retro fitting ac system in modern classic sailboat

good evening all.i just took over a beautiful 3 year old aluminium dutch sailboat.everything is great except there is NO ac system and we are in the caribean.i had 24v caravan type ac units on the flybridge of an old boat i ran.this boat is set up to run on 24v but dont think the owner wants to see the things on his classic style deck.any other 24v units that could be put under the sole or anywhere where they wont be seen?any units that dont need sea water circulation?would love to find something small,maybe broken down into componets like some watermakers.
thanks for any ideas.
spell checked twice because last time i posted i got chastised for my speelng.
