Thanks Daniel, yes the same problem here.. old Sicaflex layer upon layer...I guess that since the water will eventualy come down the inside of the mast.. the issue is not be able to drain it properly and lead it into the bilge.

Apologise for the confusion: on my own FP i dont have this issue .. it is regarding a monohull that was offered to me. Thanks

Check the owners sites for solutions.
Ok.. thanks... Will have to work on a simple and efficient draining system.

Re: Water at mast base, through deck construction

Oh ok, do you know what a inner plastic dam looks like,,, water in the bilge from the mast is a isue from the past this days ,,, the only problem is to install a inner dam you need to unstep the mast.. Cheers.

You must be sure the material under the mast base is dry and them I would countersink the holes and apply a liberal layer of butyl caulk before reassembling. You MUST stop any water from coming thru.

Ok, thanks Ed, i wasnt planning on removing the mast.. I will first check the other alternatives.

Re: Water at mast base, through deck construction

A deck stepped mast doesn't interest me, but in 2014 on this forum I started a bunch of raving nutters decrying a perfect solution to fitting a keel stepped mast, which cannot leak, is permanently part of down below and is easily removed. I have lived with my mast for twenty or so years and do not know what water down below, is!--- in any weather and conditions.
