We developed a new design for the Shannon One design class at our Cork sail loft. Once we were all happy with the design which we sent to top guys in the class so they could review it in real time on a 3D viewer file.

We were then able to develop a sail to make the first prototype, which we built for the class with great success last season. The class trialled the sail over the season last year with some excellent results on the water. We then sat down at the end of the season and developed the sail even further. Using the 3D viewer file, we developed the sail shape another four times.

From there, we went on to develop the sail details another three times, from eyelets to reefs to battens, getting the very last detail right for future orders, which we got 14 of for this coming season.

These 14 sails were all measured last weekend by John Leech and Harry Croxon, who were delighted to see that the sails were all measured correctly the first time and that every detail was perfect.

John Leech said “I was very impressed with the one design precision and accuracy of all the sails and looking forward to seeing them in competing on the water".

We have had a very busy winter period getting your sails serviced, repaired and ready for 2024. Over 800kg of sails and covers sent to laundry are now back.

We were delighted to get so many sails and covers this season, way more than we have had before; we are getting everything ready for St. Patrick's Weekend so you can get out early.

As well as laundry, we have been really busy getting racing sails ready, checking their IRC, and sorting any nicks and scratches on them. Most of the racing sails are ready for the season ahead, with the last of them ready for action in early spring.

We have moved production

We have moved to a new production loft in Carrigaline, and opened up a shop in Crosshaven to better serve the needs of our customers; the new production loft is built to make and service sails.

New Plotter- Blackman & White

We have also bought a new Plotter (cutting machine to cut sails). To give us greater capability to produce sails with a modern machine. Our new machine is affectionally called Marvin2

Get your orders in. We still have the capacity to deliver new sails on time

We still have room for you if you want to get out early and make the most of 2024. As March is here and you're not sure the status of your sails. Or looking at your IRC cert and think it needs to be lower.

Our sail loft has been a sail service centre for over fifty years. Thousands of sails have been on our floor and it’s not often we see something we haven’t encountered before. We can spot issues before they emerge as serious problems. This will not only save you money – but also time.

No one wants their sails on our floor when they should be on your boat out sailing!

CLUB RACER

As we are the only IHC loft in Ireland, we can get your sails IRC measured and certified for the coming season. We still have room for more if you haven’t sent them in and your thinking of having a look. Now is the time.

When we receive your sails in our loft we give them a full check over. We check all luff tapes for tears, check common wear spots such as where they interact with spreaders and stanchions, check for missing telltils, and identify if there are any unknown causes for the problem which is presenting itself on the floor.

UK sailmakers Ireland are working hard to get you out early. It’s coming up soon and we want you to get the most of your 2024 season. So get out early!

While we have your sails we can re-measure them for IRC. This can lead to a nice reduction in your IRC handicap upon your revalidation for the 2020 season.

COASTAL CRUISER

If cruising or day sailing is your thing and you put your sails away last October. There is still time to get them checked and ready for the new season. I have seen many sails still on the boom in different boat yards and yacht clubs.

One of the worst thing you can do for your sails is leave them on your boat for a prolonged period of time – even during the sailing season. If you are not going to be using your boat for a month or more then take down the sails and store them.

Exposure to the sun degrades your sails and covers – this is simply a fact of life. The UV light breaks down the fabric and especially the stitching.

During the check-up, we inspect your entire UV cover and its stitching. A quick run through a sewing machine now is much more cost-effective than replacing an entire torn UV strip after an Irish winter storm. The same goes for your covers. Deliver them all to us together for a full assessment.

The UK Sailmakers Ireland sail loft in Crosshaven, Co Cork, has been a sail service centre for over forty years.

Thousands of sails have been on our floor, and we rarely see something we haven’t encountered before. We can spot issues before they emerge as serious problems. This will not only save you money – but also time. No one wants their sails on our floor when they should be on your boat out sailing!

Depending on the type of sailing you are doing, an ‘annual service’ can consist of many different things. Some may even ask, “Do I really need to?” The short answer is –yes, you do – let me explain why.

Club Racer

If you’re a club racer, then you’re the most likely to ask the “Do I really need to?” question. In fact, your sails will likely benefit more than anyone else from a good annual service.

When we receive your sails in our loft, we give them a full checkover. We check all luff tapes for tears, check common wear spots such as where it interacts with spreaders and stanchions, check for missing tell tails, and identify if there are any unknown causes for the problem which is presenting itself on the floor.

For example, we see many luff tape repairs throughout the season and during winter service. Luff tapes don’t just tear. If they tear then there is a reason why. Sometimes it can be a simple mistake of sheeting on too early or skipping the feeder – but often, there is a problem which can be solved on the boat. We discuss potential issues with our customers and present solutions to avoid damage occurring in the future.

While we have your sails, we can re-measure them for IRC. This can lead to a nice reduction in your IRC handicap upon your revalidation for the 2024 season.

Our expert staff pick up details which the untrained eye would overlook. Leverage this experience to protect your investment and maximize your time on the water come next spring.

Coastal Cruiser

If cruising or day sailing is your thing, then you likely have a UV strip on your headsail and plenty of covers, spray hoods, dodgers etc.

One of the worst things you can do for your sails is leave them on your boat for a prolonged period of time – even during the sailing season. If you are not going to be using your boat for a month or more, then take down the sails and store them aboard. If you only wear your good flamingo shirt to weddings, and you don’t have one for two months, you aren’t going to leave it hanging on the line!

Exposure to the sun degrades your sails and covers – this is simply a fact of life. The UV light breaks down the fabric and especially the stitching. During an annual check-up, we inspect your entire UV cover and its stitching. A quick run through a sewing machine now is much more cost-effective than having to replace an entire torn UV strip after an Irish winter storm. The same goes for your covers.

Deliver them all to us together for a full assessment.

Storage

When you are packing your boat up for the season, you should also be thinking about where you are going to store your sails. Definitely take them down, we’ve all seen furled headsails ragged by a winter storm, and take them off the boat and have them stored properly in a cool, dry, rodent-free place – our sail loft for example!

Even if you have your own space to store your sails; get them to the loft first. We see it every spring – ‘best intentions’ of getting your sails to us during the winter were packed away with them. Out of sight, out of mind. You then have to join the long line to get your small issue fixed when you could be out enjoying your sailing.

We have a purpose built storage area in our loft where we can keep your sails comfortable until you need them. We can also store your racing sails rolled – extending their life and keeping them nice and crisp.

Laundry & Re-Proofing

When we have your sails and covers for service, we also consider whether they are due a wash. Every year, we are asked to replace boom covers and spray hoods when all that is needed is a good wash, reproofing, and a few stitches here and there.

Sails and covers are washed to remove green mildew and general grime from the fabric. Covers are then re-waterproofed to give them an entirely new lease of life.

Now is the time!

Our schedule in filling up fast after a busy season on the water. Now is the time to get in contact and arrange your winter service. Let us ensure your sails are in top health and ready for your 2020 sailing season.

Wear and tear can destroy almost any part of your sail. You pad and tape the lifelines and put chafe guards on. You put covers on spreader tips. All these things protect your sails, but your sails can suffer from abrasion and folding as well. Every time you tack, your sails will flutter, bending threads and slowly breaking down the sailcloth over time. And, if you have an overlapping Genoa, the constant brushing over the mast and shrouds will eventually cause wear on the laminate

What can you do to protect your sails and extend their performance life? One solution is to purchase sails with a protective coating of a light taffeta on one or both sides of the sail. The taffeta we’re talking about is a durable fabric made from twisted polyester yarns. These panels of taffeta can be laminated to mylar sailcloth when the sailcloth is being manufactured.

Simply put, a protective layer of taffeta will strengthen, protect, and extend the life of a sail. Ranging in thickness from 1.0mil to 2.0mil, you can order a sail made with taffeta already bonded to one side (preferred) or you can have UK Sailmakers apply a layer of taffeta to an existing sail. In either case, the value represented by the extended performance life of the sail vs. any cost implications makes taffeta a wise decision.

An additional benefit of adding taffeta is that it helps create a firm, stable, and durable structure when laminated, allowing the sailmaker to reduce the weight of the core mylar or woven film helping keep the sail as light as possible.

There are two schools of thinking regarding how much taffeta is needed. For sails where you want to dramatically extend peak performance life, full coverage of one side is recommended – ideally using a base sailcloth with integrated taffeta mentioned above. To protect the sail even more, on the film side, you can have a taffeta “wave” applied, a wide strip of taffeta that follows the shape of the sail down the leech and forward across the foot. This taffeta wave adds a layer of protection against abrasion where it is needed most, without adding extra weight and bulk to the entire sail.

That said, many cruising boats going offshore or those sailing in races like the Fastnet opt for full taffeta on both sides of the sail. This makes the sail extremely strong and durable, although it does add to the sail’s overall weight.

The majority of the taffeta sailmakers use comes from Germany, India, or Taiwan and comes in white, grey, or black. Regardless of colour, the taffeta material itself comes in 3 primary formats:

  • 50x 50 – Light taffeta, Taffeta L, which is about 1 sm-oz when laminated to a film.
  • 50x 150 – Medium taffeta, Taffeta M, which is about 1.3 sm-oz when laminated to a film.
  • 150x 150 – Heavy taffeta, Taffeta H, which is about 1.8 sm-oz when laminated to a film.

Approximately 90 % of all boats in Ireland with taffeta only need Taff L or Taff M; anything more would be too heavy.

An example of taffeta laminated onto mylar is the Radial laminate DCX from Dimension Polyant. This is a very durable lightweight radial laminate used on most cruising and performance cruising boats. And taffeta protective coatings are not just for mains and jibs, today’s Code 0s are made with very light taffeta coatings, too.

One final note, because taffeta will absorb some water, the sail can add weight in certain situations. As such, taffeta-coated sails are not well suited for one-designs like 1720s or J/70s that are normally better off with quick dry, lightweight mylar sails. However, if you have a J/80 with a furling headsail, a taffeta headsail would be really good as it would add to the durability of the furling sail.

A-sail design principles are often misunderstood. Top sailmakers explain...

To explain the thinking that goes into designing asymmetrical spinnakers, UK Sails Ireland interviewed three sail designers from UK Sailmakers: lead designer Pat Considine, UK Sailmakers Chicago; Geoff Bishop, UK Sailmakers Fremantle, and Stuart Dahlgren, UK Sailmakers Northwest - Sidney, BC. Their thoughts on spinnaker design fell into two buckets.

1. The boat itself

Type of boat - high-performance, displacement, one-design.
Exact measurements - pin-to-pin halyard length, sheeting position, etc.

2. The type of sailing to be done

IRC, ORC, offshore, coastal, one design, professional vs. Corinthian

Key data points

When designing an asymmetrical spinnaker, a designer will focus on three primary data points:

  1. The point-to-point distance between where the spinnaker will be tacked (on a sprit or a lowered pole) and the max height for the halyard.
  2. The mid-girth (SMG) luff to leech measurement, expressed as a percentage of the foot length.
  3. The trim position for the clew in terms of height off the deck and where the sheet will lead.

Pat Considine explains: ‘A symmetrical spinnaker is probably the easiest sail to design. It has no twist and both sides are the same. An asymmetrical spinnaker, on the other hand, is challenging to design because the luff is free flying, there’s twist in the leech and there are many other things to consider.’

Our sailmaker panel agreed that once the boat characteristics and racing plans are known, additional pre-design considerations include:

  • The performance characteristics of the boat such as polars, reaching/running angles and so on
  • The other spinnakers in the inventory: can this new sail have a narrow range or should it be all-purpose?
  • Rating system to be sailed, optimisation for IRC, ORC, etc
  • Budget: Yes, there is less expensive nylon and more expensive nylon. With spinnakers you get
    what you pay for
  • The skill of the owner: experienced sailors (helm and trimmers) will not need as forgiving a
    spinnaker as less experienced sailors.

Geoff Bishop adds: ‘Once you get a good sail design and you know the boat’s measurements, you pretty much stick with it. That said, the critical thing for me is getting the luff length and the mid-girth ratio right.

‘Start with the straight-line measurement from the tack to the max hoist position (straight line), the tack point to the sheeting position, plus the sheeting position to the max hoist position. It’s critical to get those measurements right because every percent of difference in mid-girth in relation to the foot and luff length changes performance and ratings.’

A running sail could have a 105% mid-girth (SMG) of the foot length (SF) and a luff length longer than the straight-line measurement. Conversely, a reaching sail will have a smaller SMG in relation to the foot length as well as a shorter luff.

It’s crucial to understand how these parameters affect a sail’s performance when asking a sailmaker to design a new A-sail

Luff length

The luff length helps to determine the projection of the sail. For windward/leeward racing, mostly in displacement boats, the goal is to soak for VMG. For that you want a luff that is longer than the pin-to-pin measurement; this creates positive luff curve allowing the sail to project to windward further so you can sail deeper on those shorter round-the-buoys races. If a spinnaker luff keeps collapsing when properly trimmed, the entry is probably too flat. One of your tools is the tackline: if it has been eased to allow more projection, pull it back down to help round the entry, making it easier to trim.

To design a good A-sail, the entry must be deep enough to support the luff round and allow the luff to curl without collapsing. Consider a heavy J1 jib. To sail that J1 upwind in a groove, you need curvature in the luff so the telltales work. Reachers (A1, A3, A5) will be designed flatter and straighter in the aft section to avoid the sail getting overpowered too quickly. Runners (A2, A4) tend to have deeper, rounder aft sections.

For running asyms, the luff length can range from 105-112% of the pin-to-pin measurement. 112% would be for a boat like a J/120 where projection is important. The longer luff helps to increase projection when sailing at the deeper angles.

Tweakers are another tool that can be used to improve your sail’s performance. As the sheet is eased the active tweaker should be tensioned, effectively moving the sheet lead forward, this controls twist and allows the designed depth to be maintained, so that the head doesn’t flip open as the sail is eased.

All these contributing factors that make displacement boats’ VMG quick downwind are your enemies when sailing a performance boat offshore in waves. Unlike displacement boats, performance boats generate tremendous amounts of apparent wind. With the apparent wind angle rarely aft of 110 degrees, the helmsperson will drive down to surf waves then turn up to regain speed and height.

Displacement boats also may surf down a wave moving the apparent wind forward but when they put the bow up to dig out of the trough, they won’t respond as quickly. Also, the apparent wind shifts relatively more than on a performance boat.

Offshore and coastal running sails generally have the same depth, but what differs would be the luff length defining the luff round, and the overall projection of the luff. This is achieved by designing the
sail’s optimal flying shape and then engineering the panel layout to handle the loads and maintain stability.

Sailing in waves you “drive” the boat more aggressively moving the apparent wind more dynamically. If conditions allow the boat to be stable, it’s great to have a super long luff; but when the boat starts to move around under the sail, oscillation increases as do the chances of collapse or wrapping the sail around the forestay. There is also the physical limitation on how long the crew can keep up aggressively trimming the sheet in a distance race.

Because of the relatively smaller shifts in apparent wind angle in performance boats, their offshore spinnakers are cut flatter with a tighter luff. This design will be more resistant to collapsing from a serpentine steering pattern through waves. By adjusting the tackline you have more range with this sail.

Mid-girth measurement (SMG)

A big difference between one-design or coastal and offshore spinnakers is the mid-girth measurement (SMG). Offshore, where you typically sail at higher wind angles, your asym’s SMG is likely to be narrower depending on whether it is an A1, A3 or A5. Coastal or one-design spinnakers, used more for VMG running (A2 and A4) will have a wider SMG, as you’re looking to soak deeper. This wider SMG design will allow the sail to rotate out in front and to windward further in the VMG soak mode.

Above: an asymmetric spinnaker rotates as the sheet is eased. A wider SMG (mid-girth measurement) allows it to rotate further in front and to windward, which is ideal for inshore racing in a displacement boat. Sails for offshore use and for fast planing boats tend to have a narrower SMG which is more efficient at tighter wind angles.)Above: an asymmetric spinnaker rotates as the sheet is eased. A wider SMG (mid-girth measurement) allows it to rotate further in front and to windward, which is ideal for inshore racing in a displacement boat. Sails for offshore use and for fast planing boats tend to have a narrower SMG which is more efficient at tighter wind angles.)

Sheeting position/leech length

The leech in an offshore asymmetric isn’t much different than a coastal or one-design sail, yet it’s still critical to get the clew height and sheeting angle right. The amount of fullness in the back end comes down to the type of spinnaker it is. Reachers are flatter in their aft sections so that you don’t get overpowered as quickly. Runners’ leech sections tend to be rounder, generating more power.

Pat Considine continues: ‘With our computer design software, it’s very easy for us to change the depth of the sail, but it’s important that you understand the corner-to-corner loads. Someone may be looking to save time and money by designing an asym with fewer panels but that’s no good because of the bias loads going across the panels. Designing a sail to have more panels that are narrower will result in a structurally stronger sail. We orient panels so the warp and fill yarns reflect the load paths of the sail. We also specify heavier fabric with narrower panels in luff, where most of the load is.’

Tweaking the leech shape

As the true wind angles being sailed change, you will want to control the leech shape and sheeting angle of the sail. Attaching a tweaker to the sheet allows you to raise or lower the sheeting angle and optimize the twist and exit angle of the sail.

Geoff Bishop notes: ‘With our running sails, if you’re in eight knots with a 150-degree target angle, we’d put on a little tweaker. But if we had to head up to 140 degrees to gain speed, we’d release the tweaker. We constantly play the tweaker up and down to optimise leech shape and control twist.’
Overtightening the tweaker will close the leech and prevent it from exhausting properly. To sail deeper angles, ease the sheet so the sail rotates forward and tension the tweaker to control twist.

Summary

Taking the time to understand the boat and the manner of sailing it will do is critical to designing and building an asymmetrical spinnaker that will help you win races. After that, it’s up to you to properly adjust and set the spinnaker so it will match the design’s optimal flying shape.

If you are looking for a new asymmetrical spinnaker for your boat, don’t just take what you’re given. Ask questions about the key measurement points of the sail, understand the performance differences of various options and then practice to sail it effectively. If you do this, you’ll be able to sail with confidence.

It has been a busy summer here in UK Sailmakers Ireland with Dun Laoghaire regatta and other regattas. We are pleased to report that we were up to the challenge of getting sails made and ready on time despite the obstacles posed by worldwide supply chain issues.

Luckily for our customers, we make many of our sails locally, right here in Crosshaven, so our customers were able to receive their new sails in time for their regattas. That’s not a claim every sailmaker can make.

From 1720 spinnakers to Howth 17s and Mermaid sails, we have also started making Shannon one design sails, which are proving their worth on the race course. This is the level of professional customer service sailors have come to expect from UK Sailmakers, and that’s a responsibility we take seriously.

Having the ability to design and produce sails in Ireland is a key feature of our loft. With the resident sailmaking know-how right here, sailors can discuss their new sails face-to-face with the sailmakers who will be building them. That is a rare and very special part of what makes UK Sailmakers Ireland stand out in the marketplace.

Although we make many of our own sails, some are made at the UK Sailmakers loft in Hong Kong. With supply chain issues not expected to ease up in the near future and with an early Chinese New Year expected to disrupt deliveries further, we are advising our customers to talk to us now about new sail requests so we can meet delivery expectations.

As autumn draws to a close, our Winter Discount programme kicks in from September 1st until December 1st, giving you time to inspect your sails one last time and see what’s needed for the new season starting in March.

Get in early, get out early, and sail with confidence.

Adam Perry from the Royal Yachting Association (RYA) was at UK Sailmakers Ireland loft in Crosshaven, County Cork, this week  (7th of June 2023) for the refreshing of its In-House Certification (IHC).

The Cork loft is the only IHC loft in Ireland and has been since Des McWilliam's days, but it must renew this status every three years as per World Sailing requirements.

To that end, Adam from the RYA was in the loft to check over the loft’s records and measurement methods to confirm the required consistency with worldwide practice and renew their licence.

We’re getting very close now. It’s just around the corner; this time next weekend, you will hopefully be in Dick Mac’s in Dingle having a refreshing pint!

So how is it looking for the Dun Laoghaire to Dingle Race (D2D) next week, and what should be occupying the minds of skippers over the weekend?

At this stage, boats should be cleaned and washed above and below the waterline and could probably be set into ‘race mode’ ahead of the start on Wednesday.

Provisioning is probably well underway, and a big lesson is to make sure there is enough water! A minimum of 2.5 litres per person per day! Minimum.

We will be running a weather briefing on Tuesday evening and will be available to answer questions on Wednesday morning, but the long-term forecast is for spinnakers!

The D2D fleet should get the benefit of the tide around Wicklow Head and use this to carry themselves mostly to Tuskar RockThe D2D fleet should get the benefit of the tide around Wicklow Head and use this to carry themselves mostly to Tuskar Rock

There is a very dominant high pressure to the North of Ireland that looks set to stay there until next week and into next weekend…. This is giving us downwind conditions all the way to Dingle at present.

With a start time set that would be used for a perfect passage if one was to head south tide-wise, the fleet should get the benefit of the tide around Wicklow Head and use this to carry themselves mostly to Tuskar. The faster boats may stay in this tide all the way to Tuskar in the dying few hours of the southerly flow. Slower boats may unfortunately not make Tuskar and may end up punching into the tide as they approach the lighthouse…. It will be interesting when we run the routings to see if it might even pay to go outside the Tuskar TSS!

Wind-wise, initially, with a lot of change likely to happen in the next few days, the fleet is likely to start in a strong sea breeze out of Dun Laoghaire, and once around Muglins, this could die off. Wind within sight of the land looks good down the Wexford coast, with there likely to be running VMG conditions gybing in and off the coast. Through Wednesday night, look out for a transition with the wind going forward to being on the bean towards Tuskar.

Into Thursday, this easterly wind is likely to stay with slightly more breeze offshore; once again, it will be VMG running conditions in the direction of the Fastnet. There is likely to be some compression off the Fastnet with a bit more breeze in that area but expect the race to be quick along the south coast.

There is likely to be some compression off the Fastnet with a bit more breeze in that area but expect the D2D race to be quick along the south coastThere is likely to be some compression off the Fastnet with a bit more breeze in that area but expect the D2D race to be quick along the south coast

The wind will likely follow the fleet around Baltimore and Goleen, keeping the running VMG theme going!

Unfortunately, early forecasts show little wind off Dingle; still time to win or lose the race here! Keep the concentration up!

As I said, this is a very, very early look at what MIGHT happen, not to be relied on yet!

Make sure to come to the briefing on Tuesday night, where we will discuss this in more detail.

With a race starting on the 7th of June, there are a little over three weeks to the start of this year’s edition of the challenging Volvo Dun Laoghaire to Dingle Race. So what should boats and crews be thinking about?

Kenny Rumball, who has competed in the race many times, taking class wins and line honours, has some top tips in collaboration with UK Sailmakers Ireland and Offshore Racing Academy.

Boat prep…

Although the weather is unlikely to be too harsh for this race, it can be… one year we actually had to pull out on a J109 into Dunmore East after an upwind hammering the night before all the way from the start. As such, now is the time to check your rig, standing and running rigging, winches, clutches etc. A lot of time, money and effort goes into a race, so let’s control the controllable, one of which is the boat. A few solid days on the boat with the crew in the sun, checking crucial items could mean the difference between finishing or not.

Sails…

‘The powerhouse of our boat, they are what will get us there under sail or not. Those who have competed in the first few ISORA races have been pretty light…. Have we had all the sails in the air and checked them ahead of the race? The last thing we want is to hoist the J3/J4 when we really need it to find its missing battens or, worse still, has a massive hole in it! For those seeking that extra edge in performance and trying to optimise their rating, it’s no secret that sails shrink! When was the last time your sails were re-measured? You never know how much they have shrunk, and this can lead to a few key crucial points on the cert!’

Now is the time to log important waypoints and dangers into your chart plotter or computer Now is the time to log important waypoints and dangers into your chart plotter or computer

Navigation & Routing

‘Something that is talked about in the bar more than anywhere else, routings, ETAs, going inside our outside banks etc. The most important part is to look at the safety side of things navigation-wise. Now is the time to log important waypoints and dangers into your chart plotter or computer rather than the night before! In the most basic part, we can predict the tides with confidence. The start is scheduled for 1400, and with high water that day at 1504; this is the perfect time if you wanted to catch the south-going tide past Wicklow head; worth looking at a tidal atlas to see where the tide runs fastest inshore or offshore….

To help competitors on this, I will be running a weather briefing and some routing simulations the night before the race in the National Yacht Club, where I’ll be able to answer some last-minute questions.

Logistics

Logistically offshore races such as the D2D can be a challenge, finishing in a different port to the start and away from home. Don’t forget the basics to allow you to enjoy the event fully! Dingle is busy; book accommodation early!

For those boats looking to save weight on board, we in the Offshore Racing Academy are providing our bag drop service, checkout this link for more information!

We’ll have more information soon, however, if you need anything, don’t hesitate to contact the loft…

General Information on using Waterways Ireland inland navigations

Safety on the Water

All users of the navigations are strongly recommended to make themselves aware of safety on the water for whatever activity they are involved in and to read the advice offered by the various governing bodies and by:

The Dept. of Transport, Ireland: www.gov.ie/transport and The Maritime and Coastguard Agency, UK, The RNLI – Water Safety Ireland for information in terms of drowning prevention and water safety.

Registration of Vessels

All vessels using the Shannon Navigation, which includes the Shannon-Erne Waterways and the Erne System must be registered with Waterways Ireland. Only open undecked boats with an engine of 15 horsepower or less on the Shannon Navigation, and vessels of 10 horsepower or less on the Erne System, are exempt. Registration is free of charge.

Craft registration should be completed online at: https://www.waterwaysireland.org/online-services/craft-registration

Permits for use of the Grand and Royal Canals and the Barrow Navigation

All vessels using the Grand and Royal Canals and the Barrow Navigation must display appropriate valid Permit(s) i.e A Combined Mooring and Passage Permit (€126) and if not intending to move every five days, an Extended Mooring Permit (€152).

Permit applications should be completed online at: https://www.waterwaysireland.org/online-services/canal-permits

Passage on the Royal and Grand Canals – Dublin Area

For boat passage through the locks east of Lock 12 into / out of Dublin on either the Royal or Grand Canals, Masters are requested to contact the Waterways Ireland Eastern Regional Office (M-F 9.30am-4.30pm) on tel: +353(0)1 868 0148 or email [email protected] prior to making passage in order to plan the necessary lock-keeping assistance arrangements.

On the Grand Canal a minimum of two days notice prior to the planned passage should be given, masters should note that with the exception of pre-arranged events, a maximum of 2 boats per day will be taken through the locks, travelling either east or west.

Movements in or out of the city will be organised by prior arrangement to take place as a single movement in one day. Boaters will be facilitated to travel the system if their passage is considered to be safe by Waterways Ireland and they have the valid permit(s) for mooring and passage.

Newcomen Lifting Bridge

On the Royal Canal two weeks’ notice of bridge passage (Newcomen Lifting Bridge) is required for the pre-set lift date, and lock assistance will then also be arranged. A minimum of 2 boats is required for a bridge lift to go ahead.

Waterways Ireland Eastern Regional Office (Tel: +353(0)1 868 0148 or [email protected] ) is the point of contact for the bridge lift.

A maximum number of boats passing will be implemented to keep to the times given above for the planned lifts (16 for the Sat / Sun lifts & 8 for the weekday lifts). Priority will be given on a first come first served basis.

On day of lift, boaters and passengers must follow guidance from Waterways Ireland staff about sequence of passage under bridge & through Lock 1, and must remain within signed and designated areas.

Events Held on the Waterways

All organised events taking place on the waterways must have the prior approval of Waterways Ireland. This is a twelve week process and application forms must be accompanied with the appropriate insurance, signed indemnity and risk assessment. The application should be completed on the Waterways Ireland events page at :

https://www.waterwaysireland.org/online-services/event-approval

Time Limits on Mooring in Public Harbours

On the Shannon Navigation and the Shannon-Erne Waterway craft may berth in public harbours for five consecutive days or a total of seven days in any one month.

On the Erne System, revised Bye Laws state that: No master or owner shall permit a vessel, boat or any floating or sunken object to remain moored at or in the vicinity of any public mooring, including mooring at any other public mooring within 3 kilometres of that location, for more than 3 consecutive days and shall not moor at that same mooring or any other public mooring within 3 kilometres of that location within the following 3 consecutive days without prior permission by an authorised official.

Winter Mooring on the Shannon Navigation and Shannon Erne Waterway

Winter mooring may be availed of by owners during the period 1 Nov to 31 Mar by prior arrangement and payment of a charge of €63.50 per craft. Craft not availing of Winter Mooring must continue to comply with the “5 Day Rule”. Winter Mooring applications should be completed online at : https://www.waterwaysireland.org/online-services/winter-moorings-booking

Owners should be aware that electricity supply and water supply to public moorings is disconnected for the winter months. This is to protect against frost damage, to reduce running costs and to minimise maintenance requirements during the winter months.

Vessel owners are advised that advance purchasing of electricity on the power bollards leading up to the disconnection date should be minimal. Electricity credit existing on the bollards will not be recoverable after the winter decommissioning date. Both services will be reinstated prior to the commencement of the next boating season.

Smart Cards

Waterways Ireland smart cards are used to operate locks on the Shannon Erne Waterway, to access the service blocks, to use the pump-outs along the navigations, to avail of electrical power at Waterways Ireland jetties.

Berthing in Public Harbours

Masters are reminded of the following:

  • Equip their vessel with mooring lines of appropriate length and strength and only secure their craft to mooring bollards and cleats provided for this purpose.
  • Ensure the available berth is suitable to the length of your vessel, do not overhang the mooring especially on finger moorings on floating pontoon moorings.
  • Ensure mooring lines, electric cables and fresh water hoses do not create a trip hazard on public jetties for others users.
  • Carry sufficient fenders to prevent damage to your own vessel, other vessels and WI property.
  • Allow sufficient space between your vessel and the vessel ahead /astern (c.1m) for fire safety purposes and /or to recover somebody from the water.
  • Do not berth more than two vessels side by side and ensure there is safe access/egress at all times between vessels and onto the harbour itself.
  • Do not berth in such a way to prevent use of harbour safety ladders, slipways or pump-outs.
  • Do not allow the bow of your vessel to overhang the walkway of a floating mooring thus creating a hazard for others with an overhanging anchor or bow fendering.
  • Animals are not allowed to be loose or stray at any time.
  • Harbour and jetty infrastructure such as railings, power pedestals, fresh water taps, electric light poles, safety bollards, ladders etc are not designed for the purpose of mooring craft , they will not bear the strain of a vessel and will be damaged.
  • At Carrybridge on the Erne System, Masters of vessels are not permitted to use stern on mooring. Masters of vessels must use the mooring fingers for mooring of vessels and for embarkation / disembarkation from vessels.

Passenger Vessel Berths

Masters of vessels should not berth on passenger vessel berths where it is indicated that an arrival is imminent. Passenger vessels plying the navigations generally only occupy the berths to embark and disembark passengers and rarely remain on the berths for extended periods or overnight.

Lock Lead-in Jetties

Lead-in jetties adjacent to the upstream and downstream gates at lock chambers are solely for the purpose of craft waiting to use the lock and should not be used for long term berthing.

Vessel Wake

Vessel wake, that is, the wave generated by the passage of the boat through the water, can sometimes be large, powerful and destructive depending on the hull shape and engine power of the vessel. This wake can be detrimental to other users of the navigation when it strikes their craft or inundates the shoreline or riverbank. Masters are requested to frequently look behind and check the effect of their wake / wash particularly when passing moored vessels, on entering harbours and approaching jetties and to be aware of people pursuing other activities such as fishing on the riverbank.

Speed Restriction

A vessel or boat shall not be navigated on the Shannon Navigation at a speed in excess of 5 kph when within 200 metres of a bridge, quay, jetty or wharf, when in a harbour or canal or when passing within 100 metres of a moored vessel or boat.

Vessels navigating the Shannon-Erne Waterway should observe the general 5 kph speed limit which applies along the waterway. This is necessary in order to prevent damage to the banks caused by excessive wash from vessels.

Vessels navigating the Erne System should observe the statutory 5kt / 6mph / 10kph speed limit areas.

A craft on the Royal and Grand canals shall not be navigated at a speed in excess of 6km per hour.

A craft on the Barrow Navigation shall not be navigated at a speed in excess of 11km per hour except as necessary for safe navigation in conditions of fast flow.

Bank Erosion

Narrow sections of all the navigations are particularly prone to bank erosion due to the large wash generated by some craft. Masters are requested to be vigilant and to slow down to a speed sufficient to maintain steerage when they observe the wash of their craft inundating the river banks.

Unusual Waterborne Activity

Unusual waterborne vessels may be encountered from time to time, such as, hovercraft or amphibious aircraft / seaplanes. Masters of such craft are reminded to apply the normal “Rule of the Road” when they meet conventional craft on the water and to allow extra room to manoeuvre in the interest of safety.

Sailing Activity

Mariners will encounter large numbers of sailing dinghies from late June to August in the vicinity of Lough Derg, Lough Ree and Lower Lough Erne. Sailing courses are marked by yellow buoys to suit weather conditions on the day. Vessels should proceed at slow speed and with due caution and observe the rules of navigation when passing these fleets, as many of the participants are junior sailors under training.

Rowing

Mariners should expect to meet canoes and vessels under oars on any part of the navigations, but more so in the vicinity of Athlone, Carrick-on-Shannon, Coleraine, Enniskillen and Limerick. Masters are reminded to proceed at slow speed and especially to reduce their wash to a minimum when passing these craft as they can be easily upset and swamped due to their very low freeboard and always be prepared to give way in any given traffic situation.

Canoeing

Canoeing is an adventure sport and participants are strongly recommended to seek the advice of the sport’s governing bodies i.e Canoeing Ireland and the Canoe Association of Northern Ireland, before venturing onto the navigations.

Persons in charge of canoes are reminded of the inherent danger to these craft associated with operating close to weirs, sluice gates, locks and other infrastructure particularly when rivers are in flood and large volumes of water are moving through the navigations due to general flood conditions or very heavy localised precipitation e.g. turbulent and broken water, stopper waves. Shooting weirs is prohibited without prior permission of Waterways Ireland.

Canoeists should check with lockkeepers prior entering a lock to ensure passage is done in a safe manner. Portage is required at all unmanned locks.

Canoe Trail Network – "Blueways"

Masters of powered craft are reminded that a canoe trail network is being developed across all navigations and to expect more organised canoeing along these trails necessitating slow speed and minimum wash when encountering canoeists, rowing boats etc

Rockingham and Drummans Island Canals – Lough Key

It is expected that work on Rockingham and Drummans Island Canals on Lough Key will be completed in 2021. Access to these canals will be for non-powered craft only, eg canoes, kayaks, rowing boats.

Fast Powerboats and Personal Watercraft (Jet Skis)

Masters of Fast Powerboats (speed greater than 17kts) and Personal Watercraft (i.e.Jet Skis) are reminded of the inherent dangers associated with high speed on the water and especially in the confines of small bays and narrow sections of the navigations. Keeping a proper look-out, making early alterations to course and /or reducing speed will avoid conflict with slower vessels using the navigation. Personal Watercraft are not permitted to be used on the canals.

Towing Waterskiers, Wakeboarders, Doughnuts etc

Masters of vessels engaged in any of these activities are reminded of the manoeuvring constraints imposed upon their vessel by the tow and of the added responsibilities that they have to the person(s) being towed. These activities should be conducted in areas which are clear of conflicting traffic. It is highly recommended that a person additional to the master be carried to act as a “look-out” to keep the tow under observation at all times.

Prohibition on Swimming

Swimming in the navigable channel, particularly at bridges, is dangerous and is prohibited due to the risk of being run over by a vessel underway in the navigation.

Age Restrictions on operating of powered craft

In the Republic of Ireland, Statutory Instrument 921 of 2005 provides the legal requirements regarding the minimum age for operating of powered craft. The Statutory Instrument contains the following requirements:

- The master or owner of a personal watercraft or a fast power craft shall take all reasonable steps to ensure that a person who has not attained the age of 16 years does not operate or control the craft

- The master or owner of a pleasure craft powered by an engine with a rating of more than 5 horse power or 3.7 kilowatts shall take all reasonable steps to ensure that a person who has not attained the age of 12 years does not operate or control the craft.

Lifejackets and Personal Flotation Devices (PFDs)

Lifejackets and PFD’s are the single most important items of personal protective equipment to be used on a vessel and should be worn especially when the vessel is being manoeuvred such as entering / departing a lock, anchoring, coming alongside or departing a jetty or quayside.

In the Republic of Ireland, Statutory Instrument 921 of 2005 provides the legal requirements regarding the wearing of Personal Flotation Devices. The Statutory Instrument contains the following requirements:

- The master or owner of a pleasure craft (other than a personal watercraft) shall ensure, that there are, at all times on board the craft, sufficient suitable personal flotation devices for each person on board.

- A person on a pleasure craft (other than a personal watercraft) of less than 7 metres length overall shall wear a suitable personal flotation device while on board an open craft or while on the deck of decked craft, other than when the craft is made fast to the shore or at anchor.

- The master or owner of a pleasure craft (other than a personal watercraft) shall take all reasonable steps to ensure that a person who has not attained the age of 16 years complies with paragraph above.

- The master or owner of a pleasure craft (other than a personal watercraft), shall take all reasonable steps to ensure that a person who has not attained the age of 16 years wears a suitable personal flotation device while on board an open craft or while on the deck of a decked craft other than when it is made fast to the shore or at anchor.

- The master or owner of a pleasure craft (other than a personal watercraft) shall take all reasonable steps to ensure that a person wears a suitable personal flotation device, at all times while – (a) being towed by the craft, (b) on board a vessel or object of any kind which is being towed by the craft.

Firing Range Danger Area – Lough Ree

The attention of mariners is drawn to the Irish Defence Forces Firing Range situated in the vicinity of buoys No’s 2 and 3, on Lough Ree on the Shannon Navigation. This range is used regularly for live firing exercises, throughout the year, all boats and vessels should stay clear of the area marked with yellow buoys showing a yellow "X" topmark and displaying the word "Danger".

Shannon Navigation, Portumna Swing Bridge Tolls

No attempt should be made by Masters’ of vessels to pay the bridge toll while making way through the bridge opening. Payment will only be taken by the Collector from Masters when they are secured alongside the jetties north and south of the bridge.

Navigating from Killaloe to Limerick on the Shannon Navigation

The navigation from Killaloe to Limerick involves passage through Ardnacrusha locks, the associated headrace and tailrace and the Abbey River into Limerick City. Careful passage planning is required to undertake this voyage. Considerations include: lock passage at Ardnacrusha, water flow in the navigation, airdraft under bridges on Abbey River in Limerick, state of tide in Limerick

Users are advised to contact the ESB Ardnacrusha hydroelectric power station (00353 (0)87 9970131) 48 hours in advance of commencing their journey to book passage through the locks at Ardnacrusha. It is NOT advised to undertake a voyage if more than one turbine is operating (20MW), due to the increased velocity of flow in the navigation channel, which can be dangerous. To ascertain automatically in real time how many turbines are running, users can phone +353 (0)87 6477229.

For safety reasons the ESB has advised that only powered craft with a capacity in excess of 5 knots are allowed to enter Ardnacrusha Headrace and Tailrace Canals.

Passage through Sarsfield Lock should be booked on +353-87-7972998, on the day prior to travel and it should be noted also that transit is not possible two hours either side of low water.

A Hydrographic survey in 2020 of the navigation channel revealed that the approach from Shannon Bridge to Sarsfield Lock and the Dock area has silted up. Masters of vessels and water users are advised to navigate to the Lock from Shannon bridge on a rising tide one or two hours before High Tide.

Lower Bann Navigation

The attention of all users is drawn to the “Users Code for the Lower Bann”, in particular to that section covering “Flow in the River” outlining the dangers for users both on the banks and in the navigation, associated with high flow rates when the river is in spate. Canoeists should consult and carry a copy of the “Lower Bann Canoe Trail” guide issued by the Canoe Association of Northern Ireland. Users should also contact the DfI Rivers Coleraine, who is responsible for regulating the flow rates on the river, for advisory information on the flow rates to be expected on any given day.

DfI Rivers Coleraine. Tel: 0044 28 7034 2357 Email: [email protected]

Lower Bann Navigation – Newferry – No wake zone

A No Wake Zone exists on the Lower Bann Navigation at Newferry. Masters of vessels are requested to proceed at a slow speed and create no wake while passing the jetties and slipways at Newferry.

Overhead Power Lines (OHPL) and Air draft

All Masters must be aware of the dangers associated with overhead power lines, in particular sailing vessels and workboats with cranes or large air drafts. Voyage planning is a necessity in order to identify the location of overhead lines crossing the navigation.

Overhead power line heights on the River Shannon are maintained at 12.6metres (40 feet) from Normal Summer level for that section of navigation, masters of vessels with a large air draft should proceed with caution and make additional allowances when water levels are high.

If a vessel or its equipment comes into contact with an OHPL the operator should NOT attempt to move the vessel or equipment. The conductor may still be alive or re-energise automatically. Maintain a safe distance and prevent third parties from approaching due to risk of arcing. Contact the emergency services for assistance.

Anglers are also reminded that a minimum ground distance of 30 metres should be maintained from overhead power lines when using a rod and line.

Submarine Cables and Pipes

Masters of vessels are reminded not to anchor their vessels in the vicinity of submarine cables or pipes in case they foul their anchor or damage the cables or pipes. Look to the river banks for signage indicating their presence.

Water Levels - Precautions

Low Water Levels:

When water levels fall below normal summer levels masters should be aware of:

Navigation

To reduce the risk of grounding masters should navigate on or near the centreline of the channel, avoid short cutting in dog-legged channels and navigating too close to navigation markers.

Proceeding at a slow speed will also reduce “squat” effect i.e. where the vessel tends to sit lower in the water as a consequence of higher speed.

Slipways

Reduced slipway length available under the water surface and the possibility of launching trailers dropping off the end of the concrete apron.

More slipway surface susceptible to weed growth requiring care while engaged in launching boats, from slipping and sliding on the slope. Note also that launching vehicles may not be able to get sufficient traction on the slipway once the craft is launched to get up the incline.

Bank Erosion

Very dry riverbanks are more susceptible to erosion from vessel wash.

Lock Share

Maximising on the number of vessels in a lock will ensure that the total volume of water moving downstream is decreased. Lock cycles should be used for vessels travelling each way.

High Water Levels:

When water levels rise above normal summer level masters should be aware of:

Navigation

Navigation marks will have reduced height above the water level or may disappear underwater altogether making the navigable channel difficult to discern.

In narrow sections of the navigations water levels will tend to rise more quickly than in main streams and air draft at bridges will likewise be reduced.

There will also be increased flow rates particularly in the vicinity of navigation infrastructure such as bridges, weirs, locks etc where extra care in manoeuvring vessels will be required.

Harbours and Jetties

Due care is required in harbours and at slipways when levels are at or near the same level as the harbour walkways' as the edge will be difficult to discern especially in reduced light conditions. It is advised that Personal Flotation Devices be worn if tending to craft in a harbour in these conditions.

Slipways

Slipways should only be used for the purpose of launching and recovering of water craft or other objects from the water. Before using a slipway it should be examined to ensure that the surface has sufficient traction/grip for the intended purpose such as launching a craft from a trailer using a vehicle, that there is sufficient depth of water on the slipway to float the craft off the trailer before the concrete apron ends and that the wheels of the trailer do not drop off the edge of the slipway. That life-saving appliances are available in the vicinity, that the vehicle is roadworthy and capable of coping with the weight of the trailer and boat on the incline. It is recommended that slipway operations are conducted by two persons.

Caution to be Used in Reliance upon Aids to Navigation

The aids to navigation depicted on the navigation guides comprise a system of fixed and floating aids to navigation. Prudent mariners will not rely solely on any single aid to navigation, particularly a floating aid to navigation. With respect to buoys, the buoy symbol is used to indicate the approximate position of the buoy body and the ground tackle which secures it to the lake or river bed. The approximate position is used because of the practical limitations in positioning and maintaining buoys in precise geographical locations. These limitations include, but are not limited to, prevailing atmospheric and lake/river conditions, the slope of and the material making up the lake/river bed, the fact that the buoys are moored to varying lengths of chain, and the fact that the buoy body and/or ground tackle positions are not under continuous surveillance. Due to the forces of nature, the position of the buoy body can be expected to shift inside and outside the charted symbol.

Buoys and perches are also moved out of position or pulled over by those mariners who use them to moor up to instead of anchoring. To this end, mariners should always monitor their passage by relating buoy/perch positions with the published navigation guide. Furthermore, a vessel attempting to pass close by always risks collision with a yawing buoy or with the obstruction that the buoy or beacon/perch marks.

Masters of Vessels are requested to use the most up to date Navigation guides when navigating on the Inland Waterways.
