1/4" ply covered in formica. Itll take a nice fair curve and the formica will act as the release. Coat of wax wont hurt though...

That's what I use also, formica. The big box stores sometimes sells it off cheaper if it has cracks and broken corners. I always look for the discounted stuff. Melamine board works well too for molds but the formica will form well to the curves.

Thanks for the pointers. I went to home depot in search of Formica, turns out you can only get in online. I ended up with 4x8sheet of hardboard for $14. Not familiar with it but looks like it will work, one side has a nice smooth glossy finish. I ripped some 6" strips of hardboard and glued it to luan for some rigidity, also added 5 coats of wax. Hope they pop!! Screwed one in place and it followed the shape really well. Look forward to trying them out need some dry weather.
One question, has anyone kept the sheer on the cap while they core it? Before we took the cap off we tried support the cap to keep the flex in it to match the shear. Is this necessary or will the cap be flexible enough after coring it to bend it back into shape. Its not a great shot but shows it a bit. This is pretty far aft. Transom is just out of the frame on the left side.

Few updates...started messing with some expoxy (transom was done in epoxy- this is our seam from poly to epoxy). It was a tough learning curve but wetting out the 1708 first makes all the difference.
Finished raising the stringers and tying into transom. Cleaned up the bilge, patched/putty imperfections, added a couple layers of 1708 to the keel and one layer to cover everything. Much better now some of the old roven was looking pretty aged/dry. Finished coring the hull sides to the transom. Divinycell all the way aft for thruhulls. Plan is to keep the balsa completely sealed.

I'm confused. Was there a user name change I'm not aware of?
