I have put my boat up on the hard for a year now and will leave it for another two years. After one year I visited my boat to see how it was holding up. It was great, no mold
, no water in the bilge
. It looked the same as I day I left it. It is on the hard in Virginia, lots of heat, rain and humidity. The boat is not covered. Here is how it was prepared for for long term storage
as it related to moisture and mold.
1. Batteries were removed
2. Lowest part of the bilge had a hole installed with a fitting and plug
3. The plug was removed and placed in the galley
sink for storage
powered rechargeable fans installed in two hatches 1 intake 1 exhaust
5. Placed a 12v fan in rear stateroom hooked to a solar panel (runs during the day)
6. opened all drawers and cupboards
7. Stacked all cushions
so as to have air circulation around them.
8. removed all floor boards (placed them cross ways to allow air flow)
The advantage of the hole in the bilges, eliminates the need to rely on batteries in the event water does enter the boat for some unknown reason.
