Detailed Comparison

The 1965 Bristol 35.5 and Catalina 270 represent two takes on sloop-rigged sailing. The 1965 Bristol 35.5 is a classic design by Bristol from USA, while the Catalina 270 is a 1990s offering from Catalina from USA. The 1965 Bristol 35.5 was penned by Halsey Herreshoff. The Catalina 270 was designed by Gerry Douglas.

In terms of size, the 1965 Bristol 35.5 measures 10.82m (35.5ft) overall with a beam of 2.97m, compared to the Catalina 270 at 8.31m (27.3ft) with a 2.74m beam. The 1965 Bristol 35.5 is 2.51m longer than the Catalina 270. The 1965 Bristol 35.5 displaces approximately 155% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1965 Bristol 35.5 has modest sail power for its displacement with an SA/D ratio of 14.75 and 47.4 m² of sail area. The Catalina 270, with an SA/D of 18.01 and 31.0 m² of canvas, offers good sail power for versatile performance. The Catalina 270 has the edge in terms of raw sailing performance.

For comfort and safety, the 1965 Bristol 35.5 offers a moderate motion comfort level (comfort ratio: 28.9) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.66). The Catalina 270 has a comfort ratio of 16.2 and a capsize screening value of 0.83. The ballast ratios are 41.5% for the 1965 Bristol 35.5 and 39.2% for the Catalina 270, reflecting their respective approaches to stability.

Below deck, the 1965 Bristol 35.5 provides 6 berths in 2 cabins with 114L of water capacity and 57L of fuel. The Catalina 270 offers 5 berths in 1 cabin with 68L water and 45L fuel capacity.

Verdict

For cruising: The 1965 Bristol 35.5 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 270 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The 1965 Bristol 35.5 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
