Detailed Comparison

The Catalina 387 and 1983 Pearson 31 represent two takes on sloop-rigged sailing. The Catalina 387 is a 1990s design by Catalina from USA, while the 1983 Pearson 31 is a 1980s offering from Pearson from USA. The Catalina 387 was penned by Gerry Douglas. The 1983 Pearson 31 was designed by William Shaw.

In terms of size, the Catalina 387 measures 11.58m (38.0ft) overall with a beam of 3.66m, compared to the 1983 Pearson 31 at 9.45m (31.0ft) with a 3.10m beam. The Catalina 387 is 2.13m longer than the 1983 Pearson 31. The Catalina 387 displaces approximately 74% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the Catalina 387 has moderate sail power suitable for relaxed cruising with an SA/D ratio of 16.73 and 63.0 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 Catalina 387 has the edge in terms of raw sailing performance.

For comfort and safety, the Catalina 387 offers a firm, racing-oriented motion (comfort ratio: 18.5) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.75). The 1983 Pearson 31 has a comfort ratio of 21.4 and a capsize screening value of 0.76. The ballast ratios are 39.4% for the Catalina 387 and 42.1% for the 1983 Pearson 31, reflecting their respective approaches to stability.

Below deck, the Catalina 387 provides 7 berths in 2 cabins with 227L of water capacity and 114L 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 Catalina 387 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The Catalina 387 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
