Designed by the renowned British firm Holman & Pye and built by Russell Anstey Yachts, this classic 31-footer represents traditional British yacht design from the mid-1960s. With only 50 hulls produced during its production run beginning in 1965, the Rustler 31 has earned a reputation as a capable offshore cruiser built to exacting standards. The boat's long keel configuration with transom-hung rudder provides excellent directional stability and seakindly motion in rough conditions, making it well-suited for extended coastal cruising and offshore passages. At 12,768 pounds displacement, this substantial yacht offers the weight and momentum needed to punch through seas comfortably. The masthead sloop rig with 440 square feet of sail area provides adequate power while remaining manageable for short-handed sailing. Built from fiberglass construction, the Rustler 31 benefits from the durability and low maintenance requirements of modern materials while retaining classic design proportions. The comfort ratio of 40.3 indicates a motion that prioritizes seaworthiness over speed, while the capsize screening value of 1.54 suggests good stability characteristics for offshore work. Hull speed calculations indicate a theoretical maximum of 6.56 knots, typical for displacement cruisers of this era prioritizing comfort and safety over performance.
