I'm working on a wood framed, nylon skinned Sea Pup. The Yost coamings are designed for PVC skinning and sandwich the skin between a frame mounted base ring and the exterior portion of the coaming.

I'd appreciate a little advice on the best way to mate the coaming to the skin.

Options are:
1- Follow the PVC directions and sandwich the nylon between base and coaming (Screw through the fabric to clamp the Exterior coaming to the base plate)?
2- Delete the base ring and sew the nylon to the wood of the coaming?
3- combine the two, leave the base ring there, route the nylon over the base, sew to the coaming?
4- some better idea?

The coaming I'm building is bent strips. They are bent and clamped to dry, but not yet glued (see link). The vertical wall of the coaming is 3 strips totaling about 0.6" thick, and the lip is another 0.4". If I go with either of the sewed options I can delete a ring and thin the wall to 0.4".

Any thoughts?
