Have a Grady white marlin 28 ft located in bayville area of New Jersey looking for a reasonable fiberglass guy to possibly do a repair or transom replacement
Get a quote from Ocean Gate Yacht Basin Marina at 65 Bayview Ave, Use that as a benchmark to compare other estimates. They have a decent repair shop but like most boat related services, they can be expensive.
The major issue I see is that without seeing the actual boat as well as not being able to determine the scope of the repair without possibly doing some 'digging' , they may not be willing to make a firm estimate.
