the water can be from any for a few places
The water on mine was coming from the dorade vents on the deck. take the covers off and look at the space between the deck and the dorade. this has to be colosed off so water can not run into the liner between deck and hull liner. not hard to do. i used some foam to close it off then epoxy to seal it up. it does not have to be structural.Look at the outside cornors of the bulkhead, find a low spot on the liner and drill a small hole on the bottom of the liner near the outside wall of the boat. water will probably come out. Small hole, just thru the inner liner.another possibibliy is the screws for the jib track. or water on the floor in the head getting to the bottom of the wall. I took the head side of the wall and cut the bottom foot off and made a starboard piece to replace it. beveled it and sealed the wood do it could not absorb water. then rand the starboard to the inside of the floor pan in the head. then c cut up the wall about 3 inches on the salon. removed all the bad material and replaced it with epoxy coated wood and epoxied it in place. then i covered the bottom 4 inches with a new teak trim molding. worked out great.YOU should also make sure the mast boot in not leaking water to the floor. not to bad a fix.
