Grampian 30 Std Rig

Description

The Grampian 30, designed by Scottish naval architect Alex McGruer and produced by Grampian Marine in Oakville, Ontario, from 1969 to 1977, ranks as one of the builder's flagship models with 400 hulls completed, celebrated for delivering substantial cruising capability at a budget price in an era of economic flux. At 29 feet 9 inches LOA, with a 25-foot-6-inch waterline, 9-foot-6-inch beam, 8,600-pound displacement, and 3,870 pounds of ballast yielding a high .45 ballast/displacement ratio for stiffness and self-righting prowess, it offers a fixed fin keel drawing 4 feet 8 inches or a centerboard variant (3 feet board-up to 7 feet board-down), paired with a masthead sloop rig (or optional cutter with bowsprit from 1974) providing 390 square feet of sail area for balanced, dry performance up a moderate breeze—though its displacement/length ratio of 232 and SA/D of 14.9 mark it as a steady coastal plodder rather than a racer (PHRF around 180). Built with robust hand-laid fiberglass emphasizing seaworthiness—evidenced by tales of one surviving a four-hour knockdown off Cape Hatteras—the interior boasts 6 feet of headroom, a V-berth forward, enclosed head, U-shaped galley, convertible dinette, and quarter berth for four, complemented by a spacious cockpit and modest tanks (20 gallons water, 18 gallons fuel).
