About the Wasa Atlantic 51 Sailboat

Designed by Swedish naval architect Leif Ängermark and built by Wasa Marin A.B., this impressive 50-foot cruiser emerged from Sweden's rich boatbuilding tradition in 1983. The Atlantic 51 represents a thoughtful balance between performance and comfort, making it well-suited for serious offshore cruising and extended passages. The yacht's fractional sloop rig and fin keel with spade rudder configuration delivers responsive handling while maintaining the stability needed for long-distance voyaging. With a displacement of 22,500 pounds and 8,350 pounds of ballast, she offers the substantial feel that experienced cruisers appreciate in challenging conditions. The sail area to displacement ratio of 17.88 indicates moderate performance characteristics that prioritize reliability over racing speed. Her fiberglass construction ensures durability, while the comfort ratio of 32.48 suggests a motion that's gentle enough for extended passages without being sluggish. The capsize screening formula of 1.54 falls within acceptable parameters for offshore work, though careful attention to weather routing remains prudent. The 36-horsepower auxiliary engine provides adequate power for maneuvering in harbors and motoring through calms. Overall, the Atlantic 51 appeals to sailors seeking a capable, well-built platform for serious coastal and offshore cruising adventures.
