In terms of size, the Catalina 270 measures 8.31m (27.3ft) overall with a beam of 2.74m, compared to the Catalina 315 at 9.45m (31.0ft) with a 3.20m beam. The Catalina 315 is 1.14m longer than the Catalina 270. The Catalina 315 displaces approximately 96% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the Catalina 270 has good sail power for versatile performance with an SA/D ratio of 18.01 and 31.0 m² of sail area. The Catalina 315, with an SA/D of 16.32 and 44.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The Catalina 270 has the edge in terms of raw sailing performance.

For comfort and safety, the Catalina 270 offers a firm, racing-oriented motion (comfort ratio: 16.2) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.83). The Catalina 315 has a comfort ratio of 18.9 and a capsize screening value of 0.77. The ballast ratios are 39.2% for the Catalina 270 and 40.0% for the Catalina 315, reflecting their respective approaches to stability.

Below deck, the Catalina 270 provides 5 berths in 1 cabin with 68L of water capacity and 45L of fuel. The Catalina 315 offers 5 berths in 1 cabin with 132L water and 76L fuel capacity.

Verdict

For cruising: The Catalina 315 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 270 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.
