My experience has been the opposite. I purchased a wooden hull
sailboat that was in the water when we bought her. The bilge
never ran. In October, I hauled the boat to clean & paint
. I did some minor caulking, and re-painted the hull. Because of bad weather
, she sat on the hard
for six months before I could put her back. After 6 hours in the sling and using 2 sump pumps with 2 bilges running, I had to pull her out. The planking had shrunken so much while she was out, I am now re-packing the oakum and re-caulking the entire hull. Hopefully, repainting and putting her back in the water for the winter! I lost
the summer, now looking forward to next season. Next time, I'll try to keep her out no longer than a couple of weeks.
