The simple rule is NEVER use screws in FG. They will always fail. Fastener
load must be distributed with some kind of backing.

A few weeks ago I posted about fixing a seat on my sailboat that was loose.
Today I removed all the screws and pulled the seat out.
The screws are held only by the fiberglass; I thought there would be some
wood, but there isn't.
I plan on using bigger screws in the existing holes and adding a few new
ones.
My only real problem is what to do about one screw hole that I tried to
fix
last year, but just wound up making way too big for any screw. Can I
stick
a plastic wall anchor in it, or maybe a toggle bolt; or am I best off just
abandoning it?
