In terms of size, the Catalina 250 measures 7.62m (25.0ft) overall with a beam of 2.59m, compared to the Dufour 310 Grand Large at 9.43m (30.9ft) with a 3.13m beam. The Dufour 310 Grand Large is 1.81m longer than the Catalina 250. The Dufour 310 Grand Large displaces approximately 161% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the Catalina 250 has good sail power for versatile performance with an SA/D ratio of 18.30 and 24.5 m² of sail area. The Dufour 310 Grand Large, with an SA/D of 15.74 and 40.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The Catalina 250 has the edge in terms of raw sailing performance.

For comfort and safety, the Catalina 250 offers a firm, racing-oriented motion (comfort ratio: 13.9) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.89). The Dufour 310 Grand Large has a comfort ratio of 18.3 and a capsize screening value of 0.78. The ballast ratios are 38.5% for the Catalina 250 and 29.6% for the Dufour 310 Grand Large, reflecting their respective approaches to stability.

Below deck, the Catalina 250 provides 4 berths in 1 cabin with 42L of water capacity and 30L of fuel. The Dufour 310 Grand Large offers 4 berths in 1 cabin with 120L water and 80L fuel capacity.

Verdict

For cruising: The Dufour 310 Grand Large 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 250 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.
