Kenny Kreutzfeld began working on vintage wood boats when he was a kid. And now more than 50 years later he’s still at it, operating K & M Restorations in Marblehead. From turn-of-the-century boats to more “modern” Chris Crafts and Lymans from the 1950s and 1960s, he tears them apart and puts them back together, troubleshooting and eliminating the number one problem with wooden boats: leaks. And some of the industrial equipment he uses is more than a century old. Let’s visit his workshop and talk about old wood boats.
