Air Conditioning and Heat
Air conditioning and heat is a bit of a luxury on a small yacht due more to its high power draw than to its cost. Marine AC/heat sells for as low as $1,300 in an 120VAC unit. The maximum power draw is just under 550W. This would require an upgrade to a higher capacity inverter at nearly $1,000. There also may be a challenge (possibly insurmountable) finding room for the unit in the forecabin.
Whether AC/heat is installed at a cost of about $1,300 (plus a roughly $1,000 upgrade to the inverter) depends partly on how much sailing is done in the tropics or in Maine or Canada and how uncomfortable this gets. It also depends on whether room can be found somewhere in the forecabin for the unit which measures 11.2" L x 16" D x 11.6" H. Right now there is room in front of the holding tank but this is a poor choice. The holding tank could be moved forward but would require cutting into a bulkhead and then reinforcing so as not to weaken the structure. A last resort is to use space aft and run long air hoses.

forward space can be used for the AC/heat system.
the Mabru fits easily. the Webasto fits but needs new access.
it may be worth separating this area from the holding tank space.
this could be an enclosed area accessed from top.
the space aft of the holding tank might be useful for a water heater.
a new access could be made thru the v-berth (at least 24" x 14")
the existing water heater could be used and be close to shower
sides of aft "potential access" needs to be measured again.
this space is trapezoidal so large rectangle might be an issue.
