Zephyr: A Free Plan for a 14 ft Racing and Cruising Sailboat
William D. Jackson's 14 ft sailboat carries 125 sq ft of sail, tops 15 mph and needs only three frames.
Zephyr is a 14 ft (4.3 m) sailboat that can race with two aboard or cruise with three. William D. Jackson gave it a 5 ft (1.5 m) beam, a convex bottom with developed surfaces and 125 sq ft of sail. The plan says it can top 15 mph. Better still, a prefab method with only three frames keeps the build simple for such a capable boat.

Fast, but simple to build
Developed surfaces are shapes that flat plywood can bend into without stretching, so the convex bottom goes together cleanly. Using only three frames keeps setup time and timber costs low. It is an elegant way to build a fast hull with very little scaffolding, which is a real blessing in a small workshop.
With 125 sq ft of sail on a 14 ft hull, Zephyr has real power. Two people can race it hard, while three can enjoy a relaxed cruise on a gentler day. That versatility is a big part of the boat's appeal for sailors who want both sport and relaxation.

Who designed it
William D. Jackson drew Zephyr for the Boat Builder's Handbook, page 98, and it was issued as Craft Print No. 287. Jackson was a mainstay of the Science and Mechanics craft print catalogue.
Before you build
- Follow the prefab sequence carefully; with only three frames, each panel must be cut accurately.
- Respect the crew limits: two for racing, three for cruising.
- Practise reefing or easing the sheets early, since 125 sq ft of sail on 14 ft is a lot of power.
