Detailed Comparison

The 1973 Ericson 27 and Catalina 315 represent two takes on sloop-rigged sailing. The 1973 Ericson 27 is a 1970s design by Ericson from USA, while the Catalina 315 is a modern offering from Catalina from USA. The 1973 Ericson 27 was penned by Bruce King. The Catalina 315 was designed by Gerry Douglas.

In terms of size, the 1973 Ericson 27 measures 8.23m (27.0ft) overall with a beam of 2.74m, compared to the Catalina 315 at 9.45m (31.0ft) with a 3.20m beam. The Catalina 315 is 1.22m longer than the 1973 Ericson 27. The Catalina 315 displaces approximately 82% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1973 Ericson 27 has good sail power for versatile performance with an SA/D ratio of 17.02 and 30.8 m² of sail area. The Catalina 315, with an SA/D of 16.32 and 44.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The 1973 Ericson 27 has the edge in terms of raw sailing performance.

For comfort and safety, the 1973 Ericson 27 offers a moderate motion comfort level (comfort ratio: 20.1) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.81). The Catalina 315 has a comfort ratio of 18.9 and a capsize screening value of 0.77. The ballast ratios are 41.8% for the 1973 Ericson 27 and 40.0% for the Catalina 315, reflecting their respective approaches to stability.

Below deck, the 1973 Ericson 27 provides 5 berths in 1 cabin with 57L of water capacity and 38L of fuel. The Catalina 315 offers 5 berths in 1 cabin with 132L water and 76L fuel capacity.

Verdict

For cruising: The 1973 Ericson 27 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 1973 Ericson 27 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.
