In terms of size, the 1986 Westerly Oceanlord measures 12.04m (39.5ft) overall with a beam of 3.81m, compared to the 1983 Pearson 31 at 9.45m (31.0ft) with a 3.10m beam. The 1986 Westerly Oceanlord is 2.59m longer than the 1983 Pearson 31. The 1986 Westerly Oceanlord displaces approximately 132% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1986 Westerly Oceanlord has modest sail power for its displacement with an SA/D ratio of 14.90 and 68.0 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 1983 Pearson 31 has the edge in terms of raw sailing performance.

For comfort and safety, the 1986 Westerly Oceanlord offers a moderate motion comfort level (comfort ratio: 23.7) 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 36.4% for the 1986 Westerly Oceanlord and 42.1% for the 1983 Pearson 31, reflecting their respective approaches to stability.

Below deck, the 1986 Westerly Oceanlord provides 7 berths in 3 cabins with 340L of water capacity and 182L of fuel. The 1983 Pearson 31 offers 6 berths in 2 cabins with 114L water and 68L fuel capacity.

Verdict

For cruising: The 1986 Westerly Oceanlord 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 1983 Pearson 31 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The 1986 Westerly Oceanlord offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
