About the Beverly Dinghy Sailboat

Designed by the legendary Sidney Herreshoff and built by Cape Cod Shipbuilding starting in 1953, this classic 11.5-foot dinghy represents traditional New England craftsmanship at its finest. With 500 hulls produced over its production run, the Beverly Dinghy earned a solid reputation among small boat sailors seeking reliable coastal performance. The cat-rigged design features a simple yet effective Marconi sail plan with 66 square feet of canvas, making it ideal for day sailing, sailing instruction, and light recreational use in protected waters. Its moderate beam of 4.5 feet provides stability while maintaining easy handling characteristics that appeal to both novice and experienced sailors. The centerboard configuration allows for shallow water exploration and simplified launching from beaches. Construction combines traditional wood with fiberglass reinforcement, offering durability while preserving classic aesthetics. At 207 pounds displacement, the Beverly remains light enough for car-topping yet substantial enough to handle moderate chop. The sail area to displacement ratio of 30.2 indicates spirited performance in light to moderate winds, while the capsize screening value of 3.04 suggests appropriate stability for its intended coastal sailing applications. This dinghy excels as a tender, trainer, or weekend explorer for sailors who appreciate timeless design and proven seaworthiness.
