In terms of size, the 1970 Bristol 32 measures 9.75m (32.0ft) overall with a beam of 2.97m, compared to the Dufour 32 Classic at 9.70m (31.8ft) with a 3.20m beam. The 1970 Bristol 32 is 0.05m longer than the Dufour 32 Classic. The 1970 Bristol 32 displaces approximately 1% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1970 Bristol 32 has modest sail power for its displacement with an SA/D ratio of 14.91 and 40.2 m² of sail area. The Dufour 32 Classic, with an SA/D of 16.78 and 45.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The Dufour 32 Classic has the edge in terms of raw sailing performance.

For comfort and safety, the 1970 Bristol 32 offers a moderate motion comfort level (comfort ratio: 26.0) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.72). The Dufour 32 Classic has a comfort ratio of 19.0 and a capsize screening value of 0.78. The ballast ratios are 42.0% for the 1970 Bristol 32 and 31.1% for the Dufour 32 Classic, reflecting their respective approaches to stability.

Below deck, the 1970 Bristol 32 provides 5 berths in 1 cabin with 76L of water capacity and 57L of fuel. The Dufour 32 Classic offers 6 berths in 2 cabins with 150L water and 80L fuel capacity.

Verdict

For cruising: The 1970 Bristol 32 is the better choice for comfortable cruising thanks to its higher comfort ratio, offering a gentler motion at sea that crews will appreciate on longer passages.

For racing: The Dufour 32 Classic has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The Dufour 32 Classic offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
