Multiple champion Tim Goodbody's retirement from the Sigma 33 class was saluted at a packed Royal Irish Yacht Club on Friday night when class captain Paddy Maguire honoured the stalwart with an 'Excellence Award' setting out his achievements over 16 years in the one design keelboat class.

In 1999, Goodbody bought his Sigma 33 White Mischief. He was joined by two of his crew that had sailed with him previously, namely Paul McCarthy and Brendan Farrell and was joined by Patrick Cafferky, Paddy Boyd, David Crawford and Richard Cotton to form the basis of the new crew.

From 1999 to the current season they won the UK National Championships, the Irish Championships and all of the club prizes in Dublin Bay Sailing Club (DBSC). They also achieved podium finishes in many other events. Of all races that Tim and the White Mischief crew competed in, Maguire estimated they won '75% of all races sailed; an extraordinary achievement'.

'This performance record clearly demonstrates an exception level of ability and sailing skills that are so rarely if ever achieved in a One Design Class. More importantly it was achieved on a consistent basis throughout', Maguire told the class.

It is the second honour for Goodbody in as many weeks. Last weekend DBSC honoured the Dun Laoghaire sailor at its prizegiving when it uniquely captured Goodbody, his son and grandchildren all as annual prizewinners in Ireland's biggest sailing league.

86 members were in attendance for the prizegiving including no less than five Commodores and the Chairman of Sigma 33 Class Paul Prentice.

The prizes were awarded to :

White Mischief : Tim Goodbody : Sigma Model : Best of Sigma qualities
Leeuwin: Henry Leonard & Bobby Kerr : Corinthian Qualities
Rupert: Dick & Philip Lovegrove : September Series Winner

#dlregatta – The Sigma 33 class has announced its Irish National Championships 2015 will be held in conjunction with Volvo Dun Laoghaire Regatta from 9th to 12th July 2015. The regatta is likely to be the biggest Sigma Class event of 2015, accordiong to class captain Paddy Maguire. 'To date there is a very strong entry of seven visiting crews which with the local fleet brings the total entry so far to 16', he told Afloat.ie. This – to date – is the biggest entry of one design cruisers for the 400–boat biennial regatta.

#sigma33 – The Sigma 33 Class on Dublin Bay will race in Cruisers 2 for the first time in 15 years it has been confirmed by Sigma 33 class captain Paddy Maguire.

The Sigma's will receive results in 2015 as one design, IRC and echo which will add a variety to their racing and prove a great challenge for both Sigmas and Cruisers 2 alike.

In November 2014 the Class proposed to DBSC that the Sigma 33 would race in Cruisers 2 for 2015 and this was accepted by DBSC. The reason for the change was to provide a more enjoyable and completive racing by sailing ng against more boats in a bigger fleet. The new Cruisers 2 fleet for 2015 will be one of the biggest keel boat fleets in Dun Laoghaire with approximately 25 Boats.

To compete in 2015 in the Cruisers 2 the Sigma's will have to improve their performance on the water. To this end they have developed a very attractive sailing programme for the season including a Coastal race, Ladies race and a ballet race to name but a few. The new programme of events will be launched this Friday 6th March at the National Yacht Club with a Sailing supper and talk by Prof O'Connell "HOW TO IMPROVE YOUR RESULTS BY 20% in 2015" to a full house.

One of the other big challenges is to increase the number of crew both male and female as part of the process of improving the individual boat performance.

Donald McClaren sailing Sigmatic won the UK Sigma 33 British Championships on the home waters of the Northern Clyde at the weekend (June 21-23) with Dublin Bay's Tim Goodbody fourth overall in the 18–boat fleet at Helensburgh, Scotland.

Ten races were sailed according to the latest (and poorly presented) results on the Helensburgh Sailing Club website here

Three local Bangor boats, joined 15 others from all over the United Kingdom and Ireland for the Sigma 33 OOD Class Championships in Helensburgh, Scotland from 21-23 June. The boats and crews were treated to incredibly tight racing in the full range of Scottish summer weather; flat calms and scorching sun to driving rain and screaming winds! All spliced together with a warm and sociable welcome from Helensburgh Sailing Club and the Sigma fleet. The members of both former and latter enjoying much discussion of the new trial sails, with both results and conjecture indicating it's the crews not the sails that make the difference.

Despite the changeable weather, all ten races were completed and following the successes of the Royal Ulster/ Ballyholme fleet at the Irish Championships all three crews put in strong performances. Sula (D&E Taylor and crew), showed fantastic speed through out the event but suffered at the hands of some unfortunate start line incidents. Despite this they fought back to record multiple top 5 results and win the Silver fleet. Cariad (G Bell and crew), showed why they are never far off the pace at any event and at times were resurgent right at the front of the fleet fighting it out for line honours finishing a credible 7th overall. They were beaten only by local boats savvy to the complex tides of the race area, ten times Irish Champions White Mischief (T Goodbody and crew) from Dublin and newly crowned Irish Champions for 2013, Squawk (P&E Prentice and crew.) Squawk had a consistent regatta collecting multiple top 3 results, including two race wins. Leading by one point going into the last race fell at the final hurdle to finish 3rd Overall, drawn down the fleet by a single result in double figures.

The reigning Class Champion Sigmatic (D Mclaren and crew) won the event with as much flare and passion as they put into organising it. Whilst another boat local to Helensburgh, Close Encounters (G Whyte and crew) sailed a phenomenally consistent event to finish second just two point adrift.

1st Sigmatic (D McClaren and crew), 2nd Close Encounters (G Whyte and crew), 3rd Squawk (P Prentice and crew), 4th White Mischief (T Goodbody and crew), 5th Leaky Roof II (A Harper and crew). The class looks forward to joining South Caernarvonshire Yacht Club, Abersoch in June 2014 for the next class championship.

A fortnight ago, Dublin Bay's only entrant in the Royal Ulster YC hosted Irish Sigma 33 Championships in Bangor from 7th–9th June 2013 was past champion, Goodbody.

The White Mischief crew from the Royal Irish YC crew were fourth from a disappointing turnout of eight boats for the ten race series.

The Irish championships was won by Royal Ulster's Squawk sailed by Paul Prentice and followed by Elaine and David Taylor's Sula. Third was Signet of Kip (P Martin) from Strangford.

#sigma33 – Not even a judge from the 'Dragon's Den' TV show could stop a Scottish crew from claiming the class Sigma 33 title on Dublin Bay at the weekend. SCROLL DOWN FOR FULL RESULTS SHEETS AND PHOTOS BELOW.

Sailed in a range of both heavy and light conditions defending champion (and the championship host) Tim Goodbody of the Royal Irish Yacht Club lost his title but finished top Dublin Bay boat in third place as Clyde visitor Donald McLaren's Sigma 33 'Sigmatic' emerged as the clear winner.

Fifty knot gusts cancelled Friday's opening two races but Race officer Brian Mathews completed the schedule by setting four races still in blustery conditions on Saturday. A further three races were held yesterday.

Regular Sigma 33 sailor Bobby Kerr, a judge on the TV Business show Dragon's Den, was one of 24 boats competing in what was the biggest Sigma 33 event for a decade.

'Leaky Roof', Alan Harper also from the Clyde was second.

The overall winner Sigmatic

Goodbody's White Mischief also won the Irish Sigma Championships with Sula from Bangor in second place.

Sunday dawned a lovely clear day with steady westerly winds of 15 knots gusting 20 making a difficult choice as the whether a No 1 or No 2 was the correct headsail choice with the fleet evenly divided.

Race Officer Jack Roy set perfect starting lines of the correct length with a first windward leg of 1.3 miles and so the faster yachts had time to benefit from any speed advantage and they came to the front consistently. Most results came down to establishing an overlap at the last leeward mark with the top 5 or 6 boats crossing the finishing line closely packed followed by the rest of the fleet competing for their places.

The "Silver" fleet was won by Dick Lovegrove's Rupert with Dermot Clarke and Paddy Maguire's Gwilli Two in second place.

This was a competitive weekend's racing in Dublin Bay and the willingness of competitors to take penalty turns demonstrated a knowledge of the rules and desire to abide by them. This all added to achieving a competitive and friendly regatta which was enjoyed by all.

#sigma33 – The Sigma 33 class has attracted the highest entry for over a decade for it's national championships on Dublin Bay at the weekend with competitors arriving from across the Irish sea from Scotland, Belfast Lough, Strangford Lough, Liverpool, Abersoch, Plymouth, Kinsale as well as a strong local DBSC contingent.

(Post regatta results, report and photos here)

The Royal Irish Yacht Club (RIYC) is hosting the 20-boat event from Friday through to Sunday.

This strong entry underlines the popularity of this seaworthy One Design offshore racing yacht which enjoys strong one design racing in so many centres as well as being very competitive under IRC.

The Championship offers competitors a choice of windward leeward, Olympic type and "round the cans" courses in Dublin Bay under the expert guidance of Principal Race Officer Jack Roy who will be setting courses at the Olympic Games in Weymouth next month.

The defending Class and Irish Champion is Tim Goodbody's White Mischief and they can expect strong competition from previous Champions such as Sigmatic from the Clyde as well as from many other visiting and local yachts including the Bay's own Gwilli Two skippered by Paddy Maguire.

The fifth "Nora Barnacle Challenge" takes place this year on Friday 20th August 2010 at 4p.m. in Dublin Bay. The event is a charity yacht race sailed in 11 Sigma 33 boats. The purpose of the race is to raise funds for the Blackrock Hospice. The event is run by 3 Sigma 33 sailors, Bobby Kerr, Paul McCarthy and Maurice Byrne - in association with their local pub "Fitzgerald's of Sandycove". The idea is to provide an opportunity to non-sailors to participate in a short race from Dun Laoghaire to Dalkey and back with the assistance of two experienced sailors.

This year it is expected that there will be over 100 participants sailing on the water. All the proceeds raised for the event are donated to the Blackrock Hospice charity to provide funding for much needed equipment. This event brings together the Sigma 33 sailors in Dun Laoghaire , the traders of Sandycove and Glasthule and the 100 plus participants who together provide the sponsorship and donations for this deserving charity.

This is the fifth year of the event and it is hoped that by Friday evening the group will have raised €75,000 since 2006 for the Hospice through donations and sponsorship raised by participants.

The Nora Barnacle challenge started in 2006 when three local sigma 33 sailors were challenged by the local cliental of Fitzgerald's pub in Sandycove, to settle a score "who was the best sigma sailor in the establishment". The challenge was accepted and the event was organised by the three sailors, Bobby Kerr of "Leeuwin", Paul McCarthy of "White Mischief" and Maurice Byrne of "Miss Behavin". To ensure fair play and that no one boat would have a competitive advantage the rules of the event stated that five members of the crew of each boat would be made up from people with no sailing experience, along with two experienced sailors and that the race would be used as an opportunity to raise sponsorship in aid of the designated charity, the Blackrock Hospice.

In keeping with tradition, all participants, spectators and supporters will retire to Fitzgerald's pub in Sandycove for refreshments and the official prize giving of "The Nora Barnacle Cup" presented by Tom Fitzgerald followed by the annual auction to raise additional funds. The official " Nora Barnacle Challenge" T-Shirt will also be on sale.

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.
