Cyclone FC 31-35


Cyclone FC 31-35


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

The vessel has the typical Cygnus construction and performance for demanding offshore use. The combination of dead rise and a more gradual forefoot will cut down on slamming and give a more comfortable ride.

The Cyclone’s 3.8 m 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. This model competes successfully with catamarans. The wide deep V hull provides great buoyancy enabling it to carry a good load.

Most commercial operators prefer a single engine, with protection for the propeller behind a full-length keel and enclosed skeg/rudder. However, twin engines can be fitted. 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.
