In terms of size, the 1973 Tartan 34 measures 10.36m (34.0ft) overall with a beam of 3.05m, compared to the Catalina 270 at 8.31m (27.3ft) with a 2.74m beam. The 1973 Tartan 34 is 2.05m longer than the Catalina 270. The 1973 Tartan 34 displaces approximately 135% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1973 Tartan 34 has moderate sail power suitable for relaxed cruising with an SA/D ratio of 15.27 and 46.5 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 1973 Tartan 34 offers a moderate motion comfort level (comfort ratio: 27.3) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.69). The Catalina 270 has a comfort ratio of 16.2 and a capsize screening value of 0.83. The ballast ratios are 45.0% for the 1973 Tartan 34 and 39.2% for the Catalina 270, reflecting their respective approaches to stability.

Below deck, the 1973 Tartan 34 provides 6 berths in 2 cabins with 114L of water capacity and 76L of fuel. The Catalina 270 offers 5 berths in 1 cabin with 68L water and 45L fuel capacity.

Verdict

For cruising: The 1973 Tartan 34 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 1973 Tartan 34 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
