On most boats I've been on, the coins are encapsulated in epoxy..so no electrolysis concerns, and Charon isn't bothered by the epoxy.

I have to think there's some sort of raised center that the mast fits over or around, which keeps it from moving.

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.

If you look at the line drawings and photos of the N-28 MKII on capitalyachts.info it appears that there is a heavy wood post on the corner of the bulkhead, at the door to the head. This is the compression post that transfers the mast compression load to the hull. On models with an aft head this compression post is located in the middle of the drop-leaf table. On the mast step there is an extrusion inside that keeps the mast from moving laterally when being stepped; but once the shrouds are tensioned the mast is under compression load and would not move laterally even if you tried to push it off the base.

Yep, I have seen that wooden post by the head. OK, now I know what I'm looking at.

I guess there's no way to get the mast down at the slip, as there's just not enough distance in any direction to ease it down. I guess you'd have to take her into the lift slip and drop it there.

It is likely easiest to unstep your mast by getting your boat near a crane of some kind. The height of the crane need only be a few feet above the spreaders.
Our club has a human operated crane on the dock with purchase for doing just this while the boat is in the water. Calm days are best for this obviously.
You should not have to haul the boat for this procedure.
