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.

SB20 (formerly Laser SB3) information

Designed by Tony Castro, the SB20 is a British-built strict one-design 6.15m keelboat conceived as a wide appeal, affordable, competitive sportsboat for teams of three or four sailors. It is also, arguably, the most successful sportsboat in the world with 800 owners competing regularly in a programme of exciting local, national and international events.

Originally known as the Laser SB3, the SB20 continues to deliver on its pioneering promise: a boat that is fun, fast and easy to sail by anyone of any age; the best value-for-money sportsboat in the market.

The Laser SB3 was designed by Castro and launched in 2002. In 2007 the Laser SB3 was awarded ISAF Recognised Status and the first World Championships were held in Ireland in 2008. In 2012, Tony Castro appointed a new builder, Sportsboat World. At this time, the Laser SB3 was renamed the SB20 and building was returned to the UK from Malaysia. The ethos of the class continues.

The boat is a strict one-design class, economic to buy and campaign, easy to sail with a simple deck layout and electric downwind performance delivered by the generous sail plan. The boat has a lifting keel, can easily be launched from a slipway and towed behind a family car.
