Arctic Tern Sloop

Description

The Arctic Tern is a versatile, double-ended open sailboat designed by Scottish naval architect Iain Oughtred, known for his elegant wooden boats inspired by traditional Shetland yoals (Norse-influenced fishing workboats). First introduced in the late 1980s as a scaled-down version of Oughtred's larger Ness Yawl, it evolved into a standalone design emphasizing camp-cruising, day sailing, and long-distance rowing or sailing adventures. Built primarily from glued-lapstrake plywood for lightweight strength and ease of home construction, it's intended for solo, or two-person use, with enough open cockpit space for comfort and flotation compartments for gear storage during weeklong trips. The boat is rigged as a gunter sloop (with options for lug or yawl rigs), offering a balance of speed, seaworthiness, and simplicity—no outboard motor is typically needed, though modifications exist.

Custom sail calculations are not possible for this boat as no I, J, P and E dimensions are available.

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.
