Re: Pearson 31-2 - AirCon
Hi! I've got a '88 31-2 in Annapolis also, up Mill Creek. The compartment under the fwd starboard seating, next to the mast (where the transducers are), was sort of designed for an AC unit- it was an option when built- especially being close to the thru-hulls to tie in to. I think if you poke around the old Chesapeake Pearson owners' website there are some examples of retrofit units that fit in there well. Can definitely be a weekend DIY job if you're a little handy. I recall reading that it needed to be very very compact, and may not be space to run any ducting to other parts of the boat- would be direct discharge.
I'm considering adding an AC- only have a dehumidifier now- would use a portable AC and strap it on the deck against the port side of the mast (still plenty of room to walk by to the head/v-berth), and run the exhaust duct to the dorade vent over the table. Being right by the head, probably snake a condensate discharge line into the shower pan versus the bilge (I like to keep the bilge dry). Also can run the power cord to the outlet in the head. Home Depot has some for ~$220?
