Detailed Comparison

The 1972 Contest 31 and 1997 Tartan 3700 represent two takes on sloop-rigged sailing. The 1972 Contest 31 is a 1970s design by Contest from Netherlands, while the 1997 Tartan 3700 is a 1990s offering from Tartan from USA. The 1972 Contest 31 was penned by Dick Zaal. The 1997 Tartan 3700 was designed by Tim Jackett.

In terms of size, the 1972 Contest 31 measures 9.45m (31.0ft) overall with a beam of 3.05m, compared to the 1997 Tartan 3700 at 11.28m (37.0ft) with a 3.66m beam. The 1997 Tartan 3700 is 1.83m longer than the 1972 Contest 31. The 1997 Tartan 3700 displaces approximately 55% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1972 Contest 31 has modest sail power for its displacement with an SA/D ratio of 14.65 and 39.5 m² of sail area. The 1997 Tartan 3700, with an SA/D of 17.16 and 62.0 m² of canvas, offers good sail power for versatile performance. The 1997 Tartan 3700 has the edge in terms of raw sailing performance.

For comfort and safety, the 1972 Contest 31 offers a moderate motion comfort level (comfort ratio: 23.7) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.74). The 1997 Tartan 3700 has a comfort ratio of 18.4 and a capsize screening value of 0.77. The ballast ratios are 40.0% for the 1972 Contest 31 and 41.9% for the 1997 Tartan 3700, reflecting their respective approaches to stability.

Below deck, the 1972 Contest 31 provides 5 berths in 2 cabins with 150L of water capacity and 80L of fuel. The 1997 Tartan 3700 offers 6 berths in 2 cabins with 220L water and 130L 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 1997 Tartan 3700 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The 1997 Tartan 3700 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
