Detailed Comparison

The Catalina 36 MkII and 1979 Cal 39 represent two takes on sloop-rigged sailing. The Catalina 36 MkII is a 1990s design by Catalina from USA, while the 1979 Cal 39 is a 1970s offering from Cal from USA. The Catalina 36 MkII was penned by Gerry Douglas. The 1979 Cal 39 was designed by Bill Lapworth / C. Raymond Hunt.

In terms of size, the Catalina 36 MkII measures 10.97m (36.0ft) overall with a beam of 3.55m, compared to the 1979 Cal 39 at 11.89m (39.0ft) with a 3.66m beam. The 1979 Cal 39 is 0.92m longer than the Catalina 36 MkII. The 1979 Cal 39 displaces approximately 24% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the Catalina 36 MkII has moderate sail power suitable for relaxed cruising with an SA/D ratio of 16.35 and 56.5 m² of sail area. The 1979 Cal 39, with an SA/D of 15.78 and 63.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The Catalina 36 MkII has the edge in terms of raw sailing performance.

For comfort and safety, the Catalina 36 MkII offers a firm, racing-oriented motion (comfort ratio: 18.7) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.76). The 1979 Cal 39 has a comfort ratio of 21.1 and a capsize screening value of 0.73. The ballast ratios are 37.9% for the Catalina 36 MkII and 41.7% for the 1979 Cal 39, reflecting their respective approaches to stability.

Below deck, the Catalina 36 MkII provides 7 berths in 2 cabins with 189L of water capacity and 95L of fuel. The 1979 Cal 39 offers 7 berths in 2 cabins with 200L water and 114L fuel capacity.

Verdict

For cruising: The 1979 Cal 39 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 36 MkII 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.
