When a customer came looking for a replacement rudder for a Cheetah 30, the boat's designer Bob Ames was kind enough to send the cad file of the rudder design.
This one is built over a balsa core rather than the original spec. foam, and as a one-off product with the laminate wrapping around the leading edge, rather than the split-molded original, it should be a bit stronger than stock. Lighter too! We've supplied these now for most of the Cheetah's built.
