Hello Crusty
I sorry I can't help with a local surveyor. But if I was to buy another boat I would also get a builder (shipwright) to also inspect a boat. My last boat passed survey with flying colours. (that kept the insurance company happy). But 4 months after I brought it, a rust spot appeared on the outside of the hull where the anchor locker was. The photo shows what I had to do. Fortunately I can weld and had somewhere free to store the boat. But the cranes and trucks involved weren't free. Beside the 2 meters at the pointy end, I also replaced another 5 sections of the hull. Fibreglass and wooden boats can also be full of $urprises. A builder may be able to give you information that you can use to bargain the price down (if you still go ahead with the purchase) so you will recoup his fee and if he finds nothing then you will have peace of mind.
Fortunately my story has a happy ending. I also cut a bow thruster tunnel in while I was at it.
