A seabed debris clearance, environmental baseline and habitat assessment site survey will take place in licence SEL 1/11 (Barryroe) from later this month.

Barryroe is located in the North Celtic Sea, some 50 kilometres south of the Port of Cork.

The project is scheduled to commence in mid-August 2019 with the survey vessel Kommandor (callsign MCJO2) anticipated to be working on location for 16 days, excluding transit and any weather delays

Survey operations will be conducted on a 24-hour basis in different phases to include towed and non-towed operations. A fisheries liaison Officer will be on board for the duration of the survey.

Throughout the survey operations, the vessel will be displaying appropriate shapes and lights to indicate that the survey vessel is restricted in its ability to manoeuvre.

All vessels are requested to give this operation a wide berth. A listening watch will be maintained on VHF Channel 16, and the vessel will actively transmit an AIS signal.

Full details of the site survey co-ordinates are included in Marine Notice No 27 of 2019, a PDF of which is available to read or download HERE.

Published in Offshore

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.
