How to Address Vintage Boat Structural Issues

Vintage Boat Preservation How-To

No matter how diligent we might be, at least some part of the wood in your boat will rot at some time. Fabricating a new bottom typically means replacing both the inner skin and external planks. Working on your boat’s bottom means first flipping her. Just dropping your inboard engine onto its mounts and bolting it down does not align it with the drive line.

Preservation often means releasing the keel, gripe, stem, planking and frames.

These are but some of the topics this section covers.

Sadly, Don Danenberg, North America’s foremost wooden boat restorer, has retired. Happily, however he is still writing and has just published what I consider is the seminal article on repairing antique and classic wooden boats’ bottom frames. The piece, entitled simply, “Bottom Frame Repair,” appears in the new issue of Classic Boating, November / December 2021, and is a must read for novices and experts alike (click here to read the article).
