Mark Stafford here with a similar sailboat: H55 (longer, narrower, electric). Do-able, fairly cheap, quick and easy. It took me much learning and planning, but only a few days of work. Now the bad news: every electron counts. No wasting energy, if you want that performance. 4 knots will more likely be your "sweet spot" in terms of range/safety margin. Use at least eight NEW 6v golf cart batteries (preferably 16). 48V system, gear or belt reduction, optimum prop diameter (15?% prop tip clearance), brushless permanent magnet motor(s). Everyone likes regen, but no-one relies on it: one hour of fast sailing will get you 1 minute of cruise power. More bad news: use Paktrakr, ampmeter, voltmeter, marine GPS, knotmeter, maybe CycleAnalyst and RPMs too. With electricity, you can't make intelligent decisions without information. Can you cannibalize a golf cart? Yes, but expect 1/3rd your desired performance. Arby Bernt and James Lambden are the kings of efficiency, having spent years optimizing. ThunderStruck and ElectricYacht are great sources of parts/systems. There are more: check the "links" section on the left side. This ElectricBoats YahooGroups list is indispensable! You have used it perfectly. FLA batteries are great on sailboats, especially if they are oriented posts-fore-and-aft. The tipping back and forth (tacking) keeps the electrolyte well mixed for even plate charge-discharge cycles. Hydrogen rises (let it escape!). Call me or anyone else. We are here to learn/share.
