Question your motives
Rick,We have a 40.5 with a 5KW genset located in the starboard aft cockpit locker. We installed it ourselves because we are on a mooring all summer and we always anchor when cruising. We wanted the capability to heat water, recharge batteries, and run the reversible A/C cooling/heating units. If we didn't need AC power, we would not have a genset. I suppose that a small 12V generator could be useful, but why put in such a unit when you still would have to run the main engine to make hot water?We don't have a watermaker but would consider one if cruising to places that water is hard to find or expensive. I have heard (heresay alert!!) that watermakers should be run everyday in order to keep them in good condition and to reduce the problems of bacteria and fungus. I may have stated this wrong, but there is some operating problem that attacks the membrane and requires constant maintenance and attention. Bottom line - a watermaker would not be a good choice for a weekender and/or summer cruise person, but would be best suited for a long-term live-aboard in the islands where water supplies are far between.Everything requires maintenance. Lots, unfortunately. I would only install equipment that I really needed, not just to have it. I would install the generator, windlass, electric halyard winch, big batteries, and all the other 'stuff' again without hesitation.BTW, we replaced our factory original cushion material with a high resiliency foam and are much happier. About 25% of the cost of a custom mattress.Also, the 40.5 is an awesome boat! It charges to windward! Great choice for moving up, IMO.There. Was that worth 2 cents?RichSYBARISWesterly, RI
