Designed by the respected team of Graham & Schlageter, this mid-1980s cruiser represents a thoughtful balance between performance and comfort for coastal and offshore sailing. Built by Thomas Marine Inc. and later Tartan Marine, the boat features a modern fin keel with spade rudder configuration that delivers responsive handling while maintaining the stability needed for extended cruising. The fractional sloop rig provides excellent sail handling characteristics, making it well-suited for both shorthanded cruising and spirited coastal sailing. With a displacement of 9,800 pounds and 4,450 pounds of ballast, this fiberglass construction offers reassuring stability without sacrificing sailing performance. The sail area to displacement ratio of 24.61 indicates a boat that will move well in moderate conditions while remaining manageable in stronger winds. The comfort ratio of 18.31 suggests this design prioritizes sailing performance over ultimate interior volume, typical of boats from this era that emphasized seaworthiness and sailing ability. The capsize screening value of 2.15 falls within acceptable parameters for offshore sailing, while the hull speed of 7.40 knots provides realistic expectations for passage planning. This makes it an excellent choice for sailors seeking a capable coastal cruiser with occasional offshore potential.
