Because I'm keeping the mast

marks on the fiberglass
Have thought about what problems painting them might create. Awlgrip has a s.s. priming procedure. Haven't really decided 100% on this yet.
I moved the chainplates outboard
from the original thru-deck plates which are impossible to seal. Went from 1 1/2" to 2" x 1/4." The common bulkhead rot
in these boats is caused by these thru-deck leakers. Once water
gets into the end grain of plywood
, trapped between glass it's all over- a bad design idea from the start. Was a major job to replace one of the bulkheads which was totally rotted.
All of my backing plates are hidden inside lockers so there was no problem with clearance/appearance. Was therefore able to use the old ones for backing. Just thought they were more substantial than washers and they were there. Drilled them right along with the new chainplates. The hardest part of the whole job was filing the holes in the new plates for the 3/8" carriage bolts with a hand file...whew. My old boat is 1/2"-5/8" thick even up at the gunwales, plus, where I drilled through was in the glass buildup for the bulkheads, so it was easy to do. With a modern thinner hull doing it would probably require some additional glass inboard and you'd have to be careful not to distort the sides with the s.s.
