#MARINE WARNING - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises mariners of cable laying operations in the Irish Sea from next week onwards.

The cable laying operations between Wales and Portmarnock Beach in north Co Dublin will commence on Thursday 25 October for approximately 14 days, subject to weather conditions. The works will be undertaken from the C/S Resolute (Call sign V7FF3) supported by the M/V Coastal Discovery (Call sign PBUZ).

Both vessels will display appropriate shapes and lights during the operations, and will keep a listening watch on VHF Channel 16 at all times.

Mariners are particularly advised to note that small craft will also be supporting the main operations vessels in the immediate area of Portmarnock Beach. These craft will have VHF communications, and their movements will be co-ordinated by the main vessels.

In addition, divers will be operating between Portmarnock Beach and the cable laying vessel within the approved corridor for these work and to a maximum distance of 6.5km from the shore.

All vessels, particularly those engaged in fishing, are requested to give all vessels involved in these operations a wide berth.

Full details of co-ordinates are included in Marine Notice No 59 of 2012, a PDF of which is available to read or download HERE.

Published in Marine Warning

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.
