Amongst the festival tallships lining Waterford quays, the RV Keary, a marine research survey vessel that mapped the estuary in advance of the tall ships arrival, will too be open to the public, writes Jehan Ashmore.
Work to map the navigational channel of Waterford Harbour's estuary was completed last month by the catamaran hulled craft that belongs to the Geological Survey of Ireland (GSI). Her smaller fleetmate the 7.5m RIB RV Geo carried-out work in the shallower areas along the river banks. For images of the seabed survey click HERE. The survey which had started in April was a joint research programme between (GSI) and the Marine Institute (MI).

This was the RV Keary's first INFOMAR survey leg of 2011 and it was also the first time that both vessels have worked in tandem. The mapping of the estuary was from an area just west of the city's Rice Bridge to the open sea at the mouth of Waterford Harbour.

The estuary was mapped before in 2007 using the Marine Institutes larger vessel the RV Celtic Voyager, which covered the harbour approaches from the 10m contour to greater depth offshore. Both RV Keary and RV Geo overlapped their coverage with this previous data, producing a comprehensive and seamless seabed map of the area.

RV Keary is constructed of marine grade aluminium and was custom built in 2008 for the (GSI) by Veecraft Marine of Capetown, South Africa.
The 15m craft with a draft of just 2m is equipped with an extensive range of highly sophisticated technology. She has an open working area at the aft-deck to conduct operations and is licensed to carry up to 12 personnel. For further vessel characteristics click HERE.

The 34-tonne craft made her 7,000 mile delivery voyage from the African continent to Europe. She was firstly transported on the deck of a cargoship to Rotterdam. After unloading at the Dutch port the 22-knot capable craft set off with several calls along the UK south coast to include loading bunkers before finally reaching Dun Laoghaire, from where she entered service in April 2009.

The 2024 Vendée Globe Race

A record-sized fleet of 44 skippers are aiming for the tenth edition of the Vendée Globe: the 24,296 nautical miles solo non-stop round-the-world race from Les Sables d’Olonne in France, on Sunday, November 10 2024 and will be expected back in mid-January 2025.

Vendée Globe Race FAQs

Six women (Alexia Barrier, Clarisse Cremer, Isabelle Joschke, Sam Davies, Miranda Merron, Pip Hare).

Nine nations (France, Germany, Japan, Finland, Spain, Switzerland, Australia, and Great Britain)

After much speculation following Galway man Enda O’Coineen’s 2016 race debut for Ireland, there were as many as four campaigns proposed at one point, but unfortunately, none have reached the start line.

The Vendée Globe is a sailing race round the world, solo, non-stop and without assistance. It takes place every four years and it is regarded as the Everest of sailing. The event followed in the wake of the Golden Globe which had initiated the first circumnavigation of this type via the three capes (Good Hope, Leeuwin and Horn) in 1968.

The record to beat is Armel Le Cléac’h 74 days 3h 35 minutes 46s set in 2017. Some pundits are saying the boats could beat a sub-60 day time.

The number of theoretical miles to cover is 24,296 miles (45,000 km).

The IMOCA 60 ("Open 60"), is a development class monohull sailing yacht run by the International Monohull Open Class Association (IMOCA). The class pinnacle events are single or two-person ocean races, such as the Route du Rhum and the Vendée Globe.

Zero past winners are competing but two podiums 2017: Alex Thomson second, Jérémie Beyou third. It is also the fifth participation for Jean Le Cam and Alex Thomson, fourth for Arnaud Boissières and Jérémie Beyou.

The youngest on this ninth edition of the race is Alan Roura, 27 years old.

The oldest on this ninth edition is Jean Le Cam, 61 years old.

Over half the fleet are debutantes, totalling 18 first-timers.

The start procedure begins 8 minutes before the gun fires with the warning signal. At 4 minutes before, for the preparatory signal, the skipper must be alone on board, follow the countdown and take the line at the start signal at 13:02hrs local time. If an IMOCA crosses the line too early, it incurs a penalty of 5 hours which they will have to complete on the course before the latitude 38 ° 40 N (just north of Lisbon latitude). For safety reasons, there is no opportunity to turn back and recross the line. A competitor who has not crossed the starting line 60 minutes after the signal will be considered as not starting. They will have to wait until a time indicated by the race committee to start again. No departure will be given after November 18, 2020, at 1:02 p.m when the line closes.

The first boat could be home in sixty days. Expect the leaders from January 7th 2021 but to beat the 2017 race record they need to finish by January 19 2021.

Today, building a brand new IMOCA generally costs between 4.2 and €4.7million, without the sails but second-hand boats that are in short supply can be got for around €1m.
