A week ago I finished installing an ac unit into my classic r27. The unit is made by marine air and has a capacity of 6000btu. The install was relatively easy. The main unit was shoved under the companion stairs with hoses going along the floor which is easily accessed from the cave after removing a the small panel along the floor. Power was already there just had to connect the wires to the power panel after fishing for them. The most painful part was to drill a hole into the hull even so it was above the waterline. Cold air exit is on the center facing upper stair with a grill that can be rotated to redirect the airflow. Main water pump is mounted on the ledge behind the poop tank. Main unit is mounted on a marine quality 3/4 plywood that is glued to the space under the stairs and then the unit is screw to that board. Control unit is mounted on the wood section leading to the v berth. A remote is also include. The marinaire is a reverse air ac providing cold and hot air.

Unit was working flawless keeping the boat cool inside at 97 outside. Covering the windows is essential to keep excess heat outside.

The marinair unit is about 1200 plus 200 for the pump and a few misc parts to get everything connected like hoses, clamps, in-line filter, shut off valve, wire and screws and thruhull exhaust and air register

Took about 5 hours install after trying a few places. Helps to have second person to get things while submerged in various cavities on the boat

Very pleased with install, most work done by my son climbing into those spaces, and helped tremendously at a cruiseout last week plagued by smoke in the air from all the fires. Made it comfortable inside while the smoke was lingering outside.
 
An A/C install in five hours is impressive!
 
R27 is a small cabin. Works out just fine. Important part is that the unit can be powered by a small portable generator if needed.
 
Smaller BTU does help with a portable generator. I see you are in California so maybe less humidity and not as hot as the southeast. That small amount of BTU's wouldn't cut it here.
 
What update did you have in mind
