Sorry for the late reply.
I am with Bruce when he writes about bedding with epoxy putty
and then taping with glass weave. Orient fibers +/- 45 degrees.
Scroll down to the middle of this page for some photos of
interior parts bedded to hulls:

Later I learned a neat trick from Danish designer Lars Oudrup:
Fixate parts to be bonded using heat glue. You don't need much
since it is only there to keep things in position while you
apply the epoxy putty and while it cures.
