Plywood-epoxy F18's are illegal unless they are made of balsa.

D.3.1 MATERIALS
(a) The hull shells shall be built from polyester or vinylester resin, glass
fibres, polyester gelcoat, a core of PVC, balsa or felt, the combination of wood-epoxy, injected plastic, which shall not be altered other than locally for fittings, and passage of equipment and normal reinforcement. Epoxy glue is permitted for joining components. Every material that is not expressly permitted is prohibited.

Looks like wood-epoxy is allowed.

Wow, I have read that rule wrong for years. I thought it was trying to say that only a "wood" epoxy could be used. I even asked for a clarification once about what epoxy would count as "wood" epoxy. Yet another example of poorly worded rules.
