#FrenchMineHunter - French Navy "tripartite" minehunter Andromède (M 643) is to be the third visitor by the nation to call to Dublin Port this year, writes Jehan Ashmore.

Unlike the Type A69 corvette FS Lieutenant de Vaisseau Lavallée (F 790) which berthed in the centre of Dublin Port last week, the minehunter is to dock closer to the city centre on the Liffey.

The design origins of the 51m minehunter stems from a commitment to construct a minehunter warfare vessel to meet the needs, share technologies and also reduce costs of building units for the French, Belgium and Dutch Navies.

Andromède has served globally among international operations in the Persian Gulf in 1991 having entered into commissioned service in 1984.

The 615 tonnes displacement minehunster was completed by la Direction des Constructions Navales (DCN) in Lorient, Brittany.

#MineHunter – Following last week's notable visit of Dutch submarine HNMLS Dolfijn (S808) to Cork City Quays, the Belgium Navy's minehunter BNS Primula (M924) is currently at anchorage in the lower harbour, writes Jehan Ashmore.

Accompanying the BNS Primula is the auxiliary vessel BNS Stern (A963) which is also anchored in Cobh Roads.

BNS Primula is a Tripartite-class minehunter and forms part of the Belgian Naval Component and she has a 595 tonnes displacement. She was launched in 1990 at the Mercantile-Belyard shipyard in Rupelmonde.

The Tripartite class vessel represents the final of ten of the series commissioned for the Belgian Navy. Neighbouring nations Netherlands and France completed the Tripartite partnership in the design and development of the class.

Tripartite class vessels from these nations have been regular visitors to Irish ports unlike the rare sight of a submarine in an Irish port as demonstrated by HNLMS Dolfijn.

The submarine's visit was made more the unusual in that she could be clearly seen moored at the Cork city-centre berth rather than a downriver location which compared to some other Irish ports can be more discreet from public view.

The 'Walrus' class submarine had made the upriver transit of Cork Harbour to the city centre (click previous report and scroll down for footage) and is seen passing near Monkstown.

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.
