In 1901, Thomas Fleming Day, who founded The Rudder a decade earlier, conceived a boat that would bring ocean voyaging to the common man. Simple enough to be built by amateurs, small enough to be singlehanded, and big enough for long passages, the Sea Bird yawl still beckons those with a sense of adventure.She was originally a centerboarder, but Day soon added a deep keel for ocean passages, including an Atlantic crossing he made in 1911. With The Rudder’s publicity, plans, and instructions, the design soon caught hold. Hundreds have been built. Day’s vision turned out to be unusually lovely for a hard-chined hull, in plans formalized by C.D. Mower and Larry Huntington. Boats of this type have cross-sectional shape consisting of nearly straight lines rather than the svelte curves of racing craft. Sea Bird’s sweeping chine curve rises high forward and aft and just kisses the waterline amidships. The shape is complemented by her gaff-headed yawl rig. In 1981 WoodenBoat, working with Mystic Seaport, had the plans redrawn by Dave Dillion (see WB No. 43), and the seven-sheet set of plans, which includes the deep-keel option, is still available through The WoodenBoat Store.

At 25’ 7 1⁄2” overall, the centerboard version of the Sea Bird can—with effort—take to the water each spring from a launching ramp, with her 1,300 lbs of ballast added later.
