I have had the boat hauled in Guaymas and Mazatlan on coastal Mexico
, and lived on board while doing projects. I believe it gets every bit as hot and humid here as Louisiana. For relief, I use a 6000 Btu window mounted air conditioner in the butterfly hatch
of my Panda 40. It takes a day or two to have much effect, but it gets the temperatures down about twenty degrees below ambient outside temperatures, and more importantly the humidity down from 95 per cent to perhaps 30 per cent. Soooo - a 12,000 Btu unit in a Westsail 32 will be more than enough....
