With the recent series of storms model yacht racers had to cancel a number of events but a few managed to get on the water. We had a friendly outing in Gortin lake in November and another one on Lough Erne last weekend writes Gilbert Louis.

One of the main comments about these 2 outings is that most of the boats that you see in the pictures and videos are home built. Most of these wooden boats were built by Neill Suitor a sailing enthusiast from Northern Ireland who clearly has ‘golden fingers’ to build these beauties. Having said this, others also built their own boat. Trevor Fisher and Bob Wells also from Northern Ireland built a Goth XP design in wood. Des Dwyer and Sephen Fay from Dublin built an Alternative design… (Alternative is the actual name of the boat design. This boat was designed by Brad Gibson).

The IOM class is not a one design but a box rules where the rigging is pretty much one-design but the class rules allow for creativity and designs opportunity with the hull. This ensure evolution of the class while keeping the cost down and all boats racing competitively together. 

This allows home designs and home built boat to be as competitive as series built fiberglass boats and this is a really good thing.

Brad for example who’s multiple world and European champion designs and builds his own boats and his sails. One of the successful German skipper also designed and built his own boat, sails and even his rigs with wooden rigging with pre-bend in them. While this amateur building is still a minority amongst IOM skippers it shows that whether you buy a ‘production’ boat or build it yourself you can be competitive in the class.

I race with a wooden boat designed by Frank Russell, a well-known model boat designer from Australia (http://www.frankrusselldesign.com/) which was built by Neill Suitor. I finished 5th in national regatta in France in Autumn last year with it. I was the only competitor there racing a wooden boat but I was racing against all the latest designs (Britpop, V8, V9, Fraktal, MX, cheinz, etc…).

The Irish fleet is currently enjoying growth in the Cork region and in Northern Ireland at the moment which is encouraging.

In Dublin, Howth YC which is a great base for the Dublin fleet is hosting the regular Winter and Spring series with events every 2 weeks.

Looking forward to see you on the water! Or rather ashore with us to control your boat ;-)

#modelboats – Despite an uneasy weather forecast and torrential rain during the week model boat skippers heading for the Ulster IOM championships just couldn't complain about the weekend as we had light wind, a good few sunny spells and no rain at all writes Gilbert Louis.

With this in mind we had more skippers than last year's Ulster's championships. They came from the Republic, Northern Ireland, Scotland and England, 18 in total.

Saturday saw the whole fleet of 18 boats sailing together. Despite talks of splitting into 2 fleets the decision was made to keep us all in one fleet which has one key advantage. We get twice as many race and time on the water and this is part of sailing.

The format was sets of 3 races pretty much back to back with only a few minutes for skippers to make adjustments if needed between the races, to tune their boats to the conditions. Or giving an opportunity for quick fixes in case of brakeage.

Then a longer break before the next set of 3 races. This format allowed us to spend great time on the water and get the most of the day sailing not watching others sail. Everyone enjoyed it.

Sure it also made for spectacular starts ! 18 boats on the starting line is not something we're used to so you have to be on the first line or you get spat out at the back very quickly after the start. This is excellent training for us as we don't have that experience in Ireland but that's what they do at international levels so a good exposure for us.

The trick is to be amongst the front line of boats in the last few seconds before the start. You need to make your space and defend it. Not easy when you're in your boat, even more difficult when you have your boat in a swarm of other boats all looking to have the perfect start.

The start and first beat to the weather mark will dictate pretty much 70-80% of your race result. It is so much easier to control the fleet from the front then try to sail through it to get there. Particularly when there is very little difference in boat speed. It is too easy when you're behind to say my boat is not as fast as the other at the front but actually I found that my boat speed particularly on the Sunday was very similar to them. So the difference is elsewhere: a good start, clean air, going on the right side, staying clear of contacts and good tacks. Yes the difference will show in making mistake on any of these and at the end when you add all the boat lengths you lost in a bad tack, going the wrong side or worth a bad start and I don't even count getting cought up with other boats, penalties and these add up to several boat lengths and places between you and the first boat.

Jeff Kay from HYC who's our most experienced skipper having competed at several European and World championships was able to use that experience and get great starts and was "fighting" for top 5 places on regular basis.

There were 5 of us coming from the Republic: Jeff and his brother Stephen Kay, both racing the now very popular and successful Britpop designed by Brad Gibson. Then Des and myself sailing a XP designed by Frank Russell, and Oscar, a new addition to our fleet who came to compete for his first ever IOM regatta with my trusty V6 designed by Ian Vickers.

The intensity of the races back to back took its toll on Jeff's back and he had to sit a a number of races despite really good performance on the water.

Stephen did well up until his electric issue started. He got very irregular results due to a random receiver problem which got worse and forced him to abandon the event. A real pity as he also had the pace.

Des struggled on the saturday with his XP, trying to find a good tuning for the light wind conditions and his work paid out as he was right in the fight on day 2.

Gilbert was trying his brand new XP which only touched the water once before for the floatation test so it was very much unknown whether that design could match the reputable speed of the Britpop. Race after race Gilbert fixed a number of teething problems which improved reliability and upwind performance but an alignment problem of the gooseneck forcing the main boom upwards as the sheets were eased, spilling the wind out meant that he coudn't gain places on the downwind legs but was rather loosing some.

On day 2 and a fixed gooseneck Gilbert managed to bring the pace of the boat closer to the best. But the starts were still a problem which coudn't be fixed in tuning. Yet race after race he was working his way up to the front of the fleet and finished on a high as he managed a stunning start of the last race and after good tactical decision led at the weather mark and managed to keep no 46 britpop at bay to lead to the finish. So the XP has potential, more time sailing in different conditions will give us more information on this new design.

Bottom line we still have work to do in Ireland to match the Scots and English but we're making progress which is encouraging. A great meal at Paddy's barn pub put an end to this great event before people left to get their ferry back.

Supporting this event is our repeat sponsor Catsails so thank you Nigel and Sue for your on going support.

Brian O'Neill planned and organised this event with the support of Bill, Ali and others making this year's event another great success. 

Next is the Winter Series in Howth Yacht Club that starts shortly.

#modelboat – The model boat classes have been experimenting with chines for a while now. We have seen a new trend over the recent years in boat designs. This new wave came from the racing boats, TP52, VOR70, and recently making its way to the cruiser racer designs like the new X boats or Malango to name a few.  The funny thing is that not until recently chined boats were still built by amateur builders as they are easier to build. Yet now we are coming back to them, the 10R, A class, Marblehead and also the One Metre class are now coming out with chine.
The IOM or International One Metre Class operates under a box rules format. This, in a nutshell, allows for a relatively open format to boat designs but the rules on the number of rigs and their dimensions are very stricts.
This ensures close racing as we have seen over the years. For the past couple of years the arrival of chines on boat design increased the performance of these boats a notch up. However there are still many debates about the chine and its effect on performance. From what I have seen and tested so far, I can give 3 advantages of the chine design over rounded hulls:
1- the chine helps the boat to accelerate that bit quicker after a tack.
2- It allows to track nicely on the beat versus a rounded hull that would "slide" more as it heels in the gusts.
3- it helps the boat to get planning that little bit earlier and longer on the run
there is a 4th point often discussed within the class. That boats with chines tend to nose dive less in the gusts and accelerate more. I agree to some extend as in my opinion this is primaliry due to more volume in the forward section, complemented by a higher radius of the foredeck to help the come up should it nose dive. I am not of the view that the chine helps here, and the proof is that Brad Gibson who made the most successful chine design, did design another boat before called the SKA which goes well downwind and has no chine.
See the pictures attached to see the difference in designs and even amongst the chined boats, its length, position and angle varies across the design range.
So does that means that rounded boats are passed their due date ? No not at all, not later than a month ago I won an event in Scotland with my 2006 V6 which has a rounded hull, ahead of newer chined boats. There are many other rounded hulls that are at least as successful like the Obsession, the V7 to name a few.
There is it seems a "fashion" trend to go and get a chined boat, but like any other sailing class you can focus on the little things and miss on the big picture. Like getting the tuning of the boat wrong, opting for the wrong rig, an electric failure, a bad start, seaweed in the keel, a wrong tack, overstanding a mark, and the list goes on. One has more to lose in doing any of these errors than not getting a chined boat.

#TITANIC - A replica of the Titanic is at the centre of a High Court dispute between two former partners, as RTE News reports.

Carmel McGrath claims she paid the costs of constructing the 16ft scale replica of the tragic cruise liner, and has secured an injunction preventing Zoltan Panka, a Hungarian national, from selling the €70,000 model after he removed it from her home in the northern suburbs of Cork.

Panka gave a sworn statement to the court disputing the claims of his former partner, alleging he received abusive messages from her after taking the model.

He denies any intention to sell the replica, currently believed to be at a location in Carrigaline, and repudiates the estimated value of McGrath's investment as well as any commercial relationship between the two.

The Hungarian added that model ship building was a family hobby, and that he had put in as much as 2,000 hours' worth of work into the uncompleted project, which was intended to mark the 100th anniversary of the ship's demise.

RTE News has much more on the story HERE.

One of the world's top supermodels, Doutzen Kroes of the Netherlands, is selling her 470 sailing dinghy for charity. Doutzen and her 470 have already become famous in the Douwe Egberts coffee advert which features Doutzen reminiscing over her 470, which she has mainly enjoyed sailing recreationally.

Twenty-six year old beauty Doutzen, who has been the face for many leading consumer brands and fashion houses, has offered her 470 dinghy for the highest bids on the leading Dutch auction website www.marktplaats.nl

Earlier this week, bids of Euros 1,000,000 were made, but as Doutzen recognized in an interview on Radio 538, one of Holland's leading radio stations, "There are bids of Euros 1,000,000 but I think they are not realistic. I have received a serious bid of Euros 20,000. I hope for more people to make a higher bid in favour of Dance 4 life."

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
