It all depends on how good your insulation is. My power use is quite conservative but it's about 80 - 100 amps a day. 90% of that is the fridge. So you might get 2 days out of your batteries but the problem is how are you going to charge them? The wind generator will have a hard job keeping up in the Bahamas. You will need another source. A Honda 2000 is good but that won't work well if you only have a 20 amp battery charger, as most of these boats have. It would take the Honda over 10 hours to get your battery bank up if it's down 50%. To get the most out of the Honda you need a 100 amp charger. You see how the fridge is just the start? Holding plate systems are falling out of favour. An evaporator type is preferred. I have both types (holding plate on the CS) and the top loading Adler Barber freezer (evaporator plate) with spillover to a small front loading fridge (on the 393) works very well. I can keep ice cream hard, can't do that with the holding plate system.
Toronto in summer, Bahamas in winter.
