Jim Campbell was recommended by the owner of a boat we were interested in (owner changed his mind and kept her). He used Jim when he bought that boat. We have not yet bought our boat, but Hubby has had several occasions to communicate with him and he has been very helpful and has given us good advice, so far for free. He will be our first choice surveyor.
As to FL boat brokers, we had a boat sold out from under us (we had made a formal offer & put down a deposit). The boat sold for $2K less than what we offered. So BEWARE!
