I agree, drill a small hole, but I wouldn’t seal it up.I think I would drill a hole in the bottom mast cap , drain the mast and seal the hole with silicon or 3m 4300.
I would like to know how the water entered the mast in the first place. You could probably do an air test after the mast is drained to locate the problem.
Rinse the inside of the mast with fresh water afterwardsThanks for all the responses. I drilled the hole and will leave it open so it can drain in the future. My only concern is the mast will eventually corrode from all the saltwater.
Skip the sealant...L&VW, the idea is to drain the mast after each sail, not let the mast sit there full of water.
If anyone finds a sealant that is proven to work when sailing in wind and waves for more than a sail or three, pls let us know.
Skip the sealant...
Drill two holes in the bottom cap, loop a cable-tie for a grip, and remove the cap for each rinse...
