Hi everyone,
I personally understand how it feel to have a limited range vehicle as I've worked with electric vehicles and driven them pretty often. I think the nature of boating is to be free from any constrains and to be-able to go anywhere the sailor wants. If my client only needs 40mile range usually, but all of a sudden he decides to go out for a week's cruise and will need more motoring range, I don't want to all of a sudden be the one who said "look you don't need that extra range". He'll regret spending all his money because He is now constrained.
Chris,
What is keeping you from putting solar panels on and in-between the side hulls of your trimaran? Where the trampolines are? Are the trampolines there for a airflow functional purpose or something?
Regards,
Ricky

> Solar is great when you're not on the boat, and marginal when you are. It is just so hard to attractively harness enough electrons with such small deck area (Current Sunshine has done about the best of which I'm aware). Wind is the sailboat's best friend; harness it with sails AND a towable generator OR with a deck mounted windmill alternator when docked.

He is willing to go for the latest lithium, solar, and wind technology. He basically want this boat to be 100% green with not a single drop of fossil fuel needed.

It has a 210L diesel fuel tank. how long does the 210L diesel fuel last usually? What is the energy needed to propel it to a reasonable speed?
