats upwind performance by fully loading the Uni-Titanium upwind sails and confirming the rig’s bend characteristics.

Team Approach to Development and Results

We worked closely with the WOW team to bring their concept into reality – it was now time for the new XP44 to go racing. Straight away she was top of the DBSC results pages winning her first Saturday race on the bay. She finishes up her 2019 DBSC season winning the overall Thursday league and, at the time of writing, leading the Overall Saturday series.

Her most notable performance of 2019 was at Kinsale’s Sovereigns cup where she went bow to bow, wave for wave with her bigger sister, the XP50 “Freya”. It was amazing sightseeing these yachts battle off the coast of Cork for the week – with WOW triumphing with three wins from three races.


“As soon as Barry and Graham of UK Sailmakers heard about George’s new Xp 44 WOW coming to the bay, they got to work analysing the best sail package for the boat based on what we intended to do with her. Once the new sails arrived, they were available to set them up and work with us to achieve the best outcome from them. Since then, nothing has been too much for them. The UK team has been available at a moment’s notice to provide solutions to all sorts of problems – from damaged sails to broken parts and even the design and supply of a cockpit tent, as well as the set up and trim of the new sails. In my opinion, the collaboration between WOW and UK Sailmakers has been instrumental in the success of our first season with the Xp 44 WOW. We are looking forward to continuing – and growing – our relationship with the UK Sailmakers Ireland team in 2020 and into the future.” – Gavin Stillman, Boat Captain

We all know sailing fast in a straight line is very important. That is where, as sailmakers, our products shine and our technical background can be leveraged for your benefit writes Graham Curran. But races are won and lost at the corners. You can be the fastest boat on the water but if your critical manoeuvres are not dialled in then one bad hoist or drop could have your advantage erased immediately.

Let’s take a look at look at leeward mark rounding techniques and present some top tips for perfecting your manoeuvres. With that said; there is a lot going on at the leeward mark with a lot of elements in play, including conditions, spinnaker setup, boat size, course layouts etc, so this list is no means exhaustive, but if you can work on these general points then you will be many steps closer to that elusive perfect leeward mark rounding.

We are going to break our tips into light air tips and heavy air tips. As we will see, the wind speed plays a major role in how you should approach your drops.

Light Airs

  1. Keep your spinnaker flying as long as possible. In light airs, it is easy to be over-cautious with your spinnaker drops – dropping the spinnaker early and slowing boat speed significantly. We need to keep the spinnaker driving the boat for as long as possible to get us to the leeward mark at maximum speed. As the wind is light we will have plenty of time to get the sail down as we turn around the mark.
  2. Partially hoist your jib but not so much that it affects the spinnaker. Getting the jib up is good, you’re certainly going to need it, but timing is everything. When the jib is in the air it immediately begins effecting the airflow onto and across the spinnaker with the potential to collapse it early – we’ve all been there and it isn’t fast. Half hoist the jib so the first couple of battens are clear of the guard rails – this keeps the spinnaker clear while also ensuring there are no issues with the jib hoist itself. Once the drop (and the mark) are imminent – hoist the jib fully. Make sure the jib sheet is loose. This will help keep the kite going to the very last second. When rounding trim the jib constantly as the boat turns – do not ram it in early to save yourself some grinding on the other side!
  3. Manage your crew weight. I cannot stress this point enough – especially in light airs. Once the spinnaker is down and not in the water – sit down. Get to leeward if the conditions require it and stop moving. The best drops can be ruined by a bouncy crew on the deck. At this point, it is critical for the boat to build speed and exit the mark as fast as possible. Generally, at this point we are trying to escape the fleet or get to the favoured side – boat speed is of utmost importance. An over-eager bow crew preparing for a windward mark that is 40 minutes away is simply not helpful. Sit down, settle, let the boat accelerate, and then pick your time to do your jobs.
  4. Keep your trimmer focused. There is a lot going on at the leeward mark. Boats approaching, likely plenty of shouting, sails going up and down. It is critical for your spinnaker trimmer to stay 100% focused at this point. As the jib goes up the spinnaker behaviour will change and trim will need to be adjusted to keep it drawing. Active trimming here is worth its weight in gold. As the old saying goes – “if in doubt, leave it out”.
  5. Plan ahead to optimize your crew work. Ideally you want to drop the spinnaker on the side which it will hoisted at the next mark. This is not always possible but it is what we should be aiming for. This results in less work for your bow team and pit crew, which means less running of gear, more weight effectively placed for longer. Know your course and know what drop option will suit you best – then try to make it happen.

Spinnaker Drop 1349A Spinnaker drop at a leeward mark in a Beneteau 211 Photo: Afloat

Heavy Airs

  1. 1. Manage the spinnaker halyard. It should go without saying that the spinnaker halyard should be flaked and ready to run. The pit crew, when the drop is called, should smoke ¼ of the spinnaker halyard to instantly depower the sail and allow the bow crew to get a good handful of the sail into the boat. Once this is done the halyard should then be eased gradually to ensure the sail does not end up in the water. The faster this first portion of the halyard is blown the better – you want to shock the spinnaker into submission!
  2. Get the pole away early. In moderate/heavy airs there is plenty of pressure in the spinnaker to keep it set. The pole can be cleared early to make the drop much cleaner and give you more options for manoeuvring during and after the drop. If flying a symmetric spinnaker use a crew member to “human guy” the spinnaker to help the trimmer maintain control. If flying an asymmetric spinnaker “clearing the pole” is as simple as un-cleating the pole outhaul rope before the drop so that when the spinnaker unloads and is being recovered the pole is automatically pulled in – just keep an eye on your tackline so it doesn’t go under the bow!
  3. Get hiking! Similar to light airs, crew weight management is crucial. Get the weight on the rail as soon as possible. If the kite isn’t at risk of going in the water and the boat is clear to tack then your weight should be hiking – not tidying. There is an entire windward leg to prepare for the next hoist or coil your sheets. Hike first, housekeep later.
  4. Drop early and gain. Much the opposite of the above – push to your limits, not beyond them. An early drop doesn’t hurt boat speed significantly in a heavy air situation – having the spinnaker still in the air as your turn upwind however very much does. Get the spinnaker down early and safely and get the crew to where they need to be as you turn the corner.
  5. Avoid a leeward drop. In heavy airs, leeward drops are just asking for trouble. Sometimes it is unavoidable but if at all possible use any other option.

Put in the time

UK Sails 3792

“Time on the water is king” – there is no denying this. The more you and your crew sails together the better your manoeuvres will be. And its time well worth spending. Put in the practice before racing begins and give yourselves time to learn.

On top of this – know your limits. It is tough, when in the heat of battle, to take a step back and assess the situation. It is crucial to know what you are capable of as a crew. This will allow you to push your drops to the limit, but not beyond them, and by doing so you will gradually improve as the manoeuvre becomes smoother.

Get out on the water and make the most of the upcoming Autumn Series! See you on the water!

Olympic sailor Mark Mansfield who is an agent for UK Sailmakers Ireland offers his five top tips for those looking at buying new sails this year.

1. Correct Size Sails

Make sure the new sails are the correct size. IRC rule changes are happening all the time and good advantages can be had from optimising the sail sizing, sometimes by just a small amount. Make sure you get advice from your sailmakers about what is best. We had one Class One boat this year that ended up with the same size sails as before but dropped two points by changing the shape of their sails a small amount.

2. Seasonal Discounts

Make sure you take advantage of any discounts that might be available. Autumn is traditionally a quiet time for production facilities and so discounts are offered for orders at that time. At UK Sailmakers, we have just introduced a new discount arrangement. More details here

3. Sailmaker's Knowledge

Make the best use of your Sailmakers. People working with sailmakers have a wealth of knowledge about what makes boats go fast. Whether it is helping you with your rating optimisation, helping you tune your rig or other areas, make use of them. Sometimes this can be added as an included extra in a sails purchase deal.

4.  Loft Facilities

Ensure the sailmakers you are thinking of has a proper loft to be able to service and adjust your sails. Ordering from a sailmaker with no proper loft facilities means adjustments or repairs are extremely difficult to organise. We recently had a customer who twisted his Code 0 cable and was unable to untwist it himself. It went down to our loft in Crosshaven where the 17-metre sail was hung up, untangled and refitted. This would be very difficult to achieve without proper facilities.

5. Sails to Suit Requirements

Make sure you are being quoted the material in the sails that suit your requirements and not some lower-tech and cheaper material that looks fancy but actually will stretch very quickly and not last long. For racing boats over 30 foot or even a bit smaller, the go-to material for quite a few years for low stretch is Carbon. The problem with not having Carbon in high load sails is if you exceed their normal wind range, they will eventually stretch, and once that has happened, you end up with turned in leeches and baggy sails. They will not last competitively for the same number of years as Carbon-reinforced sails.

So, Why Carbon?

A quick history lesson on sail materials.

Up to the ’70s, nearly all sails were made from Dacron (Polyester) and were 'crosscut'. Fairly cheap, stretchy material, but lasted a long time.

In the late ’70s, new materials such as Mylar emerged with much less stretch and were used for quite a few years.

In the early ’80s, Kevlar became the go-to material. Originally used for bulletproof vests, it had good stretch resistance but was more expensive. The first Kevlar sail I ever sailed with was on Moonduster in 1981, her first year, when she did the Admiral's cup. Kevlar sails in those days were still crosscut.

In about 1982, tri-radial sails, using a combination of Mylar in the low stretch areas and Kevlar in the high stretch areas(such as the leech) changed the way sails were made forever. Kevlar, however, has low UV protection and stretches after a lot of flogging and wear.

In the early 2000s, Carbon was introduced to sails and this was another game-changer. Much less resistant to UV damage and significantly less stretch. It has become the option of choice for the racing community. It is more expensive, however, which is why some sailmakers when in a competitive situation, sell sails without Carbon.

At UK Sailmakers, our Race sails (X drive Carbon, Titanium and Uni Titanium) are all Carbon-reinforced sails. The latter two options are moulded sails.

The graph below shows the strength differences 


If you are buying new sails, here is what you should be looking at:

  • Fully Cruising - Dacron is fine
  • Cruising and occasional races on Echo - Dacron is still fine
  • Racing mainly and occasional cruising - Carbon-reinforced sails such as UK Sailmakers 'X drive Carbon'
  • Racing mainly, club level - Carbon-reinforced sails such as 'X drive Carbon'

Olympic keelboat helmsman Mark Mansfield of UK Sailmakers Ireland discusses headsail options 

If you go back 20 years, or even 15, most designs coming out had large overlapping (headsail goes outside the shrouds) headsails to give them power in the light airs. Many of these designs were fairly heavy and needed the extra sail. However some were built lightly and even though designed with Overlapping headsails, are able to convert very successfully to non-overlapping (headsail is forward of the shrouds and spreaders).

It was the likes of designers John Corby, Jason Ker and Mark Mills who highlighted in their designs that non overlapping was all that was needed, even in light airs, as long as the boats were not too heavy and the masts were placed well back in the boat to allow a generous foredeck size, which in turn allowed a fairly large Headsail to be set forward of the spreaders.

What designs work well as non-overlapping?

There are a number of factors to be taken into account when looking at a boat to see if non-overlapping is worth doing. Here are some—

  • Does the Sail area/Displacement ratio show that this design can work well in light airs with a non-overlapper?
  • Was the boat designed first day with a fairly large foretriangle—with the mast well aft?
  • Does the design have a low wetted surface area, as in light airs, a low wetted surface area helps to survive with a smaller headsail?

What designs do we know of that can be converted?

Likely the most successful design that is able to be adapted, without any work, from Overlapping to non-overlapping Headsails, is the J109. These boats were designed originally in the US for lightish air conditions and had big 135% headsails. However, they were also built quite light (about 5000Kgs) and had quite a large foredeck (j-- about 4 metres). As IRC penalizes sail heavily, it was found about 12 years ago that to just change from a 42 sq metre headsail to a 31 sq metre, non-overlapping headsail saved about 15 points in rating. It was also found that in only under about 9 knots of wind would the smaller sail boat be slower. As a result, most J109’s now rated on IRC, are with the smaller headsails.

If you take a similar weight boat, like an Elan 333, it doesn’t work well with them, as their foredeck measurement is only about 3.6 m. In addition, their forestay is not that high, so even with an overlapping headsail, they only have about 32 sq metres of Headsail. If they were to go non-overlapping, they would need to come down to circa 22 sq metres and that would make them very vulnerable in light airs.

What other designs are suitable for conversion?

At UK Sailmakers this year, we have assisted in the conversion on many designs from Overlapping to non-overlapping. Normally this happens when the overlapping headsails get to the end of their life and the option to move to non-overlapping is suggested. The benefits of making the move, if it works for the boat, are:

  • Less expensive headsails
  • Easier and faster to crew—Less sail to winch in after every tack. Easier to Hoist and drop.
  • more competitive on IRC.
  • The Boat normally points higher as the smaller headsail is set further inboard.
  • Boat is more manoeuvrable with the smaller sail

Designs we have done this year are:

  • X362 sport—Similar weight and sail area as a J109
  • Beneteau 44.7. We converted both Lively Lady and White Tiger this year to non-overlapping.
  • Starflash Quarter tonner—Superhero—Won Icras class 4 this year
  • Formula 28
  • Beneteau 34.7

In the case of the two Beneteau 44.7’s this decision was made easier by seeing how a similar design had done in the Solent a few years ago, including winning the RORC overall points championship. When we look at a possible conversion boat, we see how similar conversions may have worked on similar designs, before making the decision with the client.

The Beneteau 44.7’s and Beneteau 34.7 all use Roller headsails, so conversion can happen both with Roller headsails boats as well as boats with Headfoils

Large builders like J boats, X yachts, Beneteau and others have been building lightish displacement cruiser racers for quite a few years. Their older designs are very often suitable for conversion. Their newer designs already are all non-overlapping.

Quarter tonners and Half tonners benefit from conversion, but only when their masts and keels have been moved aft to allow a larger non-overlapping headsail to be set. This can be an expensive operation. In larger cruiser racers this is rarely an alternative.

In nearly all cases when a boat converts from overlapping to non-overlapping, an inhauler needs to be fitted to pull the headsail clew further inboard. This allows the new non-overlapping headsails to be designed with fullness in the sail, and also allows the sail to be flattened easily. Normally the new non-overlapping headsail would be designed to go from 0 to about 16/18 Knots. Then the boats existing no 3 can be used. In some cases, owners will ask for two headsails to fill this 0-17 knot range and a full light air sail (J1) will bring the boat up to 10/11 knots, then a J2 will be used from about 12 to 17 knots.

Maybe this is twice the cost, but bear in mind that the two sails will likely have only half the use, and so will last twice as long.

Do you need to change to non-overlapping?

As discussed above, some designs just don’t work as a non-overlapper. If you have a design that would work as a non-overlapper, you can still opt to sail, at a higher rating, with the big overlapping sail. I recently competed in the J109 UK Nationals in Medium to strong winds. In the J109 class over there, they allow both non-overlapping setups, and overlapping setups to be used, with no difference in rating. It's just first across the line. Problem is, if you choose the big sails, you must stay with them for the whole regatta. Likewise, if you choose the smaller non-overlapping sails, you must stay with them.

In our case, we only had the Overlapping headsails and in a medium to strong wind regatta, we had to carry the big overlapping headsails right up to 20 knots. What we learned from this, is if you have the Rig correct, you can still compete very well, even in conditions that were regarded as too much wind for the sails. The trick is to try and keep the forestay straight by tightening the Lowers and intermediate shrouds a lot. This allows you to apply extra backstay to keep the headstay tight. In conditions that should have suited the Non Overlapping boats, we ended up winning the Nationals by 10 points. Lesson learned was that non-overlapping isn’t always necessary, but bear in mind this was not under IRC. If it was, it might have been a different story.

Can a boat be assessed to see if it is suitable for conversion?

At UK Sailmakers Ireland, we have a number of very experienced sailors and Sail designers that can look at individual designs and give a very good opinion on whether it is worth doing or not. If an owner wanted, we also have the services of an expert Naval Architect Consultant who can assist, on a fee basis, and do an individual report on a boat.

So, whether you are racing at the top end of ICRAs or sailing for fun in club racing, it is always best to get the advice of your sailmaker and UK sailmakers Ireland have been around helping clients for 50 years. Give us a call or an email if you want any help or advice (contact details below)

Barry Hayes, Director of UK Sailmakers Ireland highlights some recent successes for Boats flying UK Sailmakers sails from Ireland, both around the country and in the Solent

Following on from considerable inshore successes for UK Sailmakers Ireland (three IRC class winners at ICRAs, four IRC class winners at the Sovereign's Cup in Kinsale) UK Sails are thrilled with the results being achieved in the uber-competitive offshore and coastal racing around Ireland and elsewhere.

Last weekend, Jackknife, the J125 owned by Andrew Hall from Pwllheli Sailing Club, was the overall winner of the Dun Laoghaire to Pwllheli ISORA race and now holds a 34-point lead in the overall season's ISORA standings from Paul O'Higgins' JPK 10.80 from the Royal Irish Yacht Club. Jackknife has a full UK Sails Inventory, including specialist offshore sails such as a flying Jib and a Code 0.

"Twist" is one of the many buzzwords in sailing. We might know what it is and when it's needed – and when it’s not – but why do we need twist in the first place? And what effects does it have in our decision making process all around the race course? Graham Curran of UK Sailmakers Ireland takes us through his thoughts on sail twist.

Walking through Dublin Airport arrivals, fresh off the plane from Southampton after the weekends’ RORC Channel Race, I was going through the events of the previous day and night. I was sailing aboard Chris Frost’s Swan 36 “Finola” in preparation for our Fastnet Race starting next weekend.

We crossed the line at 0800 on Sunday morning after 23 hours of racing – finishing 2nd in our class about four minutes behind the winner. As is usually the chase when you finish second; I was going through the race in my head to find where we could have gained those four minutes of corrected time. There were several occasions where there were gains to be had or losses that could have been avoided, but there is one in particular which we found interesting – and which leads into the topic of this article.

Critical Sail Selection

At 0200 on Sunday morning we were in the last 40 mile stretch of our course – approaching the Owers turning mark before heading back for the Solent. We had been flying our S2 spinnaker (symmetric runner) since the start of this long downwind leg in 12-15 knots of breeze. As we rounded St Catherine’s point and made our way to Owers the breeze began to steadily clock right; making our sailing angle tighter and tighter.

Eventually, we ended up tight reaching with our pole just off the forestay with our log reading around 6.8 – 7.5 knots with a significant load on the helm and lots of active mainsheet trimming needed to keep the boat on her feet. Something needed to change. Finola’s set up left us with three options – continue as we were, unfurl our 145% overlapping genoa and set up on an outboard lead, or swap to our Code Zero. There were several things to consider when making this decision including the late hour, the breeze, sail sizes, effective ranges etc.

"Something needed to change"

Our decision was to drop the spinnaker and unfurl our genoa and set up an outboard lead for effective sheeting, and then consider launching our Code Zero after evaluating the situation. As always the lads on the bow played a blinder; the drop and swap was done seamlessly without issue. We gave ourselves ten minutes to settle and evaluate and found the boat was much easier to handle with little or no undue pressure on the helm, but our speed was down to 6.0 knots – time to try the Code Zero. After a short period of bow work and cockpit setup we had the Code Zero flying and our genoa furled up once again. Settle and evaluate. Finola was now cruising along at 6.8 to 7.5 knots once again, as we were with our S2 spinnaker up, but the difference in her behaviour was dramatic. No significant heel and a wonderfully balanced helm. A valuable lesson learned (several lessons in fact) – but what does all this have to do with twist you ask? Let me explain.

What is Twist?

Twist in its raw form is a difference in your sails’ angle of incidence when measured at points of increasing height up your sail. Simply put; it is the amount the sail “twists open” at the top when compared to the lower sections.

"We increase twist in light winds, we take it out as the wind increases"

Most of us think of twist in the context of sailing upwind with a mainsail and jib/genoa. We increase twist in light winds, we take it out as the wind increases. This has a lot to do with how the wind is behaving at different heights. Wind that is closer to the surface is slowed due to friction and, as a result, its angle is changed. Wind which is higher (farther from the surface) does not experience the same amount of friction, so its angle is not changed as much. As such we have varying wind angles at increasing heights so we, in turn, need to twist our sails to make sure our sail is trimmed correctly to the changing wind angles at the different heights. This is particularly important at low wind speeds where the wind angle difference is significant. As the wind speed increases the surface friction has less of an effect on the wind angle – there ends up being little difference in angle between the top and bottom of your mast (depending on your mast height of course) – so less twist is needed to trim your sail correctly.

The above applies to sailing upwind – and we are familiar with it as a sail trim fundamental – but there is another more intrinsic way of looking at twist which applies to all modes of sailing. In essence twist gives us the ability to control the lift and drag produced by our sails.

The Lift and Drag Compromise

Life is all about compromise. Sailing is no different. Where there is lift, there is drag. Our goal as sailors is to maximise and harness lift while minimizing resulting drag. Lift gives us the power to move forward, above and below the water. Drag is what slows us down, usually manifesting itself as heel and stall.

So lift and drag are intrinsically linked – they go hand in hand. In some cases drag is a good thing. There is a tipping point where having a relatively high amount of drag is good as its corresponding lift is more beneficial to the entire sail plan. But for the vast majority of our sailing drag is bad, lift is good.

So how does this tie in with Sunday morning’s lesson aboard Finola?

Drag Bad, Lift Good

Let’s keep it simple, primal as it were – down to caveman style “drag bad … lift good”. When we were reaching with our S2 spinnaker we had plenty of lift. The boat was moving through the water at hull speed or above it. We had all the lift we needed. The problem was that the spinnaker was causing too much drag, which manifested itself as heeling moment. To keep the boat on her toes we need to use a lot of rudder and ease the mainsheet. More rudder means more drag below the waterline – slowing the boat as a result. All of this making the crew work much harder than is needed at 2am in the morning.

This is not the spinnaker’s fault. A running spinnaker will simply, by design, not reach effectively. It has a deep profile with wide shoulders. Great for running downwind. Not so great when sheeted in hard while reaching. The shoulders close in behind the mainsail, hook, and stall, causing drag and heeling the boat.

So we opt for the genoa instead of instead – dramatically less drag as the sail can be trimmed perfectly for the angle of sailing with the ability to get the twist correct without causing any hook (drag) in the leech – but the sail did not produce enough lift to keep us at the speeds we were doing with the spinnaker. This is mainly due to the drop in sail area, the genoa; even at 145% overlap, is less than half the size of the spinnaker. So on the whole it was more effective having the spinnaker up, despite its drag downsides.

Enter the Code Zero. At 58sqm it splits the difference in size between the spinnaker and genoa but, far more crucially, it is designed with much more twist in the leech. When we trimmed our Code Zero on the log instantly jumped back to the 7ish knots we were looking for – but without the excessive heel we had with the spinnaker. A Code Zero is designed to sail with a lot more twist in its leech when compares to a running spinnaker. Although the Code Zero will produce less lift, mostly because it has a smaller sail area, it will also produce less drag than a hooked stalling spinnaker. The Code Zero produces more net lift, despite its smaller size, and it all comes down to what? – twist.

Conclusion(s) about twist

To be very clear, this is not a pump piece for Code Zeros. They are great sails and they have their place, and are much more versatile than they are given credit for, but that is not the point here.

We used twist to reduce drag and increase lift. We did it in the form of a sail change. But this is not always the case. Next time you’re sailing and you’re fighting the helm, or your boat speed is slow and you don’t know why, or you need to accelerate to avoid being rolled – consider the lift and drag relationship and use twist to tip the balance in your favour.
Before I sign off I want to share two more quick notes on this particular situation.

Firstly – we used the Channel Race explicitly for the purposes of learning ahead of the Fastnet. I would certainly consider not swapping to the Code Zero straight away as a mistake in the context of the Channel Race alone. It may not have cost us the four minutes needed to win but it certainly contributed. But in reality – that is exactly what we were there to do – that was the time to be conservative and learn the lesson. The minute or so of lost time during the 2019 Channel Race could potentially yield many more minutes of time gained in next week’s Fastnet Race as we now has a very clear understanding of where and when the Code Zero becomes effective in our inventory. These lessons need to be learned some time – best to do it before the big one rather than during it! As always – time on the water is key!

Secondly and finally – a note on sail area. It is not the be-all and end-all, as we’ve just proven. Bigger is not always better. Design and effective application are far more important. So next time you think “throw up the biggest one we have!” stop and consider the situation – you may just find the net gain elsewhere.

Barry Hayes of UK Sailmakers Ireland goes through the options for racing boats to go Symmetrical or Asymmetrical with their spinnakers. Barry sailed aboard George Sisk's XP44 WOW from Royal Irish Yacht Club at this year's Sovereigns Cup, where WOW won all races in the Coastal Division. UK Sailmaker's boats also won Class One, Whitesail One and the 1720 Sportsboat divisions at the Cup.

In the past 10 or 15 years, spinnaker options have increased considerably. Prior to that, it was fairly straightforward. You bought a light air symmetric spinnaker, a heavy air version of the same and maybe a reaching spinnaker.

In recent years, however, Asymmetric spinnakers have become a lot more efficient and some yacht builders, particularly J boats, feature them almost exclusively on their models. Below we are going to do an analysis of which option is better for racing inshore/offshore.

First the pros and cons of each option:

Asymmetric Spinnakers


  • Easier trimmed and handled
  • IRC rating allows larger asymmetric spinnakers for the same rating, relative to symmetrics
  • Very efficient when reaching as shape allows better exhaust of the air.
  • Code 0 models (very flat Asymmetric) is a must for offshore boats


  • Needs a sprit or prodder to set them properly away from the bow.
  • They don’t run as deep and efficiently as Symmetric spinnakers.
  • In Heavy air, they sometimes can wrap around the forestay when gybing
  • Time is always lost gybing, compared to boats with poles

Symmetric Spinnakers


  • Once above 12 knots, they are very efficient running with pole pulled back.
  • Tactically, they offer a better crew, greater options downwind.
  • Very little time lost while gybing.


  • Expensive on IRC rating—On a J109 it costs about 7 points if you want the same sized spinnaker
  • Not as efficient when reaching due to shape
  • much more difficult to hoist and trim properly

At UK Sailmakers Ireland, we had a J109 client this year that opted to go for Symmetric spinnakers on a boat that is designed for A sails. Before we went down this route, we did extensive testing and trial certs to see what the benefits would be. The bottom line is that there is no perfect answer. Were you able to have two IRC certs (one Symmetric, one Asymmetric), and be able to select which one, each race, then you would have both set-ups.
However IRC does not allow this and most regattas insist you don’t change your cert in the last 10 days before a regatta, as long-range weather forecast details may play a part in your decision.

A number of other sprit boats have moved to Symmetric this year, including Anthony O'Leary’s converted 1720, Antix Beag from Royal Cork and Stephen Quinn’s J97 Lambay Rules from Howth.

Bottom Line —A sails are generally more efficient on normal cruisers in less than 12 knots than symmetric spinnakers. Why?

Up to 12 knots, most symmetric boats struggle to get their spinnaker poles back that far, as the spinnaker will collapse. So an A2 Asymmetric boat will likely be able to run as deep as an S2 Symmetric boat, but the A2 Asymmetric usually will have a larger spinnaker area and a lower rating. IRC, it appears, penalises a boat with a pole by about seven points (on a J109), for the ability to be able to pull the pole back and go deep.

In light airs, if you can’t get the pole back, then you are at a disadvantage. Add to that, an Asymmetric sail is more efficient going at higher angles, than boats with symmetric spinnaker.

Bottom Line—Symmetric spinnakers are more efficient running in more than 14 knots. Why?

Once a symmetric boat can get its pole fully back, it can normally nearly run square, or maybe 10 degrees off square. A similar designed boat with an Asymmetric spinnaker will likely go the same speed, but be 10 degrees or more higher. When the two boats get to the bottom mark, the Symmetric boat has likely pulled out 30 to 60 seconds. Add to this, the symmetric boat can throw in gybes easily to stay in wind or get away from other boats' wind shadows, and the gain becomes even larger. If the wind gets up to 20 knots or more running, the symmetric boats have an even bigger advantage.

Bottom Line—Asymmetric boats are generally more efficient offshore and on Coastal racing.

This is because the two scenarios above relate to running square downwind, as you would have in Windward Leeward racing. On offshore and coastal races, often there is a lot of reaching and broad reaching. The A sail boats then have their rating advantage, and the efficiency of the A sail when reaching.

Sovereigns Cup Coastal1George Sisk's XP 44 Wow on the way to winning Sovereigns Cup—Coastal with his Uni Titanium sails

What are the crewing considerations?

Trimming a symmetric spinnaker is considerably more difficult to do well, than trimming an Asymmetric spinnaker. A symmetric spinnaker needs the sheet adjusted constantly, the guy adjusting the angle of the pole is constantly being adjusted, as is the pole height and the spinnaker tweaker.

On an Asymmetric sail, it is generally just the A sail sheet that is adjusted. You may move the tackline in and out a bit, but not that much. As a result, to get the best out of a symmetrical spinnaker, more good crew are needed to trim it well.

What about boats having both sail setups?

Any boat opting for a symmetric setup should also be planning to take some Asymmetric spinnakers as well. To do this efficiently, it needs a small sprit or prodder, to use with the A-sail for reaching conditions. The IRC rule allows a prodder (or sprit) on a symmetrically configured boat, as long as the prodder does not extend out further than the pole does.

However, the A sail size (SPA) on these A sails cannot be any bigger than the largest symmetric spinnaker. So in the case of our J109 this year which went Symmetric, we opted for a 102 sq. metre Symmetric spinnaker, which is six sq metres smaller than the Class A sail size. This saved us two points off the rating,  so the seven-point hit for the pole was lessened to five points overall. The new A sails added, to cover her reaching requirements were a code 0 for light air reaching and an AO, for light air running. The AO can be used off the prodder, or can also be transferred to a lowered pole, with the pole being pulled back to allow further depth.

Cost Considerations

For an existing Symmetrical boat, changing to No pole and just using A sails would require,

  • A sprit
  • New Spinnaker specific A sail sheets
  • New Asymmetrical spinnakers
  • A tack line to attach the A sail to the Sprit

For an existing A sail boat, to go to Symmetrical configuration requires,

  • A pole
  • A track on the mast
  • additional Blocks etc. to cover sheets and guys and pole downhaul
  • Symmetrical spinnakers and perhaps some A sails as well.

For someone ordering a new boat—Best to try and incorporate both options from day one, even if only opting for one setup.

So –Which option to go for?

As I said in my opening paragraph, there is no perfect choice, but here is a quick plan.

  • For Light planing boats - Go A sail, as you will always be going higher angles
  • For short-handed - A sail is a lot easier for Handling
  • For Offshore/Coastal - A sail will likely be best, as more reaching than running
  • For Inshore, in lighter air areas, go A-sail
  • For Inshore in stronger wind areas - Go Symmetric.
  • For Inshore in mixed conditions -Either works, but Symmetric with a good crew might just have the edge if you also have some good A sail options as well.

The XP44 'WOW' stormed home to win the Coastal Class of Sovereigns Cup 2019 this month. The prize giving ensued after which began the bar talk debrief of the week between sailors from all boats writes Graham Curran of UK Sailmakers Ireland.

Some of this chat focused on WOW’s ‘secret weapon’ – her Flying Jib (FJ).

Flying Jibs, although new to Irish waters, have become common sights on offshore and coastal racers worldwide over the last couple of years. An FJ provides speed and stability while filling a tricky gap in the sail inventory between code zero and heavy reaching spinnaker. So what is involved? And what are the tangible benefits?

Bow Down; Power On

A common issue with a modern non-overlapping sail plan is an 'unbalance' when broad reaching – sometimes resulting in a broach to windward. This usually occurs when the breeze is up. Imagine broad reaching in 18 knots – you are too tight and pressed to hold your code zero, but not deep enough to set your A5 heavy reacher – so what do you do? Two sail the leg with your jib and main (hopefully with the jib on an outboard lead). At this point the boat is out of balance – the headsail will never produce as much power in front of the rig as the mainsail does behind it – unbalanced.

flying Jib UK Sails

Enter the Flying Jib

Flown off a bowsprit, to clear the forestay, the flying jib adds additional sail area to the front of the boat, encouraging the bow down. This extra force counteracts the power of the mainsail – thus balancing the boat. More than just sail area, the flying jib also creates a third ‘slot’ in the sail plan. More slots equals more power. More power, when correctly balanced, equals more speed.

This advantage became very apparently off Kinsale last Friday when WOW, trailing her bigger sister FREYA, was able to close the distance and catch the opposition with her flying jib deployed. The flying jib gave WOW an extra 1.5 knots of boat speed.

Ease of Use, Plug and Play

WOW’s flying jib and code zero are both set on anti-torsion cables which plug into her Ubi Maior ratchet furler. Both sails can be ready to hoist in seconds, quickly deployed, and safely recovered with the ratchet action of the furler preventing accidental deployment.

The sail is designed to sheet to the same point as the code zero so no additional sheets or hardware are needed. It is very much a complementary plug and play sail system.

WOW was the only boat in her fleet with a flying jib – she is equipped with a versatile modern performance sail plan for optimum sailing on all points of sail – bring your sail plan into the future with a UK Sailmakers Flying Jib.
