thanks fellas,
issues with ply noted, I have heaps of ply at my disposal hence the question, To elaborate on what i was thinking, i'm finishing off a boat I started years ago, a oneocean Cirrus hybrid. Being a hybrid it has relatively sharp angles at hull/deck join. aS well the cirrus has a very shapely bow for a S&G.

i don't have ready access to WRC or paulownia but have lots of ply so my plan was to shape the upswept curve with a bandsaw (3/4 20mm wide) and run a heap of kerfs along the length of the clamp to allow it to conform to the entry exit angles without placing any load on the sides as I've already stripped the deck and glassed the hull. Not worried about strength just somewhere to plonk some glue. Good point about planing difficulty, might be a job for my trusty 4"disc sander

however, i do have some left over WRC strips that I could laminate together as another option.

one idea often leads to another, Cheers
