#MarineScience - The new mission to Ireland’s offshore reaches to monitor seismic activity on the North Atlantic floor is to engage with schools while at sea.

As previously covered on Afloat.ie, scientists from the Dublin Institute for Advances Studies (DIAS) departed last Monday 17 September, on board the RV Celtic Explorer, for the three-week voyage that will see them deploy a network of 18 seismometers as part of the SEA-SEIS project.

Daniel Farrell is reporting on their work via the RV Celtic Explorer’s blog [email protected].

“I am looking forward to sharing first-hand what it’s like being on a research vessel such as the RV Celtic Explorer,” says Farrell, of CoastMonkey.ie and sponsored by DIAS and the Marine Institute.

“I have a passion for the sea, and will be filming the scientists, writing content for the blog as well as taking photos of all of the activities where everyone can keep up to date with what is happening.”

Students and teachers can engage with the mission through Farrell’s blog posts as well as with a range of resources and videos available on the SEA-SEIS website.

“The SEA-SEIS team have also organised a range of activities that both primary and secondary schools can take part in over the next couple of months,” Farrell adds.

“There are teaching resources and lesson plans from the Explorers Education Programme, as well as some great competitions involving a drawing competition and composing a rap song.”

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.
