The Catalina 42 MkII, with an SA/D of 17.18 and 76.0 m² of canvas, offers good sail power for versatile performance. The Catalina 42 MkII has the edge in terms of raw sailing performance.

For comfort and safety, the 1963 Cal 40 offers a moderate motion comfort level (comfort ratio: 21.4) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.70). The Catalina 42 MkII has a comfort ratio of 17.4 and a capsize screening value of 0.75. The ballast ratios are 38.7% for the 1963 Cal 40 and 38.1% for the Catalina 42 MkII, reflecting their respective approaches to stability.

Below deck, the 1963 Cal 40 provides 6 berths in 2 cabins with 114L of water capacity and 76L of fuel. The Catalina 42 MkII offers 7 berths in 2 cabins with 303L water and 152L fuel capacity.

Verdict

For cruising: The 1963 Cal 40 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 42 MkII 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 42 MkII offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
