Thanks for this!!!!
I have the exact problem in the exact spot. Now I know it is a problem I should worry about and more importantly I now have the solution.
This is awesome!
The only thing better is not having the problem in the first place.
Mine is a 1975 H16.
Not interested in racing. Just having fun and teach my kids to sail. I only just bought her last fall for a wopping $350 with trailer. Now a couple hundred more dollars of parts and trailer re-build and a buch of elbow grease I think I almost haver her ready.
Except now I have to fix that soft spot. Sure hope my local West Marine store has this stuff in stock!
