In terms of size, the Beneteau First 40 measures 12.16m (39.9ft) overall with a beam of 3.80m, compared to the 1972 Contest 31 at 9.45m (31.0ft) with a 3.05m beam. The Beneteau First 40 is 2.71m longer than the 1972 Contest 31. The Beneteau First 40 displaces approximately 54% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the Beneteau First 40 has generous sail power for spirited sailing with an SA/D ratio of 20.55 and 74.0 m² of sail area. The 1972 Contest 31, with an SA/D of 14.65 and 39.5 m² of canvas, offers modest sail power for its displacement. The Beneteau First 40 has the edge in terms of raw sailing performance.

For comfort and safety, the Beneteau First 40 offers a firm, racing-oriented motion (comfort ratio: 14.9) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.80). The 1972 Contest 31 has a comfort ratio of 23.7 and a capsize screening value of 0.74. The ballast ratios are 35.7% for the Beneteau First 40 and 40.0% for the 1972 Contest 31, reflecting their respective approaches to stability.

Below deck, the Beneteau First 40 provides 8 berths in 3 cabins with 280L of water capacity and 150L of fuel. The 1972 Contest 31 offers 5 berths in 2 cabins with 150L water and 80L fuel capacity.

Verdict

For cruising: The 1972 Contest 31 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 Beneteau First 40 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The Beneteau First 40 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
