Detailed Comparison

The 1984 J/29 and Catalina 34 MkII represent two takes on sloop-rigged sailing. The 1984 J/29 is a 1980s design by J/Boats from USA, while the Catalina 34 MkII is a 1990s offering from Catalina from USA. The 1984 J/29 was penned by Rod Johnstone. The Catalina 34 MkII was designed by Gerry Douglas.

In terms of size, the 1984 J/29 measures 8.99m (29.5ft) overall with a beam of 3.28m, compared to the Catalina 34 MkII at 10.36m (34.0ft) with a 3.40m beam. The Catalina 34 MkII is 1.37m longer than the 1984 J/29. The Catalina 34 MkII displaces approximately 67% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1984 J/29 has good sail power for versatile performance with an SA/D ratio of 18.97 and 41.1 m² of sail area. The Catalina 34 MkII, with an SA/D of 17.08 and 52.0 m² of canvas, offers good sail power for versatile performance. The 1984 J/29 has the edge in terms of raw sailing performance.

For comfort and safety, the 1984 J/29 offers a firm, racing-oriented motion (comfort ratio: 16.0) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.89). The Catalina 34 MkII has a comfort ratio of 18.1 and a capsize screening value of 0.77. The ballast ratios are 45.8% for the 1984 J/29 and 37.5% for the Catalina 34 MkII, reflecting their respective approaches to stability.

Below deck, the 1984 J/29 provides 5 berths in 1 cabin with 38L of water capacity and 38L of fuel. The Catalina 34 MkII offers 6 berths in 2 cabins with 151L water and 76L fuel capacity.

Verdict

For cruising: The Catalina 34 MkII 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 1984 J/29 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 34 MkII offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
