Arrowhead 21
Description
The Arrowhead 21 is a classic wooden sloop sailboat designed by renowned naval architect Philip L. Rhodes in the mid-1940s. It's a one-design keelboat known for its graceful lines, seaworthiness, and suitability for both day sailing and short coastal cruises. Approximately 42 examples were built at Cataumet Marina in Massachusetts by boatbuilder T. Barry Kingman during the post-World War II era, making it a rare and collectible vintage vessel today. The design emphasizes simplicity, performance, and craftsmanship, with a focus on plywood or traditional wooden construction for amateur or professional builders. It was featured in the 1950 Popular Mechanics article "23 Boats You Can Build," highlighting its accessibility for home builders at the time.

Disclaimer. Boats are not all the same -- even when produced in the same factory of the same model. Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them. You should take the same precautions, especially when the data is not from Sailrite.
