Survey works for a proposed new submarine communications cable between Ireland and Iceland will be conducted from next week.

The hydrographic survey is due to take place from next Thursday 10 September and will be completed by early November.

Works during the 24/7 cable route survey will involve the stern deployment of a sonar towfish, tethered with steel cable at varying water depths, to collect geophysical/bathymetric mapping data for the proposed undersea telecommunications cable along a 540km route.

The survey will be conducted from the RV Ridley Thomas (Callsign V7JK2), which will be restricted in its ability to manoeuvre.

All other vessels, including fishing vessels, are requested to maintain distance of at least one nautical mile at all times.

Co-ordinates of the search area as well as relevant contact details are included in Marine Notice No 37 of 2020, which is available to download below.

Hydrographic and geophysical surveys will be undertaken in the Irish Sea off the Wicklow coast between June and September 2019 to provide bathymetric and subsurface information to facilitate the development of the Arklow Bank Wind Park.

The survey dates are weather dependent but are anticipated to start in June and be completed by the end of September.

The location of the surveys will be off the Wicklow coastline. They will be completed using two vessels working in parallel across the site. The vessels involved are the AMS Panther (Callsign: 2EHC2), which is a 17m windfarm support catamaran, and the AMS Retriever (Callsign: MEHI8) which is a versatile multi-purpose shallow draft tug.

Both vessels will be engaged in survey operations and will be restricted in their ability to manoeuvre. The vessels will be towing survey equipment up to 100 metres astern. Vessels are requested to leave a wide berth. The vessels will be operating 24 hours per day during survey works.

Details of the survey area and relevant co-ordinates are included in Marine Notice No 11 of 2019, a PDF of which is available to read or download HERE.

#MarineNotice - INFOMAR will undertake a hydrographic and geophysical survey in Donegal Bay next weekend 24-25 May.

The RV Celtic Voyager (Call sign EIQN) is expected to carry out the survey operations, which follow up on a previous survey completed last month.

Though the vessel will not be towing any instruments during this survey, she will have limited limited manoeuvrability due to survey line constraints.

The vessel will display appropriate lights and markers, and will be listening on VHF Channel 16 throughout the project.

Details of the survey area are included in Marine Notice No 31 of 2014, a PDF of which is available to read or download HERE.

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).
