About the San Juan 29 Sailboat

Designed by Don Clark and built by San Juan Manufacturing beginning in 1984, this 29-footer represents a solid entry into the popular cruiser-racer category of the mid-1980s. The boat's fin keel and spade rudder configuration delivers responsive handling characteristics that appeal to sailors seeking both weekend cruising comfort and occasional racing performance. With a displacement of 6,200 pounds and a substantial ballast ratio provided by 3,100 pounds of ballast, the San Juan 29 offers reassuring stability for coastal cruising and moderate offshore passages. The masthead sloop rig carries 383 square feet of sail area, providing adequate power in light to moderate conditions while remaining manageable for small crews. The boat's fiberglass construction reflects the reliable building standards of its era, while the 10-foot beam provides comfortable interior volume without sacrificing sailing performance. A comfort ratio of 18.38 suggests this design favors spirited sailing over ultimate cruising luxury, making it well-suited for active sailors who prioritize boat handling over spacious accommodations. The San Juan 29 earned recognition as a versatile coastal cruiser capable of club racing, offering new sailors an accessible path into performance-oriented sailing while providing experienced crews with a responsive, seaworthy platform for extended coastal adventures.
