Designed by Peter Brett and built by Marine Construction (UK) starting in 1969, this 31-footer represents classic British yacht design philosophy emphasizing seaworthiness and solid construction. The Rival 31's fiberglass hull features a fin keel with rudder on skeg configuration, providing good directional stability while maintaining reasonable performance under sail. With a displacement of 11,200 pounds and 4,480 pounds of ballast, this masthead sloop carries the weight and stability characteristics that make it well-suited for serious coastal cruising and limited offshore passages. The comfort ratio of 31.86 indicates a motion that's on the moderate side—stiff enough for confident sailing yet comfortable for extended cruising. The capsize screening formula of 1.73 falls within acceptable parameters for offshore capability, though the design clearly prioritizes seaworthiness over pure speed. The Rival 31's proportions, with a 24.50-foot waterline length and 9.67-foot beam, create a balanced platform that should handle a variety of conditions competently. Hull speed calculations suggest a maximum of 6.63 knots under ideal conditions. This yacht appeals to sailors seeking a dependable, well-built cruiser that emphasizes safety and comfort over racing performance, making it particularly attractive for couples or small families planning coastal adventures.
