Detailed Comparison

The 1975 Pearson 39 and 1986 Westerly Oceanlord represent two takes on sloop-rigged sailing. The 1975 Pearson 39 is a 1970s design by Pearson from USA, while the 1986 Westerly Oceanlord is a 1980s offering from Westerly from UK. The 1975 Pearson 39 was penned by William Shaw. The 1986 Westerly Oceanlord was designed by Ed Dubois.

In terms of size, the 1975 Pearson 39 measures 11.89m (39.0ft) overall with a beam of 3.51m, compared to the 1986 Westerly Oceanlord at 12.04m (39.5ft) with a 3.81m beam. The 1986 Westerly Oceanlord is 0.15m longer than the 1975 Pearson 39. The 1986 Westerly Oceanlord displaces approximately 29% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1975 Pearson 39 has moderate sail power suitable for relaxed cruising with an SA/D ratio of 15.83 and 60.8 m² of sail area. The 1986 Westerly Oceanlord, with an SA/D of 14.90 and 68.0 m² of canvas, offers modest sail power for its displacement. The 1975 Pearson 39 has the edge in terms of raw sailing performance.

For comfort and safety, the 1975 Pearson 39 offers a moderate motion comfort level (comfort ratio: 21.5) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.71). The 1986 Westerly Oceanlord has a comfort ratio of 23.7 and a capsize screening value of 0.71. The ballast ratios are 41.2% for the 1975 Pearson 39 and 36.4% for the 1986 Westerly Oceanlord, reflecting their respective approaches to stability.

Below deck, the 1975 Pearson 39 provides 7 berths in 2 cabins with 189L of water capacity and 114L of fuel. The 1986 Westerly Oceanlord offers 7 berths in 3 cabins with 340L water and 182L 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 1975 Pearson 39 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.
