Hi, I don’t have any experience with the kind of work
you need done but when I was looking to get a full bottom job on our boat
last year I called a lot of places and can suggest a few if you wanna look into them:
Silver cloud marina in Forked river, NJ
Barron’s boatyard in City Island, NY
in Huntington, NY
West Shore Marina in Huntington, NY
I had the work
done at West Shore, the marina is not full service
but there’s a guy who does a lot of hull
work, pm me if you want his name and contact.
I would start calling places and ask what kind of work they do, visiting some of those places to see their work in action would be even better as you can assess their work.
Another thing that you may or may not be doing is asking various surveyors, local people know where they do good work and can refer you.
You can also ask other Beneteau
owners for recommendations.
