#multibeam – A new multibeam sonar system fitted to the Marine Institute's Research Vessel Celtic Voyager will allow a new level of detail of seabed features to be captured during important mapping surveys around our coast.

It will greatly increase the capability of the vessel to acquire seabed bathymetry data as part of the INFOMAR seabed mapping program and other projects.

See how the new sonar operates in the promo vid below.

The new EM2040 system will be the primary mapping tool during upcoming INFOMAR survey operations offshore County Galway, Clare, and West Cork, extending the Irish seabed coverage around our coast.

This seabed mapping activity will support ocean energy development and fisheries management, and provide improved navigation for safe shipping and transport.

It was successfully installed onboard the RV Celtic Voyager during a recent dry docking in Killybegs, Co. Donegal.

The EM2040 system which was purchased from Kongsberg Maritime was installed on the vessel at the Department of Marine shipyard in Killybegs by P&O Maritime with the assistance of Mooney Boats of Killybegs.

This system replaces an older system which has been in use since 2000.

About Quarter Tonners

The Quarter Ton Class is a sailing class of the International Offshore Rule racing the Quarter Ton Cup between 1967 and 1996 and from 2005 until today.

The class is sailed by smaller keelboats of similar size and is likely the world's most-produced keelboat class.

The Ton, Half, Quarter, etc. 'classes' were each given a 'length' and yacht designers had almost free rein to work the hull shapes and measurements to achieve the best speed for that nominal length.

The Ton Rules produced cranky and tender boats without actual downwind speed. Measurement points created weird, almost square hull shapes with longish overhangs.

They were challenging to sail optimally and lost value very quickly as any new wrinkle (e.g. 'bustles') to take advantage of the rule made older boats very quickly uncompetitive.

Although its heyday was 30 years ago, the boat class continues to make its presence felt by holding its own in terms of popularity against some fern race fleets.
