Designed by the collaborative team of Robin Chadworth-Musters and Alan Gurney, this British-built cruising yacht emerged from Tyler Boat Works in 1978 as a thoughtful answer to serious offshore sailing demands. The Slipper 42 embodies classic late-1970s design philosophy with its masthead ketch rig and fin keel configuration paired with a rudder mounted on a protective skeg. With a displacement of 16,500 pounds and substantial ballast ratio, this fiberglass yacht prioritizes seaworthiness over speed, making it particularly well-suited for extended coastal cruising and offshore passages. The generous beam of 12.25 feet provides excellent stability and interior volume, while the moderate draft allows access to a reasonable range of harbors and anchorages. The ketch rig offers versatility in heavy weather conditions, allowing sailors to reduce sail area by dropping the mainsail while maintaining balance under mizzen and headsail alone. This configuration, combined with the boat's conservative comfort ratio of 26.79, suggests a yacht designed for those who value safety and comfort over racing performance. Tyler Boat Works' reputation for solid construction translates into a robust cruising platform capable of handling challenging conditions with confidence, making the Slipper 42 an appealing choice for serious cruising sailors seeking a proven offshore design.
