King Marine A/C
Our 28.5 came equipped (previous owner) with a 9000 btu King Marine A/C unit. It will flat out freeze u-out! It was installed in the area below the companion way step, with more than adequate room. The vent/return was installed on the next step area and has continued to work great (especially in coastal SC - humidity, etc). The intake (H2O) was connected to the raw water intake for the engine, and is supplied by shifting the L-valve for engine/A-C. It is intended for only dock-side use, but is capable of generator source. We have stayed on the boat for a month at a time in wonderful comfort. A 85-90 degree day with hi-humidity is a cinch, and it has worked flawlessly. The overboard is routed thru the head-area sink plumbing, with condensate routed to the bilge via the shower/head slatted flooring. Good luck...cool and comfy in SC....Cappy
