Following the cancellation of Cork Week 300, ICRA has decided to combine the National Championships with this year’s WAVE regatta which will take place at Howth Yacht Club from September 11-13th.

The decision was taken by unanimous vote by all the cruiser-racer representative Board Members at a strongly attended ICRA (remote) meeting this week, with the full support and backing of the RCYC Cork Week team.

The decision took into account a number of factors, including the desire to ensure that the event took place if at all possible and was not cancelled again, the costs and implications of running a standalone event at this stage and the understanding of ensuring boats and crews had some possible opportunity to get up to speed before the event.

The meeting chaired by Commodore Richard Colwell included Cxema Pico, RIYC; David Cullen, HYC; John Leech, LDYC; Ric Morris, RIYC; Johanna Murphy, GISC & SCORA; Peter Ryan, NYC; Denis Byrne, RCYC; Liam Lynch, TBSC. Brian Raftery of SBSC was absent.

The ICRA Committee also say they wish 'to thank generous offers from other clubs to host the regatta on alternate dates'.

Commodore Richard Colwell commented “The ICRA Committee is saddened that the efforts of Cork Week cannot come to fruition so we have considered several alternative options for our annual ICRA National Championships. It was agreed that it would be prudent in the current environment, to delay the important National Championship regatta until as late as possible to try and ensure it goes ahead this year, so we have taken up the offer from Howth Yacht Club to combine the event with the WAVE regatta in September.”

"it would be prudent in the current environment, to delay the important National Championship regatta until as late as possible"

WAVE Chairman, Brian Turvey added “Our team in Howth is delighted to be able to lend support to ICRA for their 2020 Championships. Wave Regatta provides a relatively simple integration for the ICRA Nationals with much of the fleet already intending to compete and at a time of the year which suits many classes for their annual championships, not least that we are hopeful that the pandemic will have abated by then.”

Due to the uncertainty of which events will proceed, it has also been decided to cancel the original Boat of the Year schedule of races and keep under review.

Once we get clarity on what events will be proceeding, we will reissue a revised Notice of Race, ICRA spokesman Dave Cullen said.

#RecordWave - Nineteen metres is the height of what’s being called the world’s largest wave, recorded recently off the North West Coast of Ireland.

Independent.ie reports on the record-breaking swell detected by a weather buoy in the North Atlantic between Ireland and Iceland, following what the World Meteorological Organization’s (WMO) Commission for Climatology described as a “very strong” cold front that passed through at more than 80km per hour.

WMO Assistant Secretary-General Wenjian Zhang said: ”This is the first time we have ever measured a wave of 19 metres. It is a remarkable record.”

The new measurement beats the previous record of 18.275 metres recorded in the North Atlantic nine years ago.

But while the news is causing gasps around the internet, for some it only confirms what’s long been known — that Ireland is on the doorstep of a big wave paradise.

Indeed, Ireland’s North West is no stranger to monster swells, with the giant surf offshore from Mullaghmore in Co Sligo a well-kept secret among the big wave surfing fraternity.

The dangers of winter storms and the risk posed by freak waves are illustrated on the beach of Porsguen near to Portsall in Western France when a retired couple are swept away this month.

It is understood the couple survived the ordeal and rescued by coastal walkers.

The edge of the sea seems to be far enough away for the three people in this clip to be safe – but they are soon to learn that it isn’t.

A large wave crashed onto shore, knocking a pensioner to the floor. First his wife tries to save him before she too loses her footing and ends up being washed out.

The video was shot on the coast of France near Porsguen and uploaded onto YouTube by Olivier Lou who thanked locals Denise and Herve for giving them dry clothes.

#castletownbere – The Department of Transport, Tourism and Sport has been advised that a wave measuring device has been installed on the seabed, adjacent to the Walter Scott Rock, at co-ordinates Latitude 51° 38' 33.6"N, Longitude 009° 54' 20.4"W. A yellow floating marker buoy with a special mark beacon has been installed to indicate the location of the device.

The wave study is being carried out by the Marine Engineering Division of the Department of Agriculture, Food & the Marine. The study is expected to be on-going until late March 2015, weather permitting.

For safety reasons, mariners are requested to keep a sharp lookout and to proceed slowly and with extreme caution in the vicinity of the Walter Scott Rock.

For safety reasons, fishermen are requested to avoid dredging at the co-ordinates mentioned above. Fisherman should take great care when dredging near this location and keep a wide berth from the device which is located on the seabed.

#wave – A new maximum wave height measuring nearly 80–feet (23 metres) has been recorded in weekend storms off the coast of Ireland.

Monster waves the height of five double deck buses occurred during last weekend's ferocious storms off the coast of Donegal, the worst for 30 years, according to Donegal news sources.

The M4 weather buoy, located off the Northwest coast, recorded a new maximum individual wave height of 23.4 metres at 15.00 on Sunday 26th January 2014 during the weekend storm that prompted an orange alert by the Coast Guard.

The new wave measurement easily surpasses the previous record of 20.4 metres at the same location in December 2011, according to Met Eireann.

The M4 buoy is one of a new generation of weather buoys with the ability to measure maximum wave height as well as the more usual Significant Wave Height.

The Significant Wave Height is defined as the average height of the highest one-third of the waves and that is what our forecasts of wave height refer to.

In general, the highest wave of all will be about twice the Significant Wave Height.

There was also a record for maximum significant wave height for the M4 buoy of 15.3m at the same time, with the previous record being 14.7m. The all-time record for Significant Wave Height still rests with the M6 buoy of 17.2m.

#SURFING - British surfer Jayce Robinson wasn't about to let the largest wave ever recorded off Ireland's shores go by without giving it a shot.

And as Sky News Online reports, he was captured doing exactly that on Tuesday afternoon.

The Cornish surfing pro told the website: "It was definitely the biggest barrell I've ever surfed.

"I was a little nervous but I didn't have time to think about it - it's almost like a car crash, you don't know what's happening."

Robinson rode the giant wave for 20 seconds before the lip crashed down and knocked him off his board.

His surfing partner Lyndon Wake, who towed him to the swell at Mullaghmore Head, said: "It's always a worst case scenario when your tow partner wipes out. Lucky he managed to come out the other side OK."

As previously reported on Afloat.ie, storm force winds off the coast of Donegal produced monster rollers of over 20 metres (over 60 feet) in height detected in Donegal Bay.

Mullaghmore Head will once again welcome the world's top big wave surfers for the second annual Tow-In Surf Session in the New Year.

#WAVE – The biggest ever wave in Irish waters was recorded yesterday when storm force winds off the Coast of Donegal produced monster rollers of over 20 metres (over 60 feet) in height off the Northwest tip of Ireland. At least two giant waves put meterologists on alert yesterday prompting the Coastguard to issue a weather warning.

The 20.4 metre wave was detected in Donegal Bay by the M4 weather buoy, according to Met Eireann. The wave was recorded at 2pm yesterday.  (Tuesday 13th December 2011),

Meteorologists said sea conditions, about 60 miles out to sea, were the most serious they had ever experienced. The Irish Coastguard said they had recorded winds of up to 140km per hour off the north-western coast yesterday and issued a warning.

The M4 weather buoy is located 75km north of Belmullet on the north west coast of Ireland. The M4 buoy forms part of the Irish Weather Buoy Network which began in 2000 and is funded by the Department of Transport, Tourism and Sport and run by the Marine Institute in collaboration with Met Eireann and the UKMO.

"This is the largest wave measured on the Weather buoy network to date. However, these recordings are a result of the next generation buoy which was deployed last year. Historically, only the significant wave height could be measured by the older buoys, where heights of between 10 and 13 meters were typically recorded around the coast during winter. The next generation buoys allow us to record and transmit both significant wave height and maximum wave heights as part of our hourly observations," explains Sheena Fennell, oceanographer with the Marine Institute.

Over the last number of years the network has been going through a transitional phase replacing the older models with next generation buoys supplied by Fugro Oceanor. The combination of high quality real time measurements coming from the offshore buoys and coastal systems, coupled with the mathematical forecasting models, is extending the well proven ability of scientists and engineers to accurately forecast the atmospheric conditions and sea state of the ocean.

"With the development in technology we are now able to record maximum wave heights which the older style buoys couldn't do. This parameter will form an important part of forecasting as we move forward." Sheena Fennell further said.

Met Eireann say the stormy conditions will gradually ease off tonight, but then frost and icy patches will develop. However it will remain very windy for a time early tonight, with severe southwest to west gales.

Spectacular photographs taken from the shore by Lifeboat Operations Manager John Brittain during Clifden RNLI's special surf training recently on Dunloughan beach show the type of conditions that volunteer lifeboat crew train in for the life-saving charity. The shots capture the inshore lifeboat crewmembers climbing a wave and exercising in some choppy conditions.

John organised the training in response to the increased popularity of the area with surfers.  RNLI Divisional Assessor Trainer Helena Duggan travelled to the lifeboat station to put 18 volunteer lifeboat crew through their paces and train them in handling the lifeboat in surf and responding to potential callouts from leisure marine enthusiasts.

Training is a core part of volunteering with the RNLI and each crewmember in Clifden trains once a fortnight on the stations two inshore lifeboats.

Commenting on the exercise John said, "I took my camera down to photograph the exercise and was really pleased with the results.  It is great to be able to show the public what our lifeboat volunteers go through to ensure they are fit and trained to go to sea. We had a fantastic turnout on the day and the lifeboat crew learned about boat handling in surf conditions. We are delighted so many people are visiting the area for leisure marine activities."

A US renewable energy company is proposing to meet the Government’s target of generating 500 megawatts of electricity from ocean energy systems by 2020, holding out the possibility of generating tens of thousands of jobs in Ireland. Frank McDonald's story in the Irish Times this morning is here.

For all you need on the Marine Environment - covering the latest news and updates on marine science and wildlife, weather and climate, power from the sea and Ireland's coastal regions and communities - the place to be is Afloat.ie.

Coastal Notes

The Coastal Notes category covers a broad range of stories, events and developments that have an impact on Ireland's coastal regions and communities, whose lives and livelihoods are directly linked with the sea and Ireland's coastal waters.

Topics covered in Coastal Notes can be as varied as the rare finding of sea-life creatures, an historic shipwreck with secrets to tell, or even a trawler's net caught hauling much more than just fish.

Other angles focusing the attention of Coastal Notes are Ireland's maritime museums, which are of national importance to maintaining access and knowledge of our nautical heritage, and those who harvest the sea using small boats based in harbours where infrastructure and safety pose an issue, plying their trade along the rugged wild western seaboard.

Coastal Notes tells the stories that are arguably as varied as the environment they come from, and which shape people's interaction with the natural world and our relationship with the sea.

Marine Wildlife

One of the greatest memories of any day spent boating around the Irish coast is an encounter with Marine Wildlife. It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. And as boaters fortunate enough to have experienced it will testify, even spotting a distant dorsal fin can be the highlight of any day afloat. Was that a porpoise? Was it a whale? No matter how brief the glimpse, it's a privilege to share the seas with Irish marine wildlife.

Thanks to our location in the North Atlantic, there appears to be no shortage of marine life to observe. From whales to dolphins, seals, sharks and other ocean animals, the Marine Wildlife category documents the most interesting accounts around our shores. And we're keen to receive your observations, your photos, links and video clips, too!

Also valuable is the unique perspective of all those who go afloat, from coastal sailing to sea angling to inshore kayaking to offshore yacht racing, as what they encounter can be of great importance to organisations such as the Irish Whale and Dolphin Group (IWDG). Thanks to their work we now know we share the seas with dozens of species who also call Ireland home. But as impressive as the list is, the experts believe there are still gaps in our knowledge. Next time you are out on the ocean waves, keep a sharp look out!

Weather

As an island in the North Atlantic, Ireland's fate is decided by Weather more so than many other European countries. When storm-force winds race across the Irish Sea, ferry and shipping services are cut off, disrupting our economy. When swollen waves crash on our shores, communities are flooded and fishermen brace for impact - both to their vessels and to their livelihoods.

Keeping abreast of the weather, therefore, is as important to leisure cruisers and fishing crews alike - for whom a small craft warning can mean the difference between life and death - as it is to the communities lining the coast, where timely weather alerts can help protect homes and lives.

Weather affects us all, and Afloat.ie will keep you informed on the hows and the whys.

Marine Science

Perhaps it's the work of the Irish research vessels RV Celtic Explorer and RV Celtic Voyager out in the Atlantic Ocean that best highlights the essential nature of Marine Science for the future growth of Ireland's emerging 'blue economy'.

From marine research to development and sustainable management, Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. Whether it's Wavebob ocean energy technology to aquaculture to weather buoys and oil exploration, the Marine Science category documents the work of Irish marine scientists and researchers and how they have secured prominent roles in many European and international marine science bodies.

Power From The Sea

The message from the experts is clear: offshore wind and wave energy is the future. And as Ireland looks towards the potential of the renewable energy sector, generating Power From The Sea will become a greater priority in the State's 'blue growth' strategy.

Developments and activities in existing and planned projects in the pipeline from the wind and wave renewables sector, and those of the energy exploration industry, point to the future of energy requirements for the whole world, not just in Ireland. And that's not to mention the supplementary industries that sea power projects can support in coastal communities.

Irish ports are already in a good position to capitalise on investments in offshore renewable energy services. And Power From The Sea can even be good for marine wildlife if done properly.

Aside from the green sector, our coastal waters also hold a wealth of oil and gas resources that numerous prospectors are hoping to exploit, even if people in coastal and island areas are as yet unsure of the potential benefits or pitfalls for their communities.

Changing Ocean Climate

Our ocean and climate are inextricably linked - the ocean plays a crucial role in the global climate system in a number of ways. These include absorbing excess heat from the atmosphere and absorbing 30 per cent of the carbon dioxide added to the atmosphere by human activity. But our marine ecosystems are coming under increasing pressure due to climate change.

The Marine Institute, with its national and international partners, works to observe and understand how our ocean is changing and analyses, models and projects the impacts of our changing oceans. Advice and forecasting projections of our changing oceans and climate are essential to create effective policies and management decisions to safeguard our ocean.

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is fundamental to life on earth and affects so many facets of our everyday activities. One of the greatest challenges we face as a society is that of our changing climate. The strong international collaborations that the Marine Institute has built up over decades facilitates a shared focusing on our changing ocean climate and developing new and enhanced ways of monitoring it and tracking changes over time.

“Our knowledge and services help us to observe these patterns of change and identify the steps to safeguard our marine ecosystems for future generations.”

The Marine Institute’s annual ocean climate research survey, which has been running since 2004, facilitates long term monitoring of the deep water environment to the west of Ireland. This repeat survey, which takes place on board RV Celtic Explorer, enables scientists to establish baseline oceanic conditions in Irish waters that can be used as a benchmark for future changes.

Scientists collect data on temperature, salinity, water currents, oxygen and carbon dioxide in the Atlantic Ocean. This high quality oceanographic data contributes to the Atlantic Ocean Observing System. Physical oceanographic data from the survey is submitted to the International Council for the Exploration of the Seas (ICES) and, in addition, the survey contributes to national research such as the VOCAB ocean acidification and biogeochemistry project, the ‘Clean Atlantic’ project on marine litter and the A4 marine climate change project.

Dr Caroline Cusack, who co-ordinates scientific activities on board the RV Celtic Explorer for the annual survey, said, “The generation of long-term series to monitor ocean climate is vital to allow us understand the likely impact of future changes in ocean climate on ecosystems and other marine resources.”

Other activities during the survey in 2019 included the deployment of oceanographic gliders, two Argo floats (Ireland’s contribution to EuroArgo) and four surface drifters (Interreg Atlantic Area Clean Atlantic project). The new Argo floats have the capacity to measure dissolved ocean and biogeochemical parameters from the ocean surface down to a depth of 2,000 metres continuously for up to four years, providing important information as to the health of our oceans.

During the 2019 survey, the RV Celtic Explorer retrieved a string of oceanographic sensors from the deep ocean at an adjacent subsurface moored station and deployed a replacement M6 weather buoy, as part of the Irish Marine Data Buoy Observation Network (IMDBON).

Funded by the Department of Agriculture, Food and the Marine, the IMDBON is managed by the Marine Institute in collaboration with Met Éireann and is designed to improve weather forecasts and safety at sea around Ireland. The data buoys have instruments which collect weather and ocean data including wind speed and direction, pressure, air and sea surface temperature and wave statistics. This data provides vital information for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research.

“It is only in the last 20 years, meteorologists and climatologists have really began to understood the pivotal role the ocean plays in determining our climate and weather,” said Evelyn Cusack, Head of Forecasting at Met Éireann. “The real-time information provided by the Irish data buoy network is particularly important for our mariners and rescue services. The M6 data buoy in the Atlantic provides vital information on swell waves generated by Atlantic storms. Even though the weather and winds may be calm around our shores, there could be some very high swells coming in from Atlantic storms.”
