Hi All - I'm wondering if anyone on this forum has advice on the best place to install a self-contained marine air conditioning unit on a 1980 ODay 30. I'm currently considering port-side settee, locker, or under V berth for the unit itself. I am looking at approx. 10,000 BTU units with a footprint of about 18"x12" and height of 12". A contractor quoted me 7K for the unit and full install, but I figure I can do it myself for 1,500. Any advice on where your unit and vents are on this boat, installation or sizing tips would be much appreciated!
