The latest Marine Notice from the Department of Transport gives advance notice of the discontinuation of the Differential Global Positioning System (DGPS) service around the coast of the island of Ireland from 31 March 2022.

DGPS has been provided as an augmentation service of the GPS signal by the General Lighthouse Authorities in Ireland and the UK since 1997.

The Commissioners of Irish Lights, in consultation with the Department of Transport, have resolved that the DGPS service has now become redundant and has decided to discontinue the service in waters around the coast of the island of Ireland after 31 March 2022.

Further information and guidance for maritime users is available on the Irish Lights website. This explains the background, consultation with the wider DGPS user group and guidance for maintaining the safety of navigation after the DGPS service ceases next spring.

#Lifejackets - The Sunday Independent writes on Donegal firm Mullion Survival Technology's new innovative lifejackets that come with the latest tech to ensure help comes quickly.

The compact design sits like a collar around the user, with plenty of room for movement, but most important is the built-in GPS beacon that pinpoints the location of the user to rescuers, and a bright light that activates automatically once they hit the water.

What's more, each Mullion lifejacket is registered to a particular user, so that emergency services can know exactly who they're searching for when the alarm is raised.

Mullion's devices have already been credited with saving the life of a fisherman off Co Down, as previously reported on Afloat.ie, and as of this year will be the standard personal flotation device (PFD) for the Irish fishing fleet.

#Navigation - Marine navigation systems in yachting and shipping are 'primitive' compared to the standard in air travel, according to an electronics expert.

As Yachting Monthly reports, Martin Bransby of the UK's General Lighthouse Authorities said that "demands on marine navigation are only getting tighter, yet electronic systems at sea a primitive compared to those used in air travel. This needs to change."

Bransby made his comments following a trial to tackle the problem of rogue GPS jammers in the North Sea by the lighthouse authorities at Trinity House.

The new PNT (positioning, navigation and timing) method uses new technology to transmit critical data in the even of the loss or failure of GPS, which is vulnerable to interference from a variety of sources, both environmental and deliberate.

"The more dependent we become on electronic systems, the more resilient they must be," said Bransby. "Otherwise, we face a scenario where technology is actually reducing safety rather than enhancing it."

These new trials come after news that the Irish Coast Guard is collaborating on a new system of marine monitoring that will help detect drifting or rogue vessels in international waters before they become a problem for individual states - such as the 'ghost ship' MV Lyubov Orlova which as of last week was still adrift heading eastwards somewhere in the North Atlantic.

The Irish GPS Speedsailing record fell again last Friday in Dungarvan when Oisin Van Gelderen broke all previous speeds, becoming the fastest sailor ever to sail on Irish waters.

The speed is ratified by the WGPSSRC (World GPS Speedsailing Records Council):  
http://www.gps-speedsurfing.com/default.aspx?mnu=records, who issue GPS records based on the best 10 second run of 45.02 knots, and a distance travelled of around 270 metres in this time.

The 5 x 10second run average, currently puts him in fourth overall on the 2011 GPS speed ranking list and 23rd overall in the all time rankings.
Peak speed for the day was 46.32 knots (84 kmph), and 500m speed was 43.96knots.

Even though Van Gelderen broke the late John Kenny's 500m speed, he retains that title for now, as the WSSRC (World Speed sailing Records Council) issue National records for that distance, and do not yet recognize GPS.

The rise in popularity in GPS speedsailing has made the competition a worldwide phenomenon, as people from different countries compete year round to push their personal and international speeds. Over 4000 members subscribe to the gps-speedsurfing.com website.

Boating electronics provider Raymarine was saved from collapse over the weekend with a last-minute buyout.

Negotiations with a 'third party', which turned out to be the eventual purchaser, broke down momentarily, with GPS company Garmin making a last-ditch bid to buy the company. The bid would have been subject to receiving the green light by competition authorities.

Raymarine plc was forced to go into administration when its banking consortium withdrew finance on May 13, casting the future of the company into some turmoil.

As a result, Raymarine plc was put into administration on Friday, with all the working business elements of Raymarine Holdings then immediately sold out of adminstration to the original third party.

The eventual purchaser was Flir Systems, a US-based thermal imaging company, which bought Raymarine at a valuation of £124 million, making a 20-pence-per-share return to shareholders. The purchase price includes Raymarine's debt, which has been put at close to £100million, but the per-share return may diminish further once creditors claims come in.

Although Garmin's per-share bid was higher (£0.35 per share), the immediacy of the Flir bid made it more palatable to the administrators.

The transaction ensures business as usual for Raymarine customers and suppliers.

Raymarine is one of the world's leading radar, GPS and marine instrumentation brands. Flir are a major manufacturer of thermal imaging cameras

All documents relating to the sale can be viewed on Raymarine's investor relations page.

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.
