Default Winterizing Cabin 37' SportFisher in Seattle

Hey Guys,

I've got a 37' foot diesel sport fisher kept in brackish water in Seattle (may have a few days below freezing for prolonged periods over the winter) and I'm looking to keep the cabin from developing mold over the winter. The boat is in a boathouse with shorepower (due to some projects going on at the marina this may be out from time to time this winter). Since we already have had our first freeze I've added RV/Marine Freshwater antifreeze to the freshwater system.

My real questions is on how to approach running heat and/or dehumidifiers in the cabin. Here is what I'm considering doing. Let me know what you guys think.

- Delonghi Oil Filled Radiator in the forward cabin/v birth. (diesel boat)
- Davis air dryers in the engine room that is inside of the cabin with the hatch open.
- Dehumidifier? With our without one of the heaters above?

Obviously my main concern is fire danger from running heaters.

I wish I could help. the only suggestion I can make is, ask your dock neighbors or the marina staff.

I stored the same size boat at Elliot bay for 10 years. The shore power there is pretty good but can go out occasionally. In real cold water I turned on diesel block heaters.
Always left a marine boat heater on freeze protection in the cabin that I purchased at Fisheries. It has a cut off if it turns over (it never has). I never have put refrigerant in water lines.
If the power went out for many days in sub freezing conditions I would turn on diesel furnace. Rare for us to have all of those things happen at once. Usually if wind causes power outages the temps are not sub freezing.
