Detailed Comparison

The 1975 Pearson 39 and 1981 Nautor Swan 36 represent two takes on sloop-rigged sailing. The 1975 Pearson 39 is a 1970s design by Pearson from USA, while the 1981 Nautor Swan 36 is a 1980s offering from Nautor Swan from Finland. The 1975 Pearson 39 was penned by William Shaw. The 1981 Nautor Swan 36 was designed by Sparkman & Stephens.

In terms of size, the 1975 Pearson 39 measures 11.89m (39.0ft) overall with a beam of 3.51m, compared to the 1981 Nautor Swan 36 at 10.97m (36.0ft) with a 3.35m beam. The 1975 Pearson 39 is 0.92m longer than the 1981 Nautor Swan 36. The 1975 Pearson 39 displaces approximately 21% 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 1981 Nautor Swan 36, with an SA/D of 16.15 and 54.5 m² of canvas, offers moderate sail power suitable for relaxed cruising. The 1981 Nautor Swan 36 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 1981 Nautor Swan 36 has a comfort ratio of 22.7 and a capsize screening value of 0.72. The ballast ratios are 41.2% for the 1975 Pearson 39 and 42.9% for the 1981 Nautor Swan 36, 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 1981 Nautor Swan 36 offers 6 berths in 2 cabins with 180L water and 100L fuel capacity.

Verdict

For cruising: The 1981 Nautor Swan 36 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 1981 Nautor Swan 36 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The 1975 Pearson 39 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
