DescriptionThe Sigma 33 is a highly regarded British cruiser-racer, combining excellent sailing performance with a strong, proven hull design. Designed by David Thomas and built by Marine Projects, the 33 offers responsive handling, good speed and impressive seaworthiness, making her equally capable for competitive club racing or comfortable cruising. Her spacious and practical accommodation provides genuine cruising capability, while her relatively moderate displacement and well-balanced sailing characteristics make her enjoyable to sail short-handed. The Sigma 33’s enduring popularity is testament to the quality of her design, construction and performance, making this 1982 example an attractive opportunity for sailors seeking a capable, rewarding and proven yacht.
