all's well that ends well
Well, after considering the sage advice within this thin thread, I got three quotes from local folks. Amazing range from $3000 to $600. The low quote was a young couple just starting out in their business a couple years ago, a veteran who had worked in a marina shop previously to the service. After visiting the fellow's shop and seeing some of his work, and discussing his approach, I engaged him. He did a very neat repair outside and inside the bilge and took his time, taking advantage of some warmer spring days to ensure proper curing, etc. Glad I didn't tackle it myself as time goes so quickly in the launch season !!
In the water and bilge dry!~
