Detailed Comparison

The Catalina 315 and 1984 Cape Dory 33 represent two takes on sloop-rigged sailing. The Catalina 315 is a modern design by Catalina from USA, while the 1984 Cape Dory 33 is a 1980s offering from Cape Dory from USA. The Catalina 315 was penned by Gerry Douglas. The 1984 Cape Dory 33 was designed by Carl Alberg.

In terms of size, the Catalina 315 measures 9.45m (31.0ft) overall with a beam of 3.20m, compared to the 1984 Cape Dory 33 at 10.06m (33.0ft) with a 3.12m beam. The 1984 Cape Dory 33 is 0.61m longer than the Catalina 315. The 1984 Cape Dory 33 displaces approximately 10% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the Catalina 315 has moderate sail power suitable for relaxed cruising with an SA/D ratio of 16.32 and 44.0 m² of sail area. The 1984 Cape Dory 33, with an SA/D of 15.31 and 44.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The Catalina 315 has the edge in terms of raw sailing performance.

For comfort and safety, the Catalina 315 offers a firm, racing-oriented motion (comfort ratio: 18.9) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.77). The 1984 Cape Dory 33 has a comfort ratio of 23.0 and a capsize screening value of 0.73. The ballast ratios are 40.0% for the Catalina 315 and 43.6% for the 1984 Cape Dory 33, reflecting their respective approaches to stability.

Below deck, the Catalina 315 provides 5 berths in 1 cabin with 132L of water capacity and 76L of fuel. The 1984 Cape Dory 33 offers 5 berths in 2 cabins with 151L water and 76L fuel capacity.

Verdict

For cruising: The 1984 Cape Dory 33 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 315 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.
