In terms of size, the Catalina 315 measures 9.45m (31.0ft) overall with a beam of 3.20m, compared to the Catalina 390 at 11.89m (39.0ft) with a 3.76m beam. The Catalina 390 is 2.44m longer than the Catalina 315. The Catalina 390 displaces approximately 82% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the Catalina 315 has moderate sail power suitable for relaxed cruising with an SA/D ratio of 16.32 and 44.0 m² of sail area. The Catalina 390, with an SA/D of 16.29 and 65.5 m² of canvas, offers moderate sail power suitable for relaxed cruising. The Catalina 315 has the edge in terms of raw sailing performance.

For comfort and safety, the Catalina 315 offers a firm, racing-oriented motion (comfort ratio: 18.9) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.77). The Catalina 390 has a comfort ratio of 18.9 and a capsize screening value of 0.75. The ballast ratios are 40.0% for the Catalina 315 and 39.6% for the Catalina 390, reflecting their respective approaches to stability.

Below deck, the Catalina 315 provides 5 berths in 1 cabin with 132L of water capacity and 76L of fuel. The Catalina 390 offers 7 berths in 2 cabins with 265L water and 114L fuel capacity.

Verdict

For cruising: The Catalina 390 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 315 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.
