About the Spartan 2 Buchanan Sailboat

Designed by Alan Buchanan in 1955, this classic 23-footer represents the era's emphasis on seaworthy construction and traditional sailing qualities. With only 50 hulls built, the Spartan 2 has become a relatively rare find among vintage sailboat enthusiasts seeking authentic mid-century design and craftsmanship. The boat's substantial displacement of 5,500 pounds and deep 4-foot draft create a stable platform well-suited for coastal cruising and longer passages. Her impressive ballast-to-displacement ratio of over 60 percent, combined with a traditional long keel configuration, delivers exceptional directional stability and seakindly motion in challenging conditions. The carvel-planked wooden construction reflects the high standards of 1950s boatbuilding, though prospective owners should budget for the ongoing maintenance that wooden hulls require. Her fractional sloop rig with 250 square feet of sail area provides adequate power while remaining manageable for small crews. The comfort ratio of 35.57 indicates excellent motion characteristics for extended cruising, while the capsize screening value of 1.48 suggests good stability for offshore work. Hull speed calculations show she'll cruise efficiently at around 5.7 knots, making her ideal for sailors who prioritize comfort and seaworthiness over pure speed.
