Grey Seal

Grey Seal

Description

The Grey Seal, designed by Scottish naval architect Iain Oughtred during his 1986 residency at WoodenBoat magazine in Camden, Maine, is a robust, lapstrake plywood double-ender inspired by Danish spidsgatter fishing boats and the Swedish Folkboat, blending traditional aesthetics with modern glued-lapstrake construction for amateur builders seeking a seaworthy trailerable cruiser. Measuring 22 feet 2 inches LOA with an 18-foot-7-inch LWL, 7-foot-9½-inch beam, and 3,800-pound displacement (centerboard version; keel variant at 3,900 pounds), it draws 2 feet 3 inches board-up or 4 feet 4 inches down (3 feet 5 inches for keel), offering a D/L ratio of 264 for light cruiser/offshore racer performance and a motion comfort ratio of 19.2 that outshines 82% of peers for stability in rough water. Its gunter sloop rig provides 265 square feet of sail area (or 245 for Bermudan), enabling balanced handling up to 6 knots with a forgiving helm, while the interior accommodates two for weekending with V-berth forward, small galley, and portable head under 6 feet of headroom. Plans, available from the WoodenBoat Store for $477 (12 sheets requiring lofting), emphasize laminated oak frames and epoxy fillets for durability.

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.
