Balance of Power (Seahorse Magazine – Feb 2020)

When it comes to energy systems, Gunboat's William Jelbert talks about what it means to build the most efficient boat possible in this feature for Seahorse Magazine. "When designing a lightweight cruising catamaran we are faced with some tricky problems to solve: conventional propulsion or hybrid, how much solar and hydro generation, how big to go on alternators and battery banks… and where do we anticipate the next jump in efficiency, size and weight savings? Then there’s the issue of how we accurately spec for power demands on a luxury, large performance catamaran, with all of the amenities, keeping weight-sensitivity and maintenance in mind, with the appropriate number of redundancies and amount of reliability… and decide that the system is ‘optimised’?"
