Neil -- the right stuff that stays flexible to keep water out without being brittle really wouldn't transfer stresses.

() I do agree that the key is to keep the plate from moving around the fiberglass. Because the backstay gets a bunch of variable shock loads from wind, seaway, and sail loadings that are imposed on the stay, you really have a complex structure that really functions like an stayed antenna tower in an earthquake zone :^)

- Chainplate screwup.
- what kind of bolts are you looking for?
- well, how about this?
- Isn't there a backing plate, Dan?
- I seem to recall warnings about undersized clevis pins
- The issue with the chainplate is not just the shear strenght of the bolts, Charlie
- Bolt sizing
- The induced friction from compressing the chain plate against RFP would help -- but ultimately, I'm not how much
- You do NOT want to torque bolts too hard in FRP. You can crush the fiberglass structure and weaken the area.

- Dan, do you have the old bolts with you?
- Update, photos and some info. after responses.
- At the very least, put a light load on the chain plate...
