When we put Kewalo away last fall, we set the shrink wrap up thinking we would be away for a minimum 2 years. We had extra vents installed, and a large zippered door. Our intent was to open the zippered door halfway, install some screening, and leave it open for the summer. The screening was to prevent birds etc. from having an easy access/exitway.
We left all the opening portlights
open, the hatches open, and installed a vented door in the companionway
. Again, all openings were screened.
Over the fall/winter/spring, we monitored progress in the boat, and there was some water
in the bilge
from running down the mast
, which is still up. When I say some water, very, very little. We had also left moisture absorbers all over the boat which can be had at the dollar store for very little. They work great!
In retrospect, a zippered door at each end of the boat would work better in creating a breeze inside of the plastic, and the boat.
It is very humid in the Windsor Ontario
area, and as of two days ago there is no mold
, mildew, smell or anything. I am confident that with occasional inspections and changing out of the moisture absorbers and any water in the bilge
..and she would be fine.
We decided to sell her off, and she will be on her way to her new home in CT at the end of the month, so...that's all I can tell you. Set up this way, she has weathered...the weather
, very well.
If you have power available for a good rate, installing a dehumidifier would certainly prove beneficial as well. Set it up to continually drain down your sink, in the warm weather
Good luck with your decision!
