Earl,
Chainplates are the easy part. ;-)
Simply _narrow_ the core at the deckedge, and wrap glass over a tube of the
correct size for the pin you want to attach the shrouds with. Then trim out
the middle by the width of the toggle, position toggle and slide in pin from
the end. A glass chainplate totally integral with the hull.
You can do the same at the bow, since I'm assuming you will have a rubber or
balsa "bounce bow" in front of a structural flat. Just do the headstay on the
flat.
Any questions, email me and I'll draw some piccies for you ;-)
