[C38] Chainplate replacement

[Max Soto]

Sorry Phil,
it was my front lower on starboard, the one that goes on the closet The
easiest to remove and inspect on the whole boat!!!).
 I wasn't even inspecting it..I just removed it to seal it and the two
bolts. while cleaning it, I found lots of cracks along the weld, because the
bolt had loosen up.
I'm going to replace the whole assembly...

The ones that you mentioned will have to be replaced. They had lots of
corrosion and some cracks on the plate visible from the inside, but the
bolts are ok.... I'm going one chainplate at a time!

After replacing the front on starboard, I'll go for the one at the head and
then the ones for the afts lowers...
Any recommendation?????

I don't even want to get it started with the shrouds since they are simple
and straight ss plates...
Regards,

Max
