The only way to properly repair a soft core is to cut out the bad section and replace the rotted wood with new wood and then add the fiberglass over and under it like the original construction.

Unfortunately, this is not a problem that short-cuts like CPES or injected glues will fix properly. It will just be a matter of time before the rotting process continues and in the end you'll end up with a bigger problem to fix than you have now.

This is not just me talking. This subject has come up countless times on the Grand Banks owners forum, and the consensus of the extremely experienced folks there, some of them ex-yard owners and professional shipwrights, who have dealt with this problem on both wood and glass GBs is that you either do it right or you get to do it over and over until you do do it right.

If you are not going to keep the boat all that long, the best approach may simply be to ignore it and let the next owner deal with it, although when you sell the boat you may have to reduce the price sufficiently to have the problem taken care of as part of the sales agreement. Or get it fixed at your own expense to avoid dropping the price.

But if you anticipate keeping the boat for a bunch of years, the only real solution is to bite the bullet and do the repair properly or have it done properly.
