Hi Jay. Winters and summers pretty moderate around these precincts west of the Cascades. Prevailing ocean winds and water help to moderate our climate. Seldom get a hard freeze (below 20 degrees) during the winter. Some snow, but usually gone in a day or two. We've done several winter cruises with the furnace on around the clock to keep the boat warm. Some even in the snow. No need to winterize the engine, tanks, etc. We keep a space heater on while away from the boat to protect from an unexpected cold snap and also to help keep mold at bay.
Pump outs and dock water will shut down during a cold snap, but then turned back on once it passes in a few days. Our winter cruises usually last about a week, then back home. Either way, we keep the dingy stowed the way I described in my article. That way no need to deflate and haul it home for storage, then back to the boat to inflate all over again.
