UK boatbuild expert Cheetah Marine has delivered a newbuild catamaran to the Geological Survey of Ireland (GIS) Inshore Mapping Programme.

The 7.9m RV Tonn, will map areas of seabed around Ireland and follows on from two similar specification Cheetahs developed for the Port of London Authority and the British Geological Survey.

Archie Donovan, Principal Geologist & joint INFOMAR project manager, said: “The RV Tonn is a proven shallow water survey boat, that has been built to the Cheetah Marine 7.9m specification for the Geological Survey of Ireland's inshore Irish mapping programme. We in the GSI, look forward to continued collaboration with Cheetah Marine, on our future survey boats.”

RV Tonn features Cheetah Marine’s patented Hydropod system which enables high resolution surveying to be carried out at relatively fast speeds of 6 to 10 knots. The system can accommodate various transducer heads and in this case is designed to house the Reson Seabat T20-P.

Powered by twin Honda 135hp engines, the RV Tonn has a cruising speed of 16 to 18 knots and a top speed of 25 to 27 knots. Inbuilt 150 litre aluminium fuel tanks on each side give the catamaran a range of up to 150 miles at cruising speed.

The long wheelhouse features a port side work station above 19” rubber mounted computer racking, a starboard side bench and suspension seating forward.

All stainless steel work, including surrounding safety rails, folding roof mast gantry and keel bands was fabricated in house by Cheetah Marine. An aft frame in 50mm stainless steel tube ensures a strong and highly accurate GPS Aerial fixing position.

On the aft deck is a Honda 2Kva generator in a moulded box supplies the extra power required for surveying.

The navigation package supplied by Simrad is complimented by the NMEA Backbone, displaying real time engine performance data critical for ensuring optimum cruising speeds between survey sites and on long transits.

RV Tonn is surveyed to comply with the Irish MSO Build Certification P6 Passenger boat for 6 persons.

Cheetah Marine is now celebrating 25 years in production and has just launched the next generation 6m series.

The new series offering more deck space and a greater load carrying capacity has been designed to take advantage of recent advancement in outboard engine technology. The 6m series has been popular amongst harbour authorities and hydrographic survey companies as a trailerable survey boat.

The firm will be exhibiting two catamarans on the pontoons at Seawork this year. Both vessels have been built for specific survey and workboat purposes demonstrating Cheetah’s approach to specialised one off builds.

Visit Cheetah Marine on the pontoon at Seawork International on berths V50 and V51.
