In heavy winds last Sunday (7/22) my rudder snaped at the water line - the broken off part disappeared as my C&C 24 was blown in circles until I got the sails down. A replacment was quoted at $2900. The construction was fiberglasss mats over two sandwiched mahogany planks. I am looking for advice on rebuilding it. Would marine grade plywood be stronger? I thought I would cut the general shape out of mahogany or plywood sandwiched together and then over lay it with fiberblass mats. Any suggestions?
