My compressor is installed just forward of the water tank in the vberth including water pump thru hull and discharge. the evaporator filter is located in the starboard side cubby hole at the front of the v berth. the air duct runs through the hanging locker and exits thru the top of the locker into a dual grille outlet teak box with a small vent to the vberth and a larger vent thru the bulkhead into the main cabin.Hope this helps, you can email me at gm18sail@aol.com.Do you have refrigeration and if so how do you like it and would you do it again?thanks, gerald "tranquility"
