#Lighthouses - A workboat operating from Dun Laoghaire Harbour which was used to assist the Commissioners of Irish Lights has completed duties offshore at the Kish Lighthouse, writes Jehan Ashmore.

The Westport registered workboat, James, Afloat spotted since the summer has in recent weeks returned to Dun Laoghaire to complete the refurbishment of the Kish Bank Lighthouse, which through a public tender procurement application was contracted to Cunningham Civil & Marine.  

In order to carry out refurbishment of the lighthouse exterior which involved dismantling, fabricating and erecting a new helipad, Cunningham Civil engaged the services of O'Malley Marine Plant Ltd, by hiring from the newly formed company their landing craft workboat James. The craft during the project was based out of Dun Laoghaire Harbour at the Irish Lights depot. 

Afloat can also reveal the works saw the removal of the disused crane equipment from the 31m high structure. This is where lighthouse keepers worked and were accommodated until automation took over in 1992. 

Cunningham Civil as consultants engaged in the project, followed a major structural review of the Kish Lighthouse in 2015 (50th anniversary, see Afloat coverage). The review found the tower to be structurally sound but made a number of recommendations among them metal fixtures such as the helipad and the crane. 

The Kish Lighthouse became operational in 1965 and currently has a range of 22 nautical miles.

On completion of the installation of the tower this replaced a lightship stationed on the Kish Bank. Previous lightships can be traced back to 1811 when the first light was exhibited to provide a navigation mark to shipping using the Port of Dublin and to passing traffic.

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.
