Description
The Bruce Roberts 31, a classic fiberglass cruising sailboat designed by Australian naval architect Bruce Roberts in the 1970s for owner-builders seeking seaworthy coastal and moderate offshore capability, has seen over 100 examples constructed worldwide, celebrated for its multi-chine hull, gaff cutter rig, and versatile accommodations in a compact package ideal for solo sailors, couples, or small families. Measuring 31 feet 11 inches LOA with a 24-foot-2-inch LWL, 10-foot beam, 4-foot-6-inch draft on a long keel for stability, and a displacement of 14,200 pounds, this vessel offers an estimated sail area of around 500 square feet across mainsail and headsails for efficient performance in 10-25 knot winds, achieving 5.5-7 knot hull speeds with responsive handling, complemented by a 20- to 30-horsepower auxiliary diesel like the Yanmar 3GM. Its traditional lines feature a clipper bow, moderate sheer, and trunk cabin options, paired with a cozy interior boasting 6-foot headroom, layouts for four to six berths including V-berth forward, saloon settee, quarter berth aft, compact galley, and enclosed head, plus modest tankage of 40-60 gallons fuel and water for weekend-to-weeklong autonomy. Proven in ambitious voyages—from Australian waters to Japan, China, Canada, and trans-U.S. passages—as in early builds like those documented in Roberts' plans, the 31 delivers big-boat virtues of durability and satisfaction in a trailerable, budget-friendly design, remaining a staple for aspiring cruisers valuing simplicity and adventure.
