Do you think I can add a new mast bottom plate without dropping the mast? Seems like it would be pretty straightforward. Remove the old plate?

Thanks

Don't see how it's possible. The plate has to go under the tablernacle (correct term??) To do that you have to remove the mast.

If you have a mast raising crane at your disposal you could do it. Just release the stays enough for the mast to come up of the deck by about 4". Then remove the old tabernacle, place the new plate and then replace the old tabernacle. I found when I did this that I had to drill a few new holes in order for all of the existing holes to line up.

The plate is held to the boat with 4 large wood screws. Impossible to screw them in and caulk without removing mast.

Raise mast 4" and then use a right angle attachment on the screws!.

Ray;

I added a mast plate three years ago, and I had to fill and re-drill the holes for the wood screws into the deck/compression post because they were a little soft. I replaced the screws with 1/2" longer ones to insure a good bite with the added thickness of the new plate. I also had to drill two additional holes in the SS mast plate itself, because the holes did not line up with my tabernacle and deck. I also bedded the mast plate down on the deck with Marine Tex to make sure the plate/tabernacle/mast had a good, flat surface to rest on and screwed it in place. After the Marine Tex had cured, I removed it and sealed it down with 4200 to the deck and replaced the screws.

Oh, ya, I removed the mast to do it!

I've removed my mast base on my S2 with the mast up. I loosened all of the stays, removed the two pins, and set the mast so the bottom of it was just aft of the plate. If you do it this way, you might want to tie the bottom of the mast to something so it doesn't get bumped and the bottom slip out.

I did this on a C22. You want the mast down. Technically possible with the mast up? Sure. Good idea? No.

We added the stainless mast plate today just before raising the mast, which was down while the boat was being repaired. 4 machine screws, 2 forward and 2 aft, none into the compression post, and all 4 lined up perfectly. The 2 forward screws are under the mast when raised, and appear below in the head area just forward of the bulkhead. The 2 aft screws appear in the main cabin. After adding the plate, I had to leave off the lock washers because the screws were not long enough. All 4 screws are covered by cap nuts below.

Thanks a lot for the advice and the heads up on the differences. It always amazes me how many "straightforward" things on these boats are auctually quite specific in design on each particular boat.

That is one reason I enjoy the images of the boat details.

We each have a unique Catalina!
