Rudder blades and centreboards are either solid timber, laminated timber strips or ply. Ply is the easiest material if you intend to make them yourself. It must be marine grade and should be anti-fracture ply. This is ply where the grain direction of the veneers are not at right angles to each other.
I have in the past made a centreboard in standard marine ply, but I made it thinner than the case and then sheathed it in two layers of glass cloth and epoxy – never broke.
