Detailed Comparison

The 1990 J/40 and Catalina 42 MkII represent two takes on sloop-rigged sailing. The 1990 J/40 is a 1990s design by J/Boats from USA, while the Catalina 42 MkII is a 2000s offering from Catalina from USA. The 1990 J/40 was penned by Rod Johnstone. The Catalina 42 MkII was designed by Gerry Douglas.

In terms of size, the 1990 J/40 measures 12.30m (40.4ft) overall with a beam of 3.65m, compared to the Catalina 42 MkII at 12.80m (42.0ft) with a 3.96m beam. The Catalina 42 MkII is 0.50m longer than the 1990 J/40. The Catalina 42 MkII displaces approximately 24% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1990 J/40 has good sail power for versatile performance with an SA/D ratio of 18.87 and 72.5 m² of sail area. 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 1990 J/40 has the edge in terms of raw sailing performance.

For comfort and safety, the 1990 J/40 offers a firm, racing-oriented motion (comfort ratio: 18.0) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.74). The Catalina 42 MkII has a comfort ratio of 17.4 and a capsize screening value of 0.75. The ballast ratios are 44.1% for the 1990 J/40 and 38.1% for the Catalina 42 MkII, reflecting their respective approaches to stability.

Below deck, the 1990 J/40 provides 6 berths in 2 cabins with 189L of water capacity and 114L of fuel. The Catalina 42 MkII offers 7 berths in 2 cabins with 303L water and 152L fuel capacity.

Verdict

For cruising: The 1990 J/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 1990 J/40 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.
