The Catalina 390 is 2.44m longer than the 1988 Pacific Seacraft 31. The Catalina 390 displaces approximately 65% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the Catalina 390 has moderate sail power suitable for relaxed cruising with an SA/D ratio of 16.29 and 65.5 m² of sail area. The 1988 Pacific Seacraft 31, with an SA/D of 14.09 and 40.5 m² of canvas, offers modest sail power for its displacement. The Catalina 390 has the edge in terms of raw sailing performance.

For comfort and safety, the Catalina 390 offers a firm, racing-oriented motion (comfort ratio: 18.9) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.75). The 1988 Pacific Seacraft 31 has a comfort ratio of 26.0 and a capsize screening value of 0.71. The ballast ratios are 39.6% for the Catalina 390 and 43.6% for the 1988 Pacific Seacraft 31, reflecting their respective approaches to stability.

Below deck, the Catalina 390 provides 7 berths in 2 cabins with 265L of water capacity and 114L of fuel. The 1988 Pacific Seacraft 31 offers 5 berths in 2 cabins with 151L water and 76L fuel capacity.

Verdict

For cruising: The 1988 Pacific Seacraft 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 390 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 390 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
