#RESEARCH VESSEL CHARTER - The Geological Survey of Ireland (GSI) have chartered the Cosantoir Bradan from the Central Fisheries Board

The fisheries patrol cutter is to be used in conjunction with the RV Keary for survey work, including bottom survey of all coastal regions around Ireland.

The 15m catamaran inshore research vessel is currently undergoing modifications and refurbishing works at Arklow Marine Services yard.

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.

Two mussel dredger-trawlers made a rare transit of Dalkey Sound, last Friday, writes Jehan Ashmore.

The sound which is located to the south of Dublin Bay is not used by commercial traffic but is frequented by pleasure-craft, local fishing boats from Dun Laoghaire. In addition to occasional traffic by the Irish Naval Service, Marine Institute research vessel RV Celtic Voyager, the GSI's RV Keary and foreign tall-ships.

Leading the pair of mussel dredgers was the Belfast registered Mytilus (B-449) named after the mussel species 'Mytilus edulis' and the Wexford registered Branding (WD-4A).

The vessels were making a southerly direction as they headed across Dublin Bay towards Dalkey Island. Mytilus lowered a mussel cage bucket into the sound which was dragged on two separate occasions over a short distance running parallel between the island and the coast.

The operation was all too brief as the Mytilus then proceeded into Killiney Bay followed closely astern by Branding. Upon entering the neighbouring bay, both vessels conducted dredging activity before continuing south beyond Bray Head.

Mussel grounds are located throughout certain hotspots in the Irish Sea and earlier this month, it is reported that there was a notable increase in mussel dredgers in Bangor, Northern Ireland. The dredgers were the Mytilus and Branding which berthed at the Co. Down harbour after a lengthy period of relative inactivity.

Mytilus was built in The Netherlands by Scheepwerf Van Os Yerseke B.V. and appeared in an episode of the successful BBC TV series 'Coast'. At the time of the broadcast she was registered at Beaumaris, Anglesey and was seen working in the northern approaches of the Menai Straits. The fishery grounds are ideally suited for the growing processes required in farmed mussel production.

Branding was also built by a Dutch shipyard, Kooieman in 1988 and her design is typical of the mussel dredgers based in Wexford. The market for mussels is mainly from the northern European countries of Belgium, France and the Netherlands.

The Co. Wicklow based Maritime Management has been awarded the ISO 9001 and ISO 14001 accreditation by the international accreditation body Germanischer Lloyd. The award to Maritime Management marks the company as a unique provider of ship management services based
in Ireland.
"These awards show our dedication to delivering high quality ship management services, beyond the strict compliance required in this highly regulated industry," said Jan Berg, managing director of Maritime Management.

"Achieving ISO 14001 accreditation, an internationally recognised green standard, shows our respect of the sensitive marine environment and has been well received by our international and Irish clients. It is of particular significance to our clients involved in underwater exploration and scientific research and those involved in the transport of agricultural produce either refrigerated or in bulk."

Maritime Management has an international client base with a diverse range of vessels. Services include technical, operational and crewing for specialist passenger ships, cargoships, refrigerated cargo ships and specialist vessels such as the exploration vessel EV Nautilus.

The vessel is managed on behalf of the famous undersea explorer Dr. Robert Ballard, who is known best for his discovery of the Titanic, PT 109 and the Bismark. Over the last two years Maritime Management has carried out major work to adapt the vessel to suit the requirements of broadcasters National Geographic and CBS.

The work carried outon the vessel has the ground breaking ability to broadcast live HD video from the ocean floor. This enabled scientific teams from the USA and around the world to interact in real time with the underwater operations. To read more about the work of the EV Nautilus and the mapping of underwater volcanoes, life forms,shipwrecks and more click here.

Maritime Management's projects in Ireland have included the design and construction of the Geological Survey of Ireland (GSI) RV Keary, a small yet high-tech survey vessel which was built in South Africa. The 15m asymmetrical catamaran is constructed of aluminium and has a speed of 15 knots. The craft has a Marine Survey Office P5 license for 12 passengers. For further technical details click here.

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
