Those who have been rewarded for their careful adherence to social distancing and crew-pod rules by getting some sailing in the Indian summer which has been at its very best on Cork Harbour can be forgiven for wondering if, despite all their precautions, they've been afflicted by a mild bout of double vision.

For if you've been sailing down off Crosshaven, now and again you'll see this pretty little transom-sterned dark blue sloop with a nice crisp suit of new sails, out happily slicing her way with very little fuss across the blue water, her general appearance exuding quality construction, and her lone helmsman very deservedly the monarch of all he surveys.

Yet if you're sailing further up the harbour off Monkstown on a somewhat similar day – for they seem to have had them in profusion – you'll have seen what looks to the casual observer to be the same boat, yet how does she seem to have two totally different home berths?

The up-harbour boat we featured here on August 14th, and she is, of course, Pat Murphy's Kinsale-built (in 1952) Colleen 23 class Pinkeen, beautifully brought up to condition by a combined effort by Pat and Jim Walsh of Walsh Boat Works in Nohoval.

But the other boat – whose differences any dedicated aficionado can spot immediately – is a sort of nautical trompe l'oeil, as she's a complete re-working of a well-used but still sound fibreglass hull through the special genius of Bill Trafford of Alchemy Marine in Doneraile in North Cork order to create something else altogether.

Like many, Crosshaven sailor Philip Brownlow has the fondest memories of the three Alan Buchanan-designed Colleens which used to be based in Kinsale, where they'd been inaugurated by Nolly Stokes and John Thuillier. But while he wanted the spirit of the Colleens, he didn't want the demands of the continuous maintenance of an all-wooden boat, so he set Bill the challenge of re-purposing some other class's fibreglass hull to capture the Colleen essence, and Bill reckoned he could make the hull of a Kim Holman-designed Elizabethan 29 do the job, and this was how it was done. Nobody involved in the project makes claims that this is a Colleen 23. But they rightly believe that she captures the bright spirit of the Colleen 23, so maybe we should simply call her the Colleen 27.

If you see Pat Murphy's Pinkeen and Philip Brownlow's Sunflower side-by-side, it's easy to spot the differences – not least because of the size gap – yet equally, the shared spirit shines through.

But if you happen to see them at two different times in different places in the harbour on the same day, confusion is understandable. As one occasional sailor put it: "The only way I know which is which is because one helmsman wears a Jack Charlton cap, and the other doesn't."

Bill Trafford of Alchemy Marine, hidden away in the farmland of Skenakilla west of Mitchellstown in north County Cork, has carved himself a unique reputation in recent years for successfully re-imagining glassfibre boats of a certain age, and transforming them into modern classics writes W M Nixon.

In fact, calling them “boats” at a key stage of this process is scarcely accurate. What arrives in his shed as a former but still recognisably standard sailing craft quickly becomes no more than “the donor boat”, which is soon a bare hull with which Bill is free to play, re-tweaking the sheerline, altering the stern, and adding a completely new deck and coachroof configuration

That’s just for starters. But with the former Elizabethan 23 Kioni, and more recently the former Etchells 22 Guapa, the process is indeed magic, because both boats have ultimately emerged as beautiful head-turners wherever they sail.

But while he was given a lot of freedom in making choices with those boats, Bill’s main project this winter is for a very specific project.

Back in 1950, some members of the Royal Cork YC commissioned a boat from up-and-coming yacht designer Alan Buchanan. They wanted a miniature yet classically stylish performance cruiser, just 23ft 2ins LOA, to be called the Colleen and capable of being built locally.

The 1950s were very far from being a boom time in Ireland, so it seems that no more than four were built. But one or two are still about, and a contemporary Cork Harbour sailor fancies the look of them, but doesn’t fancy the hassle of maintaining a wooden hull.

So now Bill Trafford faces the challenge of creating a new Colleen from a glassfibre hull donated by some other boat. He quickly realised that the Buchanan-designed glassfibre Halcyon 27 – which has a transom stern – was otherwise unsuitable, so he settled on the Elizabethan 29, designed by Kim Holman and built with great success by Peter Webster in Lymington in the 1950s.

 He found one in giveaway terms on ebay in the middle of England at Milton Keynes, and Jonathan Kennedy of Kennedy Boat Haulage personally undertook the long trek to move the little boat from a neglected condition in the middle of England to a winter of transformation in the middle of Munster.

Having seen what Bill Trafford has been able to do with a former Elizabethan 23 and a former Etchells 22, there’s no need to doubt that the spirit of the Colleen will be re-captured in that secret laboratory near Skenakilla Cross-roads. And those of us who feel that the vigorous sheerline of the original might have been better if it had the lowest point slightly further aft may even be indulged in our views. But that of course is up to the owner, who has greatly brightened the prospects of the winter by commissioning this fascinating project

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.
