The top part of the trailing edge of my keel has got chewed up and needs repair so that it lifts easily again.Not sure what has caused the damage, but when lifting the keel when the boat was hanging in the slings after liftout it was evident that trailing edge initially rubs against aft nylon bush.Was wondering whether to reinforce trailing edge with a s/steel bar glassed in or will fibreglass be sufficient as in original design?

Would attach picture if I knew how! Suggestions welcomed. Nick HP P27/131
