About the Warrior Iii Primrose Sailboat

Designed by the renowned British naval architect Angus Primrose and first launched in 1969, this 35-foot sailboat represents classic British yacht design from the late 1960s. Built by Garder Marine Ltd. in the UK and later by Trident Marine, the Warrior III showcases traditional fiberglass construction with thoughtful proportions that have stood the test of time. With her moderate displacement of 12,350 pounds and substantial ballast ratio, this masthead sloop offers excellent stability and seaworthiness for coastal cruising and light offshore passages. The fin keel configuration provides good pointing ability while maintaining reasonable draft for accessing shallow harbors. Her beam of 10.50 feet creates comfortable interior volume without sacrificing sailing performance. The sail area to displacement ratio of 13.13 indicates moderate power, making her well-suited for cruising sailors who value comfort over racing performance. The low comfort ratio of 28.98 suggests a relatively stiff motion at sea, while the capsize screening formula of 1.82 falls within acceptable limits for coastal and near-shore sailing. Angus Primrose's design philosophy emphasized seaworthiness and practical sailing characteristics, qualities clearly evident in this boat's balanced proportions and enduring popularity among cruising sailors seeking a proven, traditional design.
