Hi Crazy Talk:
I lived on board full time in Port Credit Ontario
for almost 9 years without a problem at all. Quite simply, I shrink-wrapped my boat with clear plastic (good for the warmth on sunny days) and hung a bubbler underneath to keep the ice down. The plastic worked so well that I was able to do all of my spring woodwork (cetol mostly) in late February and early March. Once the winter cover came off, all I really had to do was "hang some rags" and go sailing.
The trick with heaters is to use the oil
filled or baseboard style of heaters to get the most efficient use of power out of them... boat was always toasty warm. The other simple trick is to use an electric blanket, set on low, UNDERNEATH the bed sheets
. I guarantee you, that a team of horses will have a hard time dragging you out of bed in the morning.
You will still have to do the usual winter lay up stuff to your boat, plumbers antifreeze thing for the head
, antifreeze for your engine
, if it's raw water
cooled and close all through hulls.
Other than that, just keep your dock
clear of snow. If your marina does freeze over, have a 2x4 handy to break up any ice that the bubbler may not get at.
