Designed by renowned naval architect William Tripp Jr. and launched in 1968, this classic yawl represents the golden era of fiberglass yacht construction when Seafarer Fiberglass Yachts Inc. was establishing its reputation for quality cruising boats. The masthead yawl rig configuration provides excellent balance and versatility, making this 31-footer particularly well-suited for coastal cruising and moderate offshore passages. With a displacement of 8,750 pounds and substantial ballast of 3,350 pounds, the Seafarer 31 offers the stability and sea-kindly motion that cruising sailors appreciate. The fin keel with rudder on skeg provides a good compromise between performance and directional stability, while the fiberglass construction with balsa-cored deck ensures both strength and reduced weight aloft. The boat's comfort ratio of 29.74 indicates a motion that favors comfort over speed, typical of cruising-oriented designs from this era. Her capsize screening formula of 1.72 suggests good stability for coastal and near-offshore work. The generous sail area of 404 square feet and hull speed of 6.33 knots provide respectable performance for a cruiser of this vintage. This design appeals to sailors seeking a traditional, well-mannered yacht with classic proportions and proven seaworthiness.
