On a rare occasion both the Marine Institute's research vessels docked in both Dublin Bay ports today, normally these vessels operate mostly off the western seaboard and using their home-port of Galway Harbour, writes Jehan Ashmore.
The 65m RV Celtic Explorer (2002 /2,425grt) made an early morning call to Dublin Port's Ocean Pier. Her smaller fleet-mate RV Celtic Voyager (1996/340grt) made a midday arrival to Dun Laoghaire Harbour's East Pier. She moored at the same berth last month, as previously reported on Afloat.ie The larger vessel has a greater range capability while the smaller vessel covers more inshore-work throughout the Irish coastline.

According to the vessels survey schedules, RV Celtic Explorer had today completed fisheries demersal surveys which started in Galway on 23 September. The near fortnight-long survey was conducted in the ICES area VI, under the direction of chief scientist, Dave Stokes.

On Friday she embarks on a herring acoustic survey which is to take place in the Celtic Sea and the south-west. This survey will be under chief scientist Ciaran O'Donnell and is to de-mobilise in Cork on 27 October. To read more about her 2011 survey programme click HERE.

Across Dublin Bay in neighbouring Dun Laoghaire, the 31m RV Celtic Voyager is currently nearing the end of a month-long hydrography survey of the Celtic Sea. The survey had started in Howth Harbour on 17 September under chief scientist Kevin Sheehan. For the time-being she remains moored in Dun Laoghaire prior to resuming survey work which will continue until the vessel de-mobilises in Rosslare in mid-October. To find out more about her remaining surveys for this year click HERE.

On the surveys outlined they are conducted on behalf of Marine Institute scientists, though the vessels are also allocated ship-time for use of third parties. These include government departments and agencies, universities, research institutes and industry.

The Marine Institute's two research vessels, RV Celtic Explorer and RV Celtic Voyager are to lead Europe with an all-time record of 627 days spent at sea of between both ships, well above the average for equivalent European research vessels.
In 2011, the RV Celtic Explorer is scheduled for 17 surveys in Irish waters resulting in 344 days at sea and the RV Celtic Voyager with 29 surveys resulting in 283 days at sea. In comparison, in 2010 the RV Celtic Explorer spent 308 days at sea with 18 surveys and as well as undergoing a refit. The Celtic Voyager took 280 sea-going days resulting in 32 surveys.

These figures compare favourably with our European counterparts, reflecting a high level of activity on national and international research and monitoring programmes.

Work duties in 2011 for the Galway based vessels will range from fisheries surveys to underwater mapping and from climate studies to deepwater surveys with the remotely operated submersible ROV Holland 1. The work schedule will facilitate training missions and to carry out essential maintenance work on Ireland's network of data buoys that, in parallel to their research function, supply the vital information on which weather and shipping forecasts are based.

The increased activity of the research vessels reflects the growing imperative to understand and sustainably manage the economic potential of our offshore marine territories, an area over ten times that of Ireland itself.

A major role of the ships' workload will be commercial fish stock assessments. Together they are to devote 141 days on stock surveys in support of the sustainable management of Ireland's fisheries.

The RV Celtic Voyager will conduct underwater television surveys of valuable prawn stocks off the Aran Islands, the Irish and Celtic Seas, working on blue whiting, a survey of herring stocks in the north-west. In addition a comprehensive 54-day annual Irish Groundfish Survey which will take place in stages all around the Irish coast from September to December.

The survey will be the largest undertaken by an Irish research vessel and is essential to providing the scientific data used to inform the annual quota negotiations required in Brussels each year.

For the 2011 schedule for both vessels is available to view by clicking HERE and the Maritime Institute website click this link.

At 65.5m RV Celtic Explorer (2,425grt) accommodates 35 personnel and up to 21 scientists and 31.4m RV Celtic Voyager (340grt) with up to 8 scientists and a maximum endurance of 14-day days.

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.
