On my Mark I, I installed the Dometic Turbo 16,000 BTU in the locker forward of main salon table, ran one large duct thru the v-berth hang locker and hole in the top/shelf of locker where installed a nice wooden box with vents to direct air to main salon and v-berth.
The unit cools down the entire boat, including the aft cabin, since salon vent points toward the aft cabin door.
This unit has a sound cover over the compressor and a relatively small foot print. Sound / noise control was an important consideration since my wife would not have tolerated a loud compressor, I was willing to pay more for this unit.
The boat is located in Maryland where its quite hot and humid in the summer and it works so well that we sometimes get condensation on the outside of the boat like a beer bottle. I've wondered if I could have gone with a 14,000 BTU unit instead. Heat side also works well too but I really need to install a vent a floor level. Also installed a soft start to use with a portable Honda generator.
