Geraldton-based Dave Perham, a highly experienced operator from Australia’s Western Rock Lobster fishery, has taken delivery of a new lobster boat from Dongara Marine that’s proven to have much lower fuel consumption than comparable vessels.
Completed in late April 2020, some 12 months after contracts were signed, Force of Nature is a 22.4 metre Southerly Designs monohull which, like other recent Dongara Marine fishing and pilot boat newbuilds, combines an aluminium hull with a composite superstructure.
The new boat is an upgrade from Perham’s current vessel, the 17.1 metre Conquest 55 Natural Selection, which was built for him by Sea Chrome Marine in 1994 and which Perham is selling to make way for Force of Nature. For example the live tank capacity for 84 baskets of lobsters is a considerable step up from Natural Selection’s 64 baskets.
Onboard facilities meet the AL36-72 specifications in the National Standard for Commercial Vessels (NSCV) enabling the vessel to remain at sea with seven people onboard for up to three days. This entails equipping Force of Nature with features that are not required at the lower survey standard of a typical day/overnight boat.
On Force of Nature, twin Scania DI16 076M engines rated for 662kW (900hp) at 2300rpm each drive a fixed pitch propeller via a ZF gearbox. On trials this combination gave the fishing boat a maximum speed of 24.5 knots and 18.5 knots cruise speed, each about 1.5 knots above expectations. This performance was achieved with the boat’s 7500 litre fuel tanks full
