#CorkHarbour – The increasing strategic importance of Cork Harbour as a base for the oil and gas energy sector in the search for natural resources particularly off our southern shores, is evident with this recent view taken by our colleagues of the platform supply vessel (PSV) Bourbon Clear passing Cobh, writes Jehan Ashmore.

Not only is Bourbon Clear painted with a distinctive green hull but also features an unconventional bow which is of the X-BOW design, a unique and environmentally-friendly hull line design that is patented by her Norwegian developers Ulstein.

The odd looking X-Bow has an inverted bow design which was first introduced in 2005 with the Bourbon Orca, her introduction caused quite a splash in the offshore maritime world and beyond.

Since then, more 60 vessels of various designs have been completed with the specialist bow form which claims to improve handling in rough seas and in reduced levels of fuel consumption.

The 4,000 tonnes newbuild has further Nordic connections as the owners are Bourbon Offshore Norway. The company have a fleet of vessels that utilizise in the very latest design and technology so to provide supplies to oil and oil-related companies all over the world.

Currently Bourbon have newbuilds under construction and they are of the Ulstein PX105 PSV design in which the 80m Bourbon Clear belongs to this series having been launched last year from a Chinese shipyard.

Bourbon Clear has called previously to Cobh Cruise Terminal and in the background of the (TOP) photo, is yet another Norwegian flagged vessel, Hurtigruten's Fram, the polar expedition cruiseship which visited Dublin Port yesterday.

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.
