Leaks
« on: July 14, 2022, 02:52:03 PM »
A long message for you all about leaks in the tank.

White Squall, # 122 has been very dry.  Normally we have a cup or two of water in the tank and none on the cabin floor.  Suddenly we're seeing several inches of water both in the tanks and on the floor of the cabin.  During last night's race, in light air (never had the rail in the water), we ended up with 2 or 3 inches on the cabin floor and about the same amount in the tanks.  We keep the boat on a shore station.  Last week, I let her sit at the mooring last week for an entire day.  No water.  It seems this only happens when we're underway. 

On further investigation I noticed that the seam between the inside of the hull and the "pan" that makes the tanks has failed.  This is on the Stbd. side more or less under the cockpit.  As the boat flexes, there's a gap that allows water in the tank to migrate into the cabin and vice-versa.  I don't know how much of that seam has failed.  And before I begin a repair I will need to jam some wedges in there to really open it up.  What is the suggestion for a repair?  Thickened epoxy or 5200?

Based on other posts, I suspect the water is entering the tanks from a gap around the centerboard trunk.  I've installed a new gasket on the bottom of the keep top plate.  I didn't see any water coming in there while we were underway last night.  Is there any other seal around the centerboard?

I'm now thinking that the water is coming in on the sides of the trunk, into the tank.  We've had repairs done here in the past.  Right now we can only access the tank through the 6" inspection ports located on either side of the trunk.  It would seem the first step is to make larger holes and install rectangular, maybe 11 x 14" locking hatches there to enable us to actually get in there.  I'm also thinking about installing round inspection ports on the more or less vertical surfaces on either side of the trunk just forward of the keel lifting post.  Openings there might enable us to look at the aft section of the joint around the trunk.  We have dropped the keel and made some repairs from the inside of the trunk.

Please let me know your opinions and experience before I start tearing into this with my Saw-zall.

Thanks

Don

Don, you should call Craig and Elkhorn and consult with him on the repair.
