Detailed Comparison

The Catalina 315 and 1979 Westerly Fulmar represent two takes on sloop-rigged sailing. The Catalina 315 is a modern design by Catalina from USA, while the 1979 Westerly Fulmar is a 1970s offering from Westerly from UK. The Catalina 315 was penned by Gerry Douglas. The 1979 Westerly Fulmar was designed by Ed Dubois.

In terms of size, the Catalina 315 measures 9.45m (31.0ft) overall with a beam of 3.20m, compared to the 1979 Westerly Fulmar at 9.75m (32.0ft) with a 3.20m beam. The 1979 Westerly Fulmar is 0.30m longer than the Catalina 315. The 1979 Westerly Fulmar 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 1979 Westerly Fulmar, with an SA/D of 12.53 and 36.0 m² of canvas, offers modest sail power for its displacement. 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 1979 Westerly Fulmar has a comfort ratio of 22.4 and a capsize screening value of 0.75. The ballast ratios are 40.0% for the Catalina 315 and 36.4% for the 1979 Westerly Fulmar, 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 1979 Westerly Fulmar offers 6 berths in 2 cabins with 136L water and 68L fuel capacity.

Verdict

For cruising: The 1979 Westerly Fulmar 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: The 1979 Westerly Fulmar offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
