#whale – A marine biologist who attempted to cut open a dead Sperm Whale beached in the Faeroe islands last Tuesday (November 26) narrowly escaped being dosed in entrails when the poor dead creature exploded.

A video clip, shown on Faroese Television, showed a washed-up dead sperm whale explode, spraying entrails. The dead whale had been lying on the beach for two days after it got stuck in waters between the Faroe Islands' two biggest islands. On Tuesday, marine biologist Bjarni Mikkelsen was dispatched to cut it open. As he did so, the whale exploded - the explosion being the result of methane gas accumulating during the dying process.

Laast October in Baltimore, West Cork a whale carcass cretaed a 'Rancid Oil Slick' in a conservation area off the south west coast of Ireland after it died in the Baltimore harbour and was towed offshore.

#MarineScience - An American university is teaming up with marine experts in Dingle to offer advanced marine biology classes.

As the Fairfield Sun reports, the biology department at Sacred Heart University in Connecticut is collaborating with scientists and staff at the Dingle Oceanworld Aquarium to offer the advanced classes to undergraduate and postgraduate students alike, beginning this May.

It's expected that the Coastal Study Centre programme will eventually provide both semester-long and short courses to take advantage of the aquarium's advanced research facilities, and will also accommodate students doing relevant thesis field work.

“Very few primarily undergraduate institutions have as strong a coastal focus as Sacred Heart does, which is only enhanced by our proximity to Long Island Sound,” said John Rapaglia, assistant professor of biology at Sacred Heart.

Dingle Harbour’s semi-rural to rural location creates a nice juxtaposition to the highly urbanised Long Island Sound.”

Sacred Heart already has an established campus in the Kerry Gaeltacht town where students can take classes on Irish and Celtic history and heritage among other subjects.

#MARINE WILDLIFE - Work on exterminating sea squirts at a marina in north Wales has begun.

The £250,000 (€301,000) project by the Countryside Council for Wales involves attaching giant bags to the subsurface structures around the marina in Holyhead, which is hoped will stop the clean flow of water to the sea squirts, causing them to suffocate and die.

Marine biologist Rohan Holt, who is managing the project, said: “If we successfully eradicate the sea squirt, we will work hard to make sure that it does not recolonise.

"This will mean careful monitoring in Holyhead marina and other marinas and popular mooring areas throughout Wales to check that it hasn’t reappeared."

The sea creature threatens shellfish by spreading like a blanket across the seabed and other surfaces.

As previously reported on Afloat.ie, colonies of the invasive Japanese sea squirt are posing a throat to mussel and scallop bed in the Menai Strait between Anglesey and the mainland.

Boats from Ireland have been blamed for carrying the invasive pest into Holyhead.

Time may be running out for Scotland's only resident pod of killer whales, the Scotsman reports.
The four males and five females have been studied at their home in the west of Scotland by the Hebridean Whale and Dolphin Trust and the Irish Whale and Dolphin Group for almost 20 years.
The marine mammals have been sighted at various times since 1981 by members of the public in Scotland, Wales and Ireland.
But since 1992 the group - known as the West Coast Community - has failed to produce a single surviving calf.
Marine biologist Dr Andy Foote said: "It's probably too late to save this group. I do believe that they will become extinct in our lifetime which is very regrettable since not many people even know that such a distinctive group of killer whales exist just off our coast."
Dr Foote believes possible contaminants in the waters off Scotland's west coast could be one reason why the pod is not successfully breeding.

Dublin Bay 21s

An exciting new project to breathe life into six defunct 120-year-old Irish yachts that happen to be the oldest intact one-design keelboat class in the world has captured the imagination of sailors at Ireland's biggest sailing centre. The birthplace of the original Dublin Bay 21 class is getting ready to welcome home the six restored craft after 40 years thanks to an ambitious boat building project was completed on the Shannon Estuary that saved them from completely rotting away.

Dublin Bay 21 FAQs

The Dublin Bay 21 is a vintage one-design wooden yacht designed for sailing in Dublin Bay.

Seven were built between 1903 and 1906.

As of 2020, the yachts are 117 years old.

Alfred Mylne designed the seven yachts.

The total voting population in the Republic's inhabited islands is just over 2,600 people, according to the Department of Housing.

Dublin Bay Sailing Club (DBSC) commissioned the boat to encourage inexpensive one-design racing to recognise the success of the Water Wag one-design dinghy of 1887 and the Colleen keelboat class of 1897.

Estelle built by Hollwey, 1903; Garavogue built by Kelly, 1903; Innisfallen built by Hollwey, 1903.; Maureen built by Hollwey, 1903.; Oola built by Kelly, 1905; Naneen built by Clancy, 1905.

Overall length- 32'-6', Beam- 7'-6", Keel lead- 2 tons Sail area - 600sq.ft

The first race took place on 19 June 1903 in Dublin Bay.

They may be the oldest intact class of racing keelboat yacht in the world. Sailing together in a fleet, they are one of the loveliest sights to be seen on any sailing waters in the world, according to many Dublin Bay aficionados.

In 1964, some of the owners thought that the boats were outdated, and needed a new breath of fresh air. After extensive discussions between all the owners, the gaff rig and timber mast was abandoned in favour of a more fashionable Bermudan rig with an aluminium mast. Unfortunately, this rig put previously unseen loads on the hulls, resulting in some permanent damage.

The fleet was taken out of the water in 1986 after Hurricane Charlie ruined active Dublin Bay 21 fleet racing in August of that year. Two 21s sank in the storm, suffering the same fate as their sister ship Estelle four years earlier. The class then became defunct. In 1988, master shipwright Jack Tyrrell of Arklow inspected the fleet and considered the state of the hulls as vulnerable, describing them as 'still restorable even if some would need a virtual rebuild'. The fleet then lay rotting in a farmyard in Arklow until 2019 and the pioneering project of Dun Laoghaire sailors Fionan De Barra and Hal Sisk who decided to bring them back to their former glory.

Hurricane Charlie finally ruined active Dublin Bay 21 fleet racing in August 1986. Two 21s sank in the storm, suffering the same fate as a sister ship four years earlier; Estelle sank twice, once on her moorings and once in a near-tragic downwind capsize. Despite their collective salvage from the sea bed, the class decided the ancient boats should not be allowed suffer anymore. To avoid further deterioration and risk to the rare craft all seven 21s were put into storage in 1989 under the direction of the naval architect Jack Tyrrell at his yard in Arklow.

While two of the fleet, Garavogue and Geraldine sailed to their current home, the other five, in various states of disrepair, were carried the 50-odd miles to Arklow by road.

To revive the legendary Dublin Bay 21 class, the famous Mylne design of 1902-03. Hal Sisk and Fionan de Barra are developing ideas to retain the class's spirit while making the boats more appropriate to today's needs in Dun Laoghaire harbour, with its many other rival sailing attractions. The Dublin Bay 21-foot class's fate represents far more than the loss of a single class; it is bad news for the Bay's yachting heritage at large. Although Dún Laoghaire turned a blind eye to the plight of the oldest intact one-design keelboat fleet in the world for 30 years or more they are now fully restored.

The Dublin Bay 21 Restoration team includes Steve Morris, James Madigan, Hal Sisk, Fionan de Barra, Fintan Ryan and Dan Mill.

Retaining the pure Mylne-designed hull was essential, but the project has new laminated cold-moulded hulls which are being built inverted but will, when finished and upright, be fitted on the original ballast keels, thereby maintaining the boat’s continuity of existence, the presence of the true spirit of the ship.

It will be a gunter-rigged sloop. It was decided a simpler yet clearly vintage rig was needed for the time-constrained sailors of the 21st Century. So, far from bringing the original and almost-mythical gaff cutter rig with jackyard topsail back to life above a traditionally-constructed hull, the project is content to have an attractive gunter-rigged sloop – “American gaff” some would call it.

The first DB 21 to get the treatment was Naneen, originally built in 1905 by Clancy of Dun Laoghaire for T. Cosby Burrowes, a serial boat owner from Cavan.

On Dublin Bay. Dublin Bay Sailing Club granted a racing start for 2020 Tuesday evening racing starting in 2020, but it was deferred due to COVID-19.
Initially, two Dublin Bay 21s will race then three as the boat building project based in Kilrush on the Shannon Estuary completes the six-boat project.
The restored boats will be welcomed back to the Bay in a special DBSC gun salute from committee boat Mac Lir at the start of the season.
In a recollection for Afloat, well known Dun Laoghaire one-design sailor Roger Bannon said: "They were complete bitches of boats to sail, over-canvassed and fundamentally badly balanced. Their construction and design was also seriously flawed which meant that they constantly leaked and required endless expensive maintenance. They suffered from unbelievable lee helm which led to regular swamping's and indeed several sinkings.
