Fuinneamh Sceirde Teoranta (FST) will be undertaking both a geotechnical survey and geophysical survey for the Sceirde Rocks Windfarm Project in the Western Coastal Area (Connemara/Outer Galway Bay) and Atlantic Ocean, between Monday 15 April and Monday 10 June, subject to weather and operational constraints.

These surveys follow last September’s geophysical survey and will be undertaken by the multi-purpose offshore vessel Dina Polaris (callsign CQOF), which is fitted with a geotechnical drilling rig, and the research vessel Lady Kathleen (callsign EIXT2). Both vessels will operate up to 24 hours per day and will be displaying the appropriate lights and shapes.

During operations, the vessels will be restricted in their ability to manoeuvre. Therefore, passing vessels are requested to leave a wide berth during the deployment operations. Radio transmissions will be conducted with other seafarers to notify them of the operations. The vessels will be monitoring VHF Channel 16 at all times for safety purposes.

The equipment for each survey will be deployed within the bounds of the survey areas detailed in Marine Notice No 17 of 2024, attached below.

The Department of Transport has been advised by Fuinneamh Sceirde Teoranta (FST) that benthic and geotechnical survey vessels will be deployed at the site of the proposed Sceirde Rocks Windfarm in north Galway Bay off southwestern Connemara.

The deployment will take place from this Saturday 29 July — as with the metocean survey previously reported on Afloat.ie — to the end of September, subject to weather and operational constraints.

The benthic survey will take place using the vessel Ocean Navigator (callsign EI018) which will operate in daylight hours. The geotechnical survey will take place using the vessels Geoquip Seehorn (callsign 5BSW) and Glomar Vantage (callsign HO3057) which will operate on a 24-hour basis.

Coordinates and a map of the deployment area as well as contact details can be found in Marine Notice No 47 of 2023, attached below.

The Department of Transport has been advised that a geophysical and geotechnical surveys is being undertaken by Green Rebel Marine in the Irish Sea to assess cable burial on behalf of MDM.

The survey work was anticipated to start on Monday 19 June and will be completed by the end of September, subject to weather and operational constraints.

Surveys will be conducted by two vessels: the semi-SWATH catamaran Roman Rebel (callsign 2ICA5) which will conduct 24-hr operations, and the Lady Kathleen (callsign EIXT2), a catamaran which will conduct 12-hr operations. Both vessels will display appropriate lights and signals.

As the survey vessels will be restricted in their ability to manoeuvre when surveying, due to the deployment of the towed survey equipment from the vessel for the duration of the survey activities, other vessels are kindly requested to keep a wide berth.

Mariners are advised to keep continuous watch on VHF Channel 16 when navigating the area.

Coordinates and a map of the survey areas as well as contact details can be found in Marine Notice No 40 of 2023, attached below.

EGS International Ltd is undertaking a geophysical survey campaign for a proposed offshore wind farm and associated export cable corridor centred around Sceirde Rocks, off the west coast of Ireland near Galway.

The survey was set to commence last week on Friday 10 June and will continue throughout June, July and possibly into August, weather permitting.

The operations will take place in two locations: the Wider Array Site off the coast of Connemara and the Export Cable Corridor (ECC) to the west of the Aran Islands and towards the coast of Co Clare.

The work is being conducted by the EGS Ventus (callsign V7119), which will display the appropriate day shapes/signals and lights as required by the COLREGS and maintain a continuous listening watch on VHF Channel 16 and Digital Selective Calling (DSC).

The vessel will be towing survey equipment astern at 4 knots, which will restrict its ability to manoeuvre. All other vessels operating within this area are requested to keep their distance and pass at minimum speed to reduce vessel wash.

Contact details, coordinates and maps of the survey areas are included in Marine Notice No 36 of 2022, attached below.

Elsewhere, Fugro is engaged in a geotechnical site survey campaign for wind farms in the South Irish Sea (off the Wexford coast) and North Celtic Sea (off the Waterford coast).

Operations were expected to begin on Sunday 12 June and will continue till approximately Tuesday 28 June, weather allowing.

The work is being conducted by the Normand Mermaid (callsign LAXH7) on a 24-hour basis. The vessel will display appropriate lights and markers.

For further details see Marine Notice No 35 of 2022, also attached below.

Howth 17 information

The oldest one-design keelboat racing class in the world is still competing today to its original 1897 design exclusively at Howth Yacht club.

Howth 17 FAQs

The Howth 17 is a type of keelboat. It is a 3-man single-design keelboat designed to race in the waters off Howth and Dublin Bay.

The Howth Seventeen is just 22ft 6ins in hull length.

The Howth 17 class is raced and maintained by the Association members preserving the unique heritage of the boats. Association Members maintain the vibrancy of the Class by racing and cruising together as a class and also encourage new participants to the Class in order to maintain succession. This philosophy is taken account of and explained when the boats are sold.

The boat is the oldest one-design keelboat racing class in the world and it is still racing today to its original design exclusively at Howth Yacht club. It has important historical and heritage value keep alive by a vibrant class of members who race and cruise the boats.

Although 21 boats are in existence, a full fleet rarely sails buy turnouts for the annual championships are regularly in the high teens.

The plans of the Howth 17 were originally drawn by Walter Herbert Boyd in 1897 for Howth Sailing Club. The boat was launched in Ireland in 1898.

They were originally built by John Hilditch at Carrickfergus, County Down. Initially, five boats were constructed by him and sailed the 90-mile passage to Howth in the spring of 1898. The latest Number 21 was built in France in 2017.

The Howth 17s were designed to combat local conditions in Howth that many of the keel-less boats of that era such as the 'Half-Rater' would have found difficult.

The original fleet of five, Rita, Leila, Silver Moon, Aura and Hera, was increased in 1900 with the addition of Pauline, Zaida and Anita. By 1913 the class had increased to fourteen boats. The extra nine were commissioned by Dublin Bay Sailing Club for racing from Kingstown (Dún Laoghaire) - Echo, Sylvia, Mimosa, Deilginis, Rosemary, Gladys, Bobolink, Eileen and Nautilus. Gradually the boats found their way to Howth from various places, including the Solent and by the latter part of the 20th century they were all based there. The class, however, was reduced to 15 due to mishaps and storm damage for a few short years but in May 1988 Isobel and Erica were launched at Howth Yacht Club, the boats having been built in a shed at Howth Castle - the first of the class actually built in Howth.

The basic wooden Howth 17 specification was for a stem and keel of oak and elm, deadwood and frames of oak, planking of yellow pine above the waterline and red pine below, a shelf of pitch pine and a topstrake of teak, larch deck-beams and yellow pine planking and Baltic spruce spars with a keel of lead. Other than the inclusion of teak, the boats were designed to be built of materials which at that time were readily available. However today yellow pine and pitch pine are scarce, their properties of endurance and longevity much appreciated and very much in evidence on the original five boats.

 

It is always a busy 60-race season of regular midweek evening and Saturday afternoon contests plus regattas and the Howth Autumn League.

In 2017, a new Howth 17 Orla, No 21, was built for Ian Malcolm. The construction of Orla began in September 2016 at Skol ar Mor, the boat-building school run by American Mike Newmeyer and his dedicated team of instructor-craftsmen at Mesquer in southern Brittany. In 2018, Storm Emma wrought extensive destruction through the seven Howth Seventeens stored in their much-damaged shed on Howth’s East Pier at the beginning of March 2018, it was feared that several of the boats – which since 1898 have been the very heart of Howth sailing – would be written off. But in the end only one – David O’Connell’s Anita built in 1900 by James Clancy of Dun Laoghaire – was assessed as needing a complete re-build. Anita was rebuilt by Paul Robert and his team at Les Ateliers de l’Enfer in Douarnenez in Brittany in 2019 and Brought home to Howth.

The Howth 17 has a gaff rig.

The total sail area is 305 sq ft (28.3 m2).
