Cyclone FC 31-35


Cyclone FC 31-35


The Cyclone 31/35 is intended for use as a fast workboat with applications for passengers, chartering, commercial fishing, angling, survey, patrol and leisure use. The standard forward control wheelhouse has been designed along the lines of the original Cyclone 30.

It can be extended for other applications like the charter & workboat market. The vessel has the typical Cygnus construction and performance for the demanding offshore use. The foredeck and ring deck are cored constructions for strength and stiffness. The combination of dead rise and a more gradual forefoot will cut down on slamming and give a more comfortable ride.

The Cyclone’s 3.8m moulded beam, with the addition of the familiar wing type chines carried right below the waterline, provide very high stability for this class of vessel, at rest or on the plane and this model competes with catamaran boats. The wide deep V hull provides great buoyancy enabling it to carry a good load without excessive increase in draft and loss of freeboard.

Most commercial operators prefer a single engine, with protection for the propeller behind a full-length keel and enclosed skeg/rudder. With either single or twin diesel engines, usually straight shaft drives, a maximum speed of 25 knots is achievable with a comfortable cruising speed of 14-18 knots.
