We have one of the cruise air hatch units bought 6 years ago. It stores under the filler of our V berth when inderwya. We always have a breeze when anchored out, but in our slip or when traveling it has been the difference bewtween us using the boat or not.
It stows easily never moves aorund underway, and is never in the way as what goes under most people V berth fillers?
We have a rountine for ptting it in the front v berth hatch. We have amused people in marina we have stayed in as my wife and I have a 5 minute choreographed routine. Open the hatch. She gets the spinaker halyard. we attach it around one of the units handles ( it weighs 70 pounds but is bulky and unweilding to lift or carry). She cranks the halyard around a winch while i guide it up through the hatch it emerges from below and the drops right into place. 5 minutes tops. Runs on 110 AC from one of the boats outlets or off a 30 adapter cord off of a 50 amp splitter. We were thinking of even getting a small HOnda quiet EU2000 and running it at anchor, but quite frankly have never neede it at anchor. Why sweat and be uncomfortable, it has allowed us to go to our boat every Friday evening and cools our 35 footer fine.the V is like an icebox Hella fans bring the cool air to the rest of the cabins. When the unit dies I will probably put a marine reverse cycle on in with ducts.
