Re: Mist Cooling System
I wouldn't think it would be too hard to make. You would either need to pressurize the water and send it through a nozzle, or pump it into the back side of a fan (both would be ideal). While it it would be easier to me to just jump in, I could see it being better for people that don't/don't want to swim.
Thinking a little more, I think the ideal way to do it would be to have a flexible tube run around the perimeter of a bimini top, with multiple nozzles around. As long as the mist is fine enough and the day is hot enough, I don't think you would have any problems with too much water in the boat.
