About the Sigma 292 Sailboat

Designed by David Thomas and built by Marine Projects Ltd. in the UK, this 29-footer represents a well-balanced approach to coastal cruising and club racing from the early 1980s. With only 30 hulls produced starting in 1983, the Sigma 292 remains a relatively rare find in today's market. The boat's fractional sloop rig and fin keel with spade rudder configuration delivers responsive handling characteristics that appeal to performance-minded sailors. Her 18.79 sail area to displacement ratio suggests spirited sailing ability, while the moderate displacement of 6,600 pounds strikes a practical balance between speed and stability. The 41% ballast-to-displacement ratio provides adequate stiffness for confident sailing in varying conditions. At 23 feet on the waterline with a theoretical hull speed of 6.43 knots, the 292 offers respectable pace for coastal passages and weekend cruising. Her comfort ratio of 18.95 indicates a relatively quick motion suited to active sailing rather than heavy-weather passagemaking, while the capsize screening formula of 2.15 falls within acceptable limits for coastal and near-offshore sailing. The fiberglass construction and David Thomas pedigree suggest solid build quality, making surviving examples potentially attractive options for sailors seeking a capable, performance-oriented coastal cruiser with distinctive British character.
