Leak @ keelson/keel join

[John Wragg]

Rosanna has been out of the water 5yrs plus now,i have totally restored her from the keelson up and have recently re-caulked and painted/anti-fouled hull ready for launch.Spillage on water tanks test left water in bilge that found its way out :eek: ! the leak is between keelson & keel(not keelson and garboard),she had new keelbolts fitted by the yard where i bought her & they had bedded the keel back using a mineral felt & a sealing compound of sorts which appears to have failed.Has anyone had the same experiance and if so found a remedy?

If you could call the yard and ask them what they used exactly, it would help a lot with the diagnosis :)

If the oak timber and the stopwater have not swelled (stopwater should be within a day but the oak might take a week or more) then it should be expected after so long dry. [edit] If I assume that what you call the keel is the ballast and what you call the keelson I would call the ballast keel, then the stopwater is not involved, but still water can leak around the bolts and will find a way out. Swelling will happen (in all directions!) when wet and the whole assembly should tighten up. We hope... but there is reason to expect it if the job is well done.

Not to be irritating, but:
The keel is a wooden timber that the stem, sternpost, and frames are attached to. The ballast keel is a new-fangled metal casting added to provide stability in lieu of honest cargo or ballast that can be shovelled overboard to make way for honest cargo.
The keelson is a timber used exclusively (I think) in conventional sawn-frame construction. It runs parallel to the keel, but above the frames. Honestly I can't explain the structural logic...seo

Thanks TimothyB,Thad & Seo,i have been thinking of just letting the saltwater do its thing and see if it does take up,then if after a couple of months there is still too much ingress i will know that the seam definately needs attention,(of course allowing also for the plank seams), thanks guys it helps to air your thoughts and hear another take on things smile.gif
