1979 CAL 31

This 1979 Cal 31 is a 31.5-foot masthead sloop designed by C. William Lapworth, featuring a fiberglass hull with a fin keel and spade rudder. The boat displaces 9,170 pounds and carries 3,600 pounds of ballast, giving it a solid 39.26 ballast-displacement ratio. With a 10-foot beam and 5-foot draft, it performs well in cruising and racing conditions typical of the Puget Sound.

The boat is equipped with a 20-horsepower Perkins diesel engine for fuel-efficient auxiliary power. The electronics and sailing systems are notably comprehensive: a rigid boom vang, roller furler, autopilot, self-tailing winches, navigation equipment, and a windlass all support practical, manageable sailing. A Wallas stove and heater provide comfort underway, and a single head serves the interior.

The layout includes a V-berth forward, a main salon with bench seating and additional berths, and a galley with sink and stove, making the accommodation thoughtful for its size. The design carries a reputation for solid construction and responsive handling, with the boat performing well across a range of conditions.
