Steve and Deb,
HI..I see the CruiseAir's all the time on Craigslist. Go to SearchTempest.com and enter the keyword CruiseAir and air conditioner in the search box, and use Boats for sale as the base search.
Hi, I use a CARRY ON ,for Hatches and tie it down, and sail with it.
I also use a fan to pull the cool air from the front v berth when I'm running it.
I got it on Ebay.
I also know a sailor who installed an RV air conditioner...made to sit like that...Those really Cool.
All these are if you have Power at the dock, or convert them.
