My 36 XL/kcb has essentially zero space to run AC ducts, although the initial installation did run some from the AC installed in my starboard cockpit lazarette--this was such a tortuous route that there was little air flow into the any cabin! My solution, especially for our racer-cruiser hulls, was to vent the AC output directly into the head thru a ~ 6-8" hole I cut into the shower wall. This, with a louvered plastic cover, directs ALL the AC output direct thru the open head door into the main cabin, keeping it nice and cool, with only two 90 degree bends and no reduced diameter duct work. The return is thru the door into the aft cabin and back to the AC input via a screened opening from the starboard side of the aft cabin. Basically I have no ducts, good air flow and nice cooling with my 16KBTU unit in my 36XL. Those with boats with similar challenges regarding space for ducts might consider a similar solution, especially if any duct work is difficult. Getting the duct work to 1) a particular place is important but what you really want is 2) lots of cool air flow. If 1) prevents 2), you might be better off to forego tortuous duct work and just '...let her rip...", especially in our 30-40 ft boats. YMMV Charlie NelsonWater Phantom1995 C&C XL/kcb

The installer claims, once installed, the main cabin will be comfortable and the aft cabin will be VERY cold. I didn?t consider under the v-berth as there?s a lot of storage that I use down there and, as far as I can tell, venting the other cabins will be a challenge. As for under the steps, I think getting AC-power there would be a challenge and I have concerns, though probably unwarranted, about hoses and wiring interfering with engine access. I?d be interested in seeing a diagram as to how you ran your lines. The head uses a sea-water intake, so I suppose I could tee off of there, but that?s quite a long run, is it not?
