I would like to see some design ideas for a composite shoe/shaft option for our boats. I know there is a great deal of strength in resin and fabric but how well do you think it would hold up to occational grounding even if only on sand and mud? Maybe if the shoe was beefed up by increasing the height thickness such that the point where the shaft inserts into the shoe is 5-6 inches above the 'heel' of the keel for lack of the proper term. Would all of this lead to a reshaped rudder? Maybe bring back the constellation rudder Ebb was working on circa 2003?
