I've update my Blog with the latest progress. Grinding out the transom from the inside is taking longer than expected.

Question - The transom chainplates and rudder are strengthened with 1/2" plywood glassed over the balsa. When others did a transom rebuild, what did you use to replace the plywood? I was thinking it may be better to glass in a piece of similar sized G10 both for strength and guaranteed no moisture absorption.
