The Department of Transport has been advised of a geophysical marine route survey operation taking place in the Northeast Atlantic Ocean off Galway and Mayo from next week.

The survey activity will take place within the Irish TS, Irish CZ and Irish EEZ and is scheduled to begin today, Monday 7 June for completion some five months later in early November, weather permitting.

The survey will be conducted by the RV Ridley Thomas (callsign V7JK2) which will undertake 24/7 cable route operations.

Survey operations will include the stern deployment of a sonar towfish tethered with steel cable at varying water depths, to collect geophysical/bathymetric mapping data for a proposed undersea telecommunications cable.

The vessel will be monitoring VHF channels 16 and 13, and will display appropriate lights and signals. All vessels operating within the survey areas are requested to keep their distance, maintaining a safety zone around the survey vessel and pass at minimum speed to reduce vessel wash.

Full details of the survey, including relevant coordinates, are included in Marine Notice No 35 of 2021 which can be downloaded below.

Green Rebel Marine in Crosshaven intends to conduct geophysical survey operations off the South Coast between Cork and Waterford cities over an extended period of time, up to a year from this Thursday 3 June.

The survey 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.

The geophysical survey will use a multibeam echosounder and sub-bottom profilers, which will be hull-mounted, as well as side-scan sonars and magnetometers that will be towed using dedicated winches at cable lengths dictated by the water depth (typically four times the water depth while acquiring data).

Full details of coordinates of the survey areas are included in Marine Notice No 33 of 2021, a PDF of which can be downloaded below.

RORC Fastnet Race

This race is both a blue riband international yachting fixture and a biennial offshore pilgrimage that attracts crews from all walks of life:- from aspiring sailors to professional crews; all ages and all professions. Some are racing for charity, others for a personal challenge.

For the world's top professional sailors, it is a 'must-do' race. For some, it will be their first-ever race, and for others, something they have competed in for over 50 years! The race attracts the most diverse fleet of yachts, from beautiful classic yachts to some of the fastest racing machines on the planet – and everything in between.

The testing course passes eight famous landmarks along the route: The Needles, Portland Bill, Start Point, the Lizard, Land’s End, the Fastnet Rock, Bishop’s Rock off the Scillies and Plymouth breakwater (now Cherbourg for 2021 and 2023). After the start in Cowes, the fleet heads westward down The Solent, before exiting into the English Channel at Hurst Castle. The finish for 2021 is in Cherbourg via the Fastnet Rock, off the southern tip of Ireland.

  • The leg across the Celtic Sea to (and from) the Fastnet Rock is known to be unpredictable and challenging. The competitors are exposed to fast-moving Atlantic weather systems and the fleet often encounter tough conditions
  • Flawless decision-making, determination and total commitment are the essential requirements. Crews have to manage and anticipate the changing tidal and meteorological conditions imposed by the complex course
  • The symbol of the race is the Fastnet Rock, located off the southern coast of Ireland. Also known as the Teardrop of Ireland, the Rock marks an evocative turning point in the challenging race
  • Once sailors reach the Fastnet Rock, they are well over halfway to the finish in Cherbourg.

Fastnet Race - FAQs

The 49th edition of the biennial Rolex Fastnet Race will start from the Royal Yacht Squadron line in Cowes, UK on Sunday 8th August 2021.

The next two editions of the race in 2021 and 2023 will finish in Cherbourg-en-Cotentin at the head of the Normandy peninsula, France

Over 300. A record fleet is once again anticipated for the world's largest offshore yacht race.

The international fleet attracts both enthusiastic amateur, the seasoned offshore racer, as well as out-and-out professionals from all corners of the world.

Boats of all shapes, sizes and age take part in this historic race, from 9m-34m (30-110ft) – and everything in between.

The Fastnet Race multihull course record is: 1 day 4 hours 2 minutes and 26 seconds (2019, Ultim Maxi Edmond de Rothschild, Franck Cammas / Charles Caudrelier)

The Fastnet Race monohull course record is: 1 day, 18 hours, 39 minutes (2011, Volvo 70, Abu Dhabi Ocean Racing).

David and Peter Askew's American VO70 Wizard won the 2019 Rolex Fastnet Race, claiming the Fastnet Challenge Cup for 1st in IRC Overall.

Rolex SA has been a longstanding sponsor of the race since 2001.

The first race was in 1925 with 7 boats. The Royal Ocean Racing Club was set up as a result.

The winner of the first Fastnet Race was the former pilot cutter Jolie Brise, a boat that is still sailing today.

Cork sailor Henry P F Donegan (1870-1940), who gave his total support for the Fastnet Race from its inception in 1925 and competed in the inaugural race in his 43ft cutter Gull from Cork.

Ireland has won the Fastnet Race twice. In 1987 the Dubois 40 Irish Independent won the Fastnet Race overall for the first time and then in 2007 – all of twenty years after Irish Independent’s win – Ireland secured the overall win again this time thanks to Ger O’Rourke’s Cookson 50 Chieftain from the Royal Western Yacht Club of Ireland in Kilrush.
