#NavalService - The Irish Naval Service flagship LÉ Eithne has recently been accredited as the first in the fleet to achieve "paperless navigation” writes Jehan Ashmore

The 1984 custom-built P30 class Helicopter Patrol Vessel (HPV), Afloat adds notably the last Irish built vessel for the Naval Service and of any ship in the Republic, now has Warship Electronic Chart Display and Information System (WECDIS).

The milestone took place this day last week, where the electronic systems according to the INS will greatly enhance navigation safety, situation awareness & tactical planning capabilities.

L.É Eithne is in the same company of the ageing P40's Coastal Patrol Vessel (CPV) pair, L.É. Orla and L.É. Ciara which also date to 1984, though they were originally commissioned for the UK Royal Navy. 

The remaining patrol vessels of the fleet are all Offshore Patrol Vessels (OPV), beginning with the elder pair of P50 Róisín class L.É. Róisín and L.É Niamh, the latter completed in 2000. The reference to '80' refers to the length overall (LOA) of each of the sisters built by Appledore Shipbuilders, north Devon.

They are to recieve mid-life extension survey refits involving a Scottish marine consultancy firm.

A further trio, known as enhanced Róisín class followed suit, again from the same UK shipbuilder site but under management of Babcock Marine. They are the P60 OPV90's L.É. Samuel Beckett, James Joyce and William Butler Yeats.

The latest newbuild, again a OPV90 class, L.É. George Bernard Shaw was completed this year, though it would appear that the 2,250 tonnes vessel is the final to be built at the yard, following announcement of closure.

L.É. George Bernard Shaw is currently not part of the 8-strong fleet. As reported earlier this year, the €67m OPV newbuild is according to the IDF to be formally named and officially commissioned into the Naval Service this year.

Plans are afoot to replace LÉ Eithne with a new Multi Role Vessel MRV (a first for the INS), following the Budget, where total Defence spending across the three branch forces (air corps, army and navy) is to increase to €946m next year.

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.
