Larger O'days - Mast Collar Leak

[Clutch Cargo]

If there is any benefit to all of the rain we've been having here in Maine is that you certainly know where your boat is leaking. In my case, the mast collar has always leaked a little, but in the last week (since she has been in the water), it is more pronounced. I assume it is coming from under the mast collar. I think it must've been done at some point given the nylock nuts and evidence of sealant. Has anyone ever removed one of these?

Before you ask, the mast slots have been sealed.

Yes, I have

The partner plate was sealed to the deck with a sealant that resembled 4200. When I resealed it, I THORUOUGHLY cleaned the deck and the bottom of the partner plate, and put a nice thick bead of butyl tape between the deck and the plate.

Thanks very much for the insight. I assume "partner plate" is the correct term for these things; and it does make sense. A bit of a wooden boat throwback.
