The Catalina 28, with an SA/D of 17.09 and 33.5 m² of canvas, offers good sail power for versatile performance. The 1979 O'Day 25 has the edge in terms of raw sailing performance.

For comfort and safety, the 1979 O'Day 25 offers a firm, racing-oriented motion (comfort ratio: 16.0) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.91). The Catalina 28 has a comfort ratio of 16.6 and a capsize screening value of 0.82. The ballast ratios are 41.0% for the 1979 O'Day 25 and 40.3% for the Catalina 28, reflecting their respective approaches to stability.

Below deck, the 1979 O'Day 25 provides 5 berths in 1 cabin with 45L of water capacity and 30L of fuel. The Catalina 28 offers 6 berths in 1 cabin with 95L water and 57L fuel capacity.

Verdict

For cruising: The Catalina 28 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 1979 O'Day 25 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 28 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
