Where do you go for summer? I couldnt imagine being without the boat!
Do you have a choice to store in the water versus on-land or on-land is safer because of hurricanes?
Window AC unit seems like overkill but I dont know what temps the boat will see. I usually suggest a dehumidifier that drains into the sink as another poster suggested. In fact, you might need multiple dehumidifiers... dont forget about areas such as engine room, storage lockers, etc, although a dehumidifier may not fit you may have to think of other options.
- Raw water intakes… rule is usually to leave open when on the hard. If you expect freezing temps you probably need a bunch of antifreeze to run through everything. You can blow out the HVAC and water system with compressed air. You can't drain the cutlass bearings, I think you are talking about the volvo drip-less.
- Fuel – Fill the tank (is the weight a problem on blocks for 6+ months)? Use Stabil Diesel stabilizer/anti-algae? Diesel is much more stable than gasoline. Most wont add anything if they plan to use the boat in 6 months. Don't add stabilizer to stale fuel, only fresh fuel (and make sure you read the instructions!)
- Water Systems: I'd drain everything, blow out with compressed air. Water tanks are a total PITA to fully drain but you can use a shopvac to get most of it.
- Septic – Pump it empty and add deodorizer… Anything else I should do? pump it empty, add some dawn and water, go for a spin, pump it all out.
- Electrical/Batteries: my boat is plugged in 24x7 except when we are out cruising. Make sure if you have wet batteries that someone is maintaining the distilled water levels.
- Mold prevention – any tips. Should the window AC unit do the trick? Keep all cabinets, drawers, interior doors open. I put damprid buckets in compartments, lockers, hanging damprid in closets, etc. I usually winterize when the humidity level is low and then commission in spring before the humidity arrives. My HVAC is in operation most of the year. I would be concerned about mold during FL summer...
