The Finnish Navy minelayer FNS Hämeenmaa is to dock in the Port of Cork at the city's central North Custom House Quay tomorrow morning, writes Jehan Ashmore.

FNS Hämeenmaa entered service in 1992 and measures 1,450 tonnes, she is the namesake class of two minelayers, the second FNS Uusimaa was also built by Finnyards in the same year.

At nearly 78m long the steel hulled vessels which have an alloy superstructure are designed to operate throughout the year in the demanding Baltic Sea conditions and the in the archipelago's.

They have an ice operating classification of ICE-1A and for military purposes they became one of first Finnish Navy vessels to incorporate stealth technology features. The pair are primarily tasked for minelaying duties but they also provide roles acting as an escort, transport and depot ships.

Armament comprises of 1 × Bofors 57 mm dual-purpose gun, 1 × eight-cell ItO 04 surface-to-air missile launcher, 2 × anti-submarine rocket launchers, 2 × depth charge rails and 100-150 sea mines (four mine laying rails).

Based in Pansio, the 20 knot vessels each have a crew complement of 60 personal. In total the Finnish Navy has around 2,100 officers, officer specialists and warrant officers, military personnel and civilian's workers.

On an annual basis close to 3,900 conscripts, of which approximately 30 are women volunteers do their military service in the navy. In addition about 3,400 reservists are trained yearly in naval refresher courses.

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.
