Rainwater Leaks: Part 3 (Mast Boot)
After all the rain we had while Hurricane Joaquin passed by us and the discovery that we had a major leak in the mast boot area, I disassembled the interior trim ring from the ceiling. The trim ring still contained rainwater a day after the rain stopped. Water dripped from a couple of bolts that hold the exterior deck collar in place, even though it may have been because they were immersed in the water that remained in the trim ring.
|The exterior mast boot area where rainwater leaks are originating. The deck collar |
is the brown metal ring where the turning blocks (pulleys) are mounted.
As I was installing the black LifeCalk around the mast boot area and squeezing
the tube to force the sealant through the nozzle, the bottom of the tube
ruptured and I lost half a tube of black LifeCalk on the boat's white deck.
|This photo shows light coming down from the main sail track (in the center of |
the photograph). Silicone was previously used in this area as a sealant--it
was cracked from age. I think this was the major source
of the rainwater leakage.
|I replaced all the old silicone in the bottom of the main sail track with |
black LifeCalk using a cable tie as a sort of trowel.
|This photo shows how there is now no more light coming through the main |
sail track--hopefully no water will come through either.
After a recent rainstorm, it was clear that the leak had been fixed by replacing the 30-year old sealant!
