Some more priming work done on Christmas day... I rolled her out into the driveway for more room to work, the weather was fair, sunny and about 65 degrees today.
All of the primer is Interlux Pre Kote, but I tinted a quart of it grey for the decks where the nonskid will go later. I decided to pre-mask all the areas where the chain-plate eye bolts and life-line stanchions will go. I will prime those areas with white and topcoat with gloss white Brightsides. That way when they are eventually bedded they will have a smooth glossy surface to sit on rather than bedding into rough nonskid.
No real magic tricks to the masking, I just used a plastic cup that was slightly larger than the new-style chainplate eye-bolt bases will be. I made a cardboard template so I could fold one edge where the stays are close to the cabin top. On the Stanchion bases I just marked the base plate and then makes out a little farther, maybe 1/4" around.
