#NAVAL SERVICE NEWBUILDS - Minister for Justice Equality & Defence, Mr. Alan Shatter, T.D., announced on Friday that the building of new Naval Service offshore patrol vessels (OPV) ships is well underway.

The keel laying ceremony of the first of two OPV's took place at Babcock Marine's shipyard in north Devon. Senior representatives of the Naval Service and the Department of Defence attended the ceremony at the UK shipyard which won the €99m contract to build the pair in 2010.

The cost is exclusive of VAT and subject to contract terms and final agreed costs. In addition the cost of providing a weapons system for the ships, similar to the systems on the LE Roisin (P51) and LE Niamh (P52) will be €7.8m, exclusive of VAT.

This pair are of the 'Roisin' class OPV's which were built at the same Devon yard then owned by Appledore Shipbuilders. The newbuilds are of the PV90 design which are a lengthened version of the PV80 class, which were also designed by STX Canada Marine and completed by Appledore in 1999 and 2001.

The PV90 newbuilds will retain the overall configuration of the PV80 but will be increased in length by over 10 metres. They are also to have a slightly deeper draft for improved sea-keeping while patrolling in rougher waters particularly throughout Ireland's extensive naval duties in the Atlantic.

In addition there will be more space at the aft-deck to load on board containers and an increased speed to 23 knots. The will be crew for 44 personnel plus additional quarters for 10 trainee crew.

The payment contract schedule has been arranged over an eight-year timeframe, being 2010 to 2017 and funded from within the annual Defence budget.

The first newbuild is due for delivery in early 2014 followed by the second vessel in 2015. The PV90 class are to replace two of the older Naval Service ships from operational service while maintaining an eight-strong fleet.

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.
