#MarineScience - The Marine Institute will host a three-day workshop on some of the latest technology for ocean mapping next month when the CARIS World Tour stops off in Galway from Tuesday 15 to Thursday 17 November.

Information sessions, detailed demonstrations and hands-on software exercises will be the order of the week in an opportunity for the marine science community to learn about the next generation of CARIS software architecture and its benefits to the hydrographic industry.

Topics will include near real-time sonar data processing, variable resolution surfaces, IHO S-100 and related product specifications, as well as updates on the latest tools and features for efficient hydrographic information processing, management, production and discovery.

The CARIS World Tour will be relevant to surveyors, data processors, cartographers and GIS technicians, as well as managers and decision makers who want to understand the latest technology and trends in ocean mapping.

Participants can register to attend one, two, or all three days of workshops. Visit the CARS website to register and view the agenda HERE.

In related news, London’s School of Economic Science is hosting a marine data management and GIS workshop on Tuesday 22 November.

Under the theme ‘Is poor data management putting your operations at risk?’, the free workshop will examine how GIS technology and OceanWise products and services can deliver efficiencies. Register for this OceanWise event 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.
