You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

And I thought you guys understood boats.

Here's the thing about leaks - if you want them to leak, they won't. So any deck leaks, any mast step leaks should be incorporated into your water collection system. Ergo, no longer a problem.

I have noticed that deck scuppers and cockpit drains can be completely negated by a single little leaf, able to hold back many gallons of water.

You have seen it too, I am sure.

So forget fancy mast boots; don't even consider tubes of caulk, or any other anti-leak schemes. Place a leaf above any suspected source of leak or place a hose that will shunt any deck leak into your water tank. The leak will vanish.

If that fails, always remember, without deck leaks, how would you know where to store your buckets?

I am 100% sure that you can design it not to leak. There have been bigger engineering challenges in the history of man. It is just the fact that there is no simple and economical solution that causes manufacturers to keep making leaky boats. For instance, at great expense, the spar could be custom manufactured with a welded in aluminum dam inside at the lowest halyard exit, or an epoxy dam or the like. For outside leaks, the spar could have a welded on skirt with a matching labyrinth seal profile integral to the deck.

It doesn't have to leak, that's the point.

The question is how bad does the leak bother you? $5000 bad?

Perhaps a more well designed mast boot is in order. If it was sealed at the top with a hose clamp and there was a steel ring bolted to the deck, a UV resistant boot would be easy to design. It's just the extra bother and expense that stops these designs from being realized.


Along with the fact that my mast is deck stepped.

Its funny, I had a conversation about this subject with Dudley Dix last week. I had mentioned my idea of creating a moment connection at the deck so that I had a deck stepped mast that behaved like a keel stepped mast. He told me that he had used the balloon and epoxy trick very successfully on one of his boats. While that does not solve the issue of being able to jetison a lost mast at sea before it holed the boat, it at least stopped the water coming down the mast.

To avoid the issue that SD raised, if foam is used, it needs to be a closed cell foam so that it does not tap moisture against the mast. (Not all spray foams are open cell.)

I have watched for leaks around my mast boot, even when I try hosing it at full power, and it generally does not leak. I typically loosen the clamp and boot and recaulk it with silicone every couple years and as a result leaking at the boot has not been a problem.

The MC is wood so fresh water leaks are a concern. This is how the man who built the boat dealt with water in the mast. He drilled a hole 8” above the bottom of the mast and inserted a PVC fitting. Then plugged below that with foam. Water is stopped by the foam, goes out the drain and is collected in a jug. This does not solve any mast boot leaks but I have emptied that jug many times so it is keeping some of the water out of the bilge. Dan S/V Marian Claire
