Detailed Comparison

The Catalina 315 and 2005 Dehler 34 represent two takes on sloop-rigged sailing. The Catalina 315 is a modern design by Catalina from USA, while the 2005 Dehler 34 is a 2000s offering from Dehler from Germany. The Catalina 315 was penned by Gerry Douglas. The 2005 Dehler 34 was designed by Judel/Vrolijk.

In terms of size, the Catalina 315 measures 9.45m (31.0ft) overall with a beam of 3.20m, compared to the 2005 Dehler 34 at 10.30m (33.8ft) with a 3.25m beam. The 2005 Dehler 34 is 0.85m longer than the Catalina 315. The 2005 Dehler 34 displaces approximately 6% 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 2005 Dehler 34, with an SA/D of 17.85 and 50.0 m² of canvas, offers good sail power for versatile performance. The 2005 Dehler 34 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 2005 Dehler 34 has a comfort ratio of 17.2 and a capsize screening value of 0.77. The ballast ratios are 40.0% for the Catalina 315 and 35.4% for the 2005 Dehler 34, 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 2005 Dehler 34 offers 6 berths in 2 cabins with 100L water and 50L fuel capacity.

Verdict

For cruising: The Catalina 315 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 2005 Dehler 34 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The 2005 Dehler 34 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
