Sorry about the error! I meant to write under Starboard side cabin seat. All AC Volt Marine air conditioner pumps have to be installed below the waterline. The AC pump that I used is a CAL Marine 580 Gallon per hour with a vertical lift (head) of 9 feet. I'll post pictures as soon as I can figure out how to do it.
I don't know how to attach the photos on this apple of mine....I do from my office....I don't think the Mermaid would fit on an adapted shelf as you describe...I truthfully did not measure for that and I wish I had...although, the least of my problems were the location of the condenser under the v-
berth. I came out of the Mermaid w/ a 6 inch duct which looking forward comes out the left side. After about 8 inches Installed a two duct dividers (that's not the professional term) and took two 4 inch ducts thru the bulkhead to behind the sink and up thru the vanity where I split the four again to make 2 port ducts into the salon.....back to the 6 incher...I divided the 6 incher twice - the second under the v-berth then up thru the hanging locker to another divider that sent one 4 inch duct to main salon on the starboard, and one four inch duct into the v-berth......just too many turns.
I had sent drawings to Mermaid well in advance of my order and there was never any mention of all these turns just being too much.....What it causes is the unit to have to work too hard to get the air thru the system....My vent
air-intake is installed right under the v-berth cushion the Mermaid 12 x 14 inch vent attached to a 1/4 inch smoked plexiglas, which is attached to the
base of the forward wook bulkhead. Mermaid sells a 1/2 inch line and a brass item called a condensator that automatically removes all the condensation from the pan when the unit is running and sending fresh water overboard......It was the best extra I installed. The pressure of the fresh water running overboard sucks the condensation overboard.... If I were to re-do this I would have just sent 1 6 inch line /duct to the main salon somewhere....the problem was where to find the additional space on the bulkheads, both port or starboard....I have too much stuff on the wall/bulkheads....If you reply with an email address I can send pictures....but we've had this boat 25 years now so it's pretty lived in.....If you want to see pictures of our club, etc. go to

It's a fabulous home away from home 9 months of the year....
