Can anyone suggest a way to stop leakage through narrow gaps between
an iron keel shoe and a bilge keel?
The gaps are relative short (a centimetre or three), and possibly the
result of long-term (thirty years) corrosion of the upper surface of
the keel shoe where it rests against the bottom of the GRP bilge keel.
The leakage water appears to travel upwards through the hollow bilge
keels and thence through the GRP hull itself to appear as sweat in one
location and a puddle in another.
The previous owner possibly had the problem some fifteen years ago
because some hard-setting cement compound appears to have been applied
to the keel-shoe interface. The compound is gradually being lost, or
becoming ineffective
I guess a fifteen-year solution would suit me, the question is - how
to go about it.
=============================================

I assume the iron shoes are secured with bolts? If so the solution is
just like fixing leaky keel bolts. Haul the boat, drop the shoes,
clean up the shoe tops (remove the rust), replace the bolts if needed,
re-bed the shoes with something like 3m5200, and put it all back
together.
