Plywood 12-1/2
Description
The Plywood 12-1/2 is ac design by Phil Bolger in homage to the Herreshoff 12-1/2, part of his portfolio of simple, practical boats tailored for amateur builders. Unlike the Cartopper, which is smaller and car-toppable, the Plywood 12-1/2 (also referred to as the "12-1/2" or "Plywood 12-1/2") is a slightly larger, lightweight plywood sailboat designed for day sailing, rowing, or motoring in protected waters. It’s not explicitly part of the "Instant Boats" series but shares Bolger’s philosophy of minimalist, functional designs using stitch-and-glue or taped-seam plywood construction. The boat is known for its ease of construction, affordability, and versatility, making it a favorite among DIY boatbuilders.
