Bellmarine converts classic Halvorsen Cruiser on Pittwater

Electric motors and wooden boats are a good combination. Many wooden boats have aging diesel engines, which are often cumbersome and large, taking up valuable interior space and leaving an oily mess in the bilge and a trail of exhaust smoke that often lingers over the boat, particularly when motoring downwind. 

Resilience, a 26’ timber Halvorsen cruiser built in 1967 was originally powered by a 145hp marine petrol engine, followed by a 50hp Yanmar diesel which was noisy and smokey. The old diesel, fuel tank and associated gear were removed and replaced with a 15kW Bellmarine liquid-cooled DriveMaster system, driving the original shaft. The fuel tanks were replaced with a 14.4kWh 48V LiFePo4 Lithium battery, giving her a range of up to 10 hours at 4 knots cruising speed. Top speed is 7 knots. The conversion was carried out by Mako Marine Centre at Berowra Waters.

The battery bank can be charged from shore power, assisted by 3 x 300W solar panels installed on the roof. According to the owner the new Bellmarine motor is about ¼ of the weight of the old diesel engine, much smaller and virtually silent and vibration free. A separate 12V battery bank was retained to run the existing 12V system powering the fridge, lights, pumps, etc.

The Bellmarine electric motor has given Resilience a new lease on life and made her more enjoyable to sail on.
