Shroud Fittings and wet bunks
- Unlike boats that have a lot of wires for standing rigging, with our
low drag rig we can't just back one off and fix it while the others keep
the mast up.
It's that "all your eggs in one basket" thing.
It's ok to put all your eggs in one basket, but you have to take real
good care of
that one basket!
While my boat is on the hard with the mast down (and the weather turned

Actually both of them.
So yesterday, in the 80 degree last day of February, I went up over to

Cure that I had run in there).
I finally got a chance to examine the deck construction in that area.

The good news is - no wood - just high density core material.
I doubt there will ever be a problem with wet core there.

I've become disenchanted with silicone.

Second it is hard to make a good gasket with it. It has to cure before

about letting it

and can have voids in the gasket.
The oils in silicone soak into the gelcoat and glass and are impossible
short of grinding off the contaminated materials.
I'm going to seal it back up properly using really high quality butyl

MaineSail's technique is to countersink bolt holes (and the slot too) so
that the deck
edges are lightly chamfered - angled - so that the tape will be
compressed down into
the opening creating a complete seal. I like the dry bunk idea so much
that I'm going
to follow his plan. Will let you know how it turns out (someday), but I
it will not leak any more.
Now the problem is, if you have a similar leak, you can't just lift the
fitting and seal
under it without dropping the mast. But you may be able to rig a
temporary stay using
the main halyard.
And normally we would not recommend sealing the inside-the-cabin part -
that would just
trap any water that did leak in and cause potential wet core problems.
But is that really a possible problem with this setup?
