OK, so I'm a newbie and this is my first summer owning a boat, but when she's been shut up all day because I'm at work and no opportunity to give her an airing, it is absolutely unbearably hot when opening up late afternoon. She's 52 foot long, fully portholed and none of them open. She has fore and aft hatches, one side hatch roughly mid way, one houdini hatch, one pigeon hatch and only two mushroom vents. If there's no breeze at all, it's still staggeringly hot inside and I'm suffering...
I'd really love to know what nifty ideas folk have found for cooling the boat interior down quick enough to not need 5 cold showers before 7pm!! I'm trying not to be a wimp, but does such a thing exist as aircon for boats, for the rare, but possibly increasing likelihood that we will have 35 degree temperatures in the near and long futures? As this will be my home, I'd like to be a bit more comfortable.
Please
Thank you! K
