A leading marine science researcher based in Ireland is part of a pioneering mission to explore the depths of the Indian Ocean, as Silicon Republic reports.

Prof Louise Allcock is head of zoology at NUI Galway’s Ryan Institute and has previously led deepwater surveys to investigate corals and sponges in the Atlantic on the RV Celtic Explorer.

Her latest task takes her much further afield, to the Seychelles west of Africa, where she is second-in-command behind principal scientist Dr Lucy Woodall on the Nekton First Descent mission.

Earlier this week the team carried out their first crewed dive to the ‘twilight zone’ of the Indian Ocean below 30m, where sunlight barely penetrates.

The team will be using crewed submersibles and ROVs to explore marine wildlife and plant life at depths of up to 500 metres, while also using sensors to collect data on what lies much further below.

Sky News and Sky Atlantic will be broadcasting live from the Nekton mission this coming Monday 18 March from 8am as part of the Sky Ocean Rescue initiative.

It is hoped the mission’s research will inform science and government policy on a range of issues from conservation to climate change.

“It’s very exciting to be deploying so many different pieces of equipment and doing such a thorough survey of the ocean,” Prof Allcock said.

And she has already been granted her wish to see a sun fish in its natural habitat while on one of the mission’s Triton submarines.

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.
