#DryDocking - ILV Granuaile (2000/2,625grt) departed Cork Harbour and is bound for Rosslare Harbour this evening having undergone dry-docking, writes Jehan Ashmore.

Among the work carried out on the Commissioners of Irish Lights tender at Cork Dockyard were some service work done on thrusters and re-chroming of crane rams.

The Dutch Damen Group which built the vessel at their Romanian yard in Galati, had also undergone in Cork Dockyard last year a major '15 Special Survey & Dry-Docking'. The Rushbrooke yard fought off stiff competition for the EU tender as part of a €650,000 project to enable continued operation to Lloyds +100A1 Classification.

ILV Granuaile yesterday morning departed a river-berth for sea-trials. This involved the 79m long lighthouse tender pass Cobh to where a pair of UK registered factory trawlers berthed following detention off the Blaskets by the Naval Service.

She then headed beyond Roches Point Lighthouse, marking the entrance to Cork Harbour from where a circuit was made at sea before returning to the dockyard. 

The trawlers Wiron 5 and Wiron 6 are 55m in length and have a Dutch crew of 14 each. They were detained for alleged fishery infringements by the OPV L.E. Samuel Beckett (P61) which escorted the vessels to Cobh and then she headed upriver to berth in Cork City quays.

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.
