Though I do not live aboard, I do keep a cat in the water
and do cruise
and live abord for short periods during the winter. Some thoughts:
Get an IR thermometer and scan the inside of the boat when it turns cold. Heat leaks
in boats are much differnt from houses, and you are just guessing until you scan and find the cold spots. On my boat, the big losses are:
* Windows. Though they are water
tight, they are not double glazed. They lose heat 10-30x faster than other hull
areas. Add storm windows (cut lexan
sheet to match the size of removable screens) or external covers), as apropriate:

* Floors and bridge deck
. Carpets are easy. In general, with cats the floor is not far below the waterline. I would throw cheap
padding under them if I was living aboard
* Roof. VERY LITTLE LOSS. The roof is about 1 1/4 foam sandwich with a linner inside that.
*Hulls. Less foam, but still, little loss.
* Doors. Most cats have very leaky doors. Weatherstrip and insulate. I also hang a big beach towel over mine.
* Close-off areas you arn't using, allowing for some ventalation.
* Do go in all of the lockers with some frequency and let them dry; because you will be adding moisture you are likely to get some condensation somewhere, where there is a cold surface.
* Don't run the stove too much; though the heat seems nice, the CO is a problem and so is the moisture. And get a CO monitor
; I prefer the cheap battery
operated stand-alone units, since event the fancy ones are destroyed if they get wet.
Figure out a way to keep the smoke stack for the heater clear of snow. ALWAYS check after a snow. IF the heat was turned down just a little at night, it will get burried.
I don't see how you cover it and motor
to the pump-out.
Some of your water system runs in un-heated compartments. You may have to blank something off, or get some heat into those areas.
I do hope you have a big hard doger. Snow in the companion way sounds like a pain.
I don't see how you motor
to the pump-out if the harbor freezes; better get local info since this is quite variable (depends on salt
and tide). However, in our area, nearly as cold, the pump-outs do function all year.
Getting tap water can be a problem. They will turn it off, so you may have to lug it.
Get a good plastic folding car-trunk shovel; won't scratch the deck
and just the right size.
And some other thoughts:

I find the boat comfortable in the winter. However, most boats were designed with summer in mind, so you just need to re-think it as though it were a house getting ready for winter.
