IF cosmetic only, as it probably is, I would not cut out any sound laminate - its the long roving fibres that provide strength. (It's also a lot of work.) IF I were spending big bux on topsides paint I would fill and fair, and maybe bulk up first with 'glass/mat if the divots were deep enough. Otherwise I'd leave the exterior well enough alone. Checking the knees/bulkheads for integrity, protecting from future water ingress, and adding tabbing or reinforcement inside the hull to spread out the load wouldn't hurt, it is not difficult in the larger scheme of things. and there are a few ways to do it. If anything is likely to fail its where the knee/bulkhead is tabbed to the hull/deck, or if the plywood is/was wet, the adhesion of the glass to the wood. My 33-2 had some minor cracked tabbing, and a previous boat needed a fair bit of work of this type. hardest part is the sometimes awkward location. My $.02

I don't even know if that operation is possible, and it's more than I would want to take on myself, or even pay an expert to do, if it's not really necessary because the integrity of the boat is not compromised by the dimple. Earlier in the thread Mike Hoyt said "he [Dana, the boatbuilder / marina founder] normally had to fill these dimples". I interpreted "fill" to mean more of a cosmetic fix than a full-blown repair as imagined above. That said, whenever I get around to "fixing" my boat's dimple, I will probably follow Don Casey's prescriptions in his Complete Illustrated Sailboat Maintenance Manual for laminate repair (pp. 204-217) and hull repairs (pp. 232-237) to do the job. In other words I would probably try to build up some additional fiberglass and epoxy laminate outside the dimple, instead of just filling and fairing the depression.

Just the same, would it make sense to reinforce this area of the hull if for nothing other than peace of mind? Not sure if this would be over-kill or not. Earlier in the thread mention was made of the boat builder/marina founder who used to repair this kind of problem on the C&C 30-1's
