[Public-List] Bulkhead Repair

[Jonathan Bresler]

John,

Thank goodness, I have not had to do this.   Have enough other items.
Fortunately, none structural.

Suggest considering using a jigsaw and oscillating tool to remove a section
of the bulkhead by cutting along the underside of the deck, the inside of
the hull,
and vertically inboard of the rot.  Use the removed piece as a template for
a
replacement piece of either plywood or G10.  Fiberglass that piece back
into place.

Pick up the chainplate bolt locations from the piece removed, as well.
Check chainplate
bolts to make sure that they are large enough and shoulder bolts, not fully
threaded.
Constance has 5/16" shoulder bolts of 316 stainless steel.

The chainplate backing plates are full length 1-1/4" wide, 3/16" thick 316
stainless steel
purchased as bar stock from https://www.onlinemetals.com/ and cut to length
then
drilled using a drill press borrowed from another Alberg 30 owner (Thank
you!) using
the existing chainplates as a drilling template.

Couple writeups that helped me when I replaced the bolts in Constance
