I thought that is why this forum exists? How do you solve a problem without asking THE question?

Most knowledge is gained from asking a question.

SERIOUSLY!?


The question was is it practical.

For some people it is. For others it is not.

Re: running my ac on the hard

Your water cooled a/c won't work on the hard unless you use a 55 gallon drum, with a lift pump. And you have to consider other factors - ambient air temperature and size of your unit being only two. Sounds complicated.

Getting up and over an a/c unit in the main hatch is awkward, at the best of times, and not friendly to the ladies.

I mounted my window rattler above a deck hatch and led the drain outboard. Sealing against rain required some thought and experimentation - a one time deal.

For a 42 ft aluminium boat, the yard told me 10-12k bthu unit was necessary but, on my boat, this is overkill and unpleasantly, puts all the cold air in one spot.
On my boat, 5-6k works well, with a 16" multi speed oscillating fan, which is essential for livaboard, and easy to direct cold air.

Addtionally, a 5k unit is smaller, much lighter and stows in the "garage", ready for the next haulout.

Metal boats may require more a/c capability than a glass boat, but metal boats are typically insulated from waterline to waterline, which few glass boats are, so it's probably a wash.
