Re: Stus-List Composite project (not CC related directly)
Thanks. If I don't have any info on it by May Id be very happy to get it from you then. I was considering plywood too. My old Bonito daggerboard is ply and it works well. I was thinking the invitation might have a more built up foil shape like a Laser which may be a little harder to make from plywood.

Re: Stus-List Composite project (not CC related directly)
Kevlar makes cutting and shaping a real pain in the butt. For a small project like that there is no reason fiberglass won't be sufficient. I would suggest foam insulation board from a home improvement store. A 2 thick 4x8 piece would be good for a couple different tries. The high density stuff is great for sanding and shaping. It usually comes in blue or pink. Don't use the white stuff that looks like it was made with a bunch of beads. 4 layers of glass is probably sufficient. Consider a stitched fiberglass product like that in the link below. http://www.fibreglast.com/product/saertex-1200-gm2-stitched-triaxial-fiberglass-2808/Stitched_Fiberglass If its too boyant then you can add lead to the lower portion.

Re: Stus-List Composite project (not CC related directly)
I can't address the original question, but to Doug's comment I also swear by 'Knytex,' which is a trade name from one manufacturer. It's biaxial with mat sewn together, without the binders that limit one to polyester resins. Once I discovered it, I never used anything else. You can lay up really strong layers fast, and for things like tabbing in new bulkheads you only need one slap. I used it to epoxy my lead keel to the stub.

Re: Stus-List Composite project (not CC related directly)
Make a profile from the inside of the dagger board well. Then I'd start with: http://www.fibreglast.com/product/Polyisocyanurate_Foam_Sheets_440/Foam for shape. You could bump up to 6 lb foam but I don't think you need the extra strength or cost. Using polyester or vinylester resin, bond a layer of fiberglass matte to get good bond to the foam. Then a couple layers of Kevlar cloth for strength. Finally, add a layer of fiberglass matte for smoothness. Fill any pits with a premium putty. Sand with 220 then wash thoroughly. Repeat the putty, sanding and washing until all imperfections are gone. This will take several tries. Finish with gelcoat sanding with 320, 600, 800 then polish with AquaBuff 2000. If you want to paint instead, prime with a high build primer, sand with 320 then 600 then spray with paint. Remember, Kevlar is more difficult to work with and to sand if you build it up too high. that's why I recommend fiberglass matte on top of it. Lastly, polyester or vinylester resin is cheaper than epoxy. I'd consider making one from marine plywood first and varnishing it. If you like it, you can use it to make a mold for the composite one.

Re: Stus-List Composite project (not CC related directly)
Brent, I'd keep it simple. From the manual it looks like the original was made from plywood with a basic foil shape. I would get some plywood, shape one out of that to fit, round the front edge, taper the trailing edge, cover it with a layer or two of fibreglass and go out and have fun. It is just an old dinghy after all.
