First, remodeling an older boat can be a very expensive proposition, especially compared to buying a 30' sailable boat in decent shape. What is your budget for refurbishing/remodeling this boat?
Given that your boat has some serious issues—a non-working Atomic 4 engine, a dated electrical system due for overhaul, no working fresh water system, serious leaks in the cabintop and deck, a rotten main bulkhead, etc.—I personally think you'd be better off using a different boat.
BTW, The OutIsland series of boats were not designed as bluewater boats IIRC, but more as a coastal cruiser.
I'd also mention that for a cruising sailboat, electrical propulsion is probably not a wise idea.
This is for several reasons. First, an all electric propulsion system is fairly complex and expensive, and not all that reliable on a small sailboat. Second, the inability to quickly recharge the batteries makes the all electric propulsion a liability in heavy weather, since the engine could easily quit and leave you without propulsion at a critical moment. Third, an all-electric propulsion system is very difficult to keep charged without a very massive solar/wind passive electrical generation system—which is why some cruising sailboats have gone with a hybrid, diesel-electric solution instead.
I also doubt you have six 950 amp-hour AGM batteries aboard. An 8D AGM battery supplies 230 amp-hours and weighs 170 lbs. One that supplies 950 amp-hours would weigh close to 700 lbs, and you claim to have SIX of them aboard or 3500 lbs. of batteries... I SERIOUSLY DOUBT THAT IS THE CASE.
As you are fairly new to sailnet, I would highly recommend you take a moment and write down as much accurate information about your boat as possible and give as much information about your plans and goals as well as the resources you have to accomplish them before continuing any further. For instance, providing the make/model of battery would be far better than just making wild-assed guesses as to what you have. AFAIK
, there isn't a 950 amp-hour battery made for the marine market.
Also, what skills in terms of boat repair, fiberglassing, mechanical, electrical, plumbing and such do you personally have to bring to your remodeling project?
