I did once in Ft Pierce. Took a couple weeks back in the water
for one door to shut properly. I only had a couple screened ports
and louvered/screen companionway
doors for ventilation. It survived. I think it was too damn hot for mildew! I left the boat in June and it was too hot aboard with everything open on the hard
to do anything for more than an hour. If the boat's used to Florida, I dont know that it will be worse off (as far as dampness) on the hard
as on the water. Needs ventilation most.
