Detailed Comparison

The 1990 Contest 40S and 1983 Pearson 31 represent two takes on sloop-rigged sailing. The 1990 Contest 40S is a 1990s design by Contest from Netherlands, while the 1983 Pearson 31 is a 1980s offering from Pearson from USA. The 1990 Contest 40S was penned by Dick Zaal. The 1983 Pearson 31 was designed by William Shaw.

In terms of size, the 1990 Contest 40S measures 12.25m (40.2ft) overall with a beam of 3.72m, compared to the 1983 Pearson 31 at 9.45m (31.0ft) with a 3.10m beam. The 1990 Contest 40S is 2.80m longer than the 1983 Pearson 31. The 1990 Contest 40S displaces approximately 111% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1990 Contest 40S has moderate sail power suitable for relaxed cruising with an SA/D ratio of 16.00 and 68.5 m² of sail area. The 1983 Pearson 31, with an SA/D of 15.35 and 40.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The 1990 Contest 40S has the edge in terms of raw sailing performance.

For comfort and safety, the 1990 Contest 40S offers a moderate motion comfort level (comfort ratio: 21.1) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.71). The 1983 Pearson 31 has a comfort ratio of 21.4 and a capsize screening value of 0.76. The ballast ratios are 40.0% for the 1990 Contest 40S and 42.1% for the 1983 Pearson 31, reflecting their respective approaches to stability.

Below deck, the 1990 Contest 40S provides 6 berths in 2 cabins with 400L of water capacity and 250L of fuel. The 1983 Pearson 31 offers 6 berths in 2 cabins with 114L water and 68L fuel capacity.

Verdict

For cruising: The 1983 Pearson 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 1990 Contest 40S has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: Both boats provide similar accommodation, making either a viable choice for living aboard. Consider water and fuel capacity for extended stays away from marinas.
