Displaying items by tag: hydrographic survey

Hydrographic and geophysical surveys will be undertaken in the Irish Sea off the Wicklow coast between June and September 2019 to provide bathymetric and subsurface information to facilitate the development of the Arklow Bank Wind Park.

The survey dates are weather dependent but are anticipated to start in June and be completed by the end of September.

The location of the surveys will be off the Wicklow coastline. They will be completed using two vessels working in parallel across the site. The vessels involved are the AMS Panther (Callsign: 2EHC2), which is a 17m windfarm support catamaran, and the AMS Retriever (Callsign: MEHI8) which is a versatile multi-purpose shallow draft tug.

Both vessels will be engaged in survey operations and will be restricted in their ability to manoeuvre. The vessels will be towing survey equipment up to 100 metres astern. Vessels are requested to leave a wide berth. The vessels will be operating 24 hours per day during survey works.

Details of the survey area and relevant co-ordinates are included in Marine Notice No 11 of 2019, a PDF of which is available to read or download HERE.

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.
