I am always impressed by the broad range of experience and expertise that

this discussion group seems to attract and retain, so I decided I would put

a question out and invite all to ponder and respond.

I am working on a project involving the eco-enhancement of a fleet of 19'

Boston Whalers to allow the operator to opt to propel the boat using an

electric drive when there is no need to be up on plane. I have chosen the

36-volt Lenco Dual Digital propulsion system since it would work seamlessly

with the existing 150+ HP gasoline-powered outboards and complement them

rather than compete with them, as well as add the trim tab functionality.

When off plane, it would be a simple matter of turning off and tilting the

gas motor up, lower the Lencos and switch operation from helm steering to

the JoyRide T joystick. Quite simple and effective as I see it since

neither system will interfere with the other.

The question I pose is that we probably need to look beyond lead-acid since

we are trying to limit the overall weight increase of this parallel-hybrid

system. A 200 amp-hour, 36-volt nominal battery pack would be considered a

minimum. We are also concerned about battery longevity as they will get

tossed around quite a bit in the open waters on full plane and subject to

vibration and other environmental hazards. Cost is certainly a factor, but

not the dominating one.

Any thoughts on this out there in e-boatland?
