cat-a cism, I agree completely with all of the comments above. The size and weight of the house battery bank that you are proposing (as well as the size of the solar panels
and size and weight of the wind-generators) are just not realistic in the boats that you are considering. Furthermore, as has been pointed out, electrics and plumbing
etc. should be secondary considerations, at best, in selecting a suitable boat for your purposes.
Comparing the boats you mention: I think Richard Wood's designs are terrific and would likely provide you with better overall performance than the Prouts and Geminis to which you also refer (bearing in mind that when not overloaded, the Gemini
105 performs quite well but for the effects of the minimal bridgedeck clearance). Build quality is another matter entirely, of course.
The quality of construction of the Flickas could vary widely. Was it an amateur build, or one done by a respected yard? In either case, what does a visual inspection
(let alone a mandatory survey) reveal about the level of skill of the builder
, the materials used, etc. The Prouts were, for the most part, well-built boats with proven longevity. Having said that, the bridgedeck clearance is also very low, performance to windward is relatively poor and, if considering the early double-enders, relatively poor even downwind. The Geminis, as already mentioned, actually perform quite well in most circumstances. However, they are plagued with stress cracks and are known to pound, even at anchor
Have you considered the PDQ32? A bit more money
than most of the older Geminis and Prouts, but an extremely well-built boat with good performance and decent bridgedeck clearance.
