#NavyVisits - HNLMS Walrus which is one of the world's most sophisticated submarines arrived in Cork City yesterday for a courtesy visit this weekend, writes Jehan Ashmore.

The non-nuclear powered submarine is the leadship of the 'Walrus' class which was commissioned in 1992 for the Royal Netherlands Navy. In total there are four of the class and they are the only submarines of the Dutch Navy but play a pivotal role in operations.

HNLMS Walrus entered Cork Harbour in the afternoon. From within the expanse of the lower harbour, the 68m submarine navigated further upriver through Lough Mahon before making the final leg to the city's central quays.

According to the Dutch Embassy the visit to Cork is for the purpose of crew rest. Embarkation of the 50 submariners is from J.J. Horgan's Wharf on the north bank of the River Lee. 

On this occasion, the Dutch Navy will not be on training exercises as previously conducted by a pait of fleetmates, albeit surface ships that visited Dublin last month. This involved a Landing Platform Dock (LPD) amphibious warfare ship and a frigate that took part in exercises off the east coast with the Irish Naval Service OPV L.É. William Butler Yeats.

The diesel-electric powered HNLMS Walrus has 4 torpedo tubes incorporated within the stealth designed submarine. Such technology is to make it more difficult to be detected by ships, aircraft or other submarines when deep under the ocean waves.

At 2,650 tonnes displacement (when submerged) HNLMS Walrus can remain under the water surface for long periods to enable missions. On overseas deployments, this can include patrolls in the Caribbean Sea with calls to Williamstad, the capital of Netherlands Antilles.

On this side of the Atlantic, the berth allocated in Cork for the submarine's visit as alluded above is where a sister HNLMS Dolfijn paid a call in 2016. That submarine did take part in exercises witht the Naval Service. 

HNLMS Walrus will remain in port until Monday morning.

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.
