Launched during a brief two-year production run from 1990-1991, this rare 55-footer represents Bruce Marek's vision of a performance-oriented cruising yacht built by the respected W. D. Schock Corporation. With only two hulls ever constructed, the Schock 55 stands as an exclusive entry in the world of fiberglass cruising sailboats. The design showcases classic early-1990s thinking with its fin keel and spade rudder configuration, delivering the responsiveness expected from a performance cruiser. At 18,500 pounds displacement with 8,300 pounds of ballast, the yacht strikes a balance between stability and speed, while the masthead sloop rig provides versatile sail handling options for both short-handed and fully-crewed sailing. The boat's proportions suggest capable offshore performance, with enough waterline length to generate respectable passage times and sufficient beam to provide comfortable interior volume. The substantial draft indicates serious cruising intentions rather than shoal-water coastal sailing. Given Schock's reputation for building quality production boats and Marek's design expertise, this model likely appeals to sailors seeking a well-built platform for extended cruising with performance characteristics that won't disappoint when conditions favor sailing over motoring.
