Performance Comparison
Detailed Comparison
The 1990 Dehler 31 and 1977 Cal 33 represent two takes on sloop-rigged sailing. The 1990 Dehler 31 is a 1990s design by Dehler from Germany, while the 1977 Cal 33 is a 1970s offering from Cal from USA. The 1990 Dehler 31 was penned by Judel/Vrolijk. The 1977 Cal 33 was designed by Bill Lapworth / C. Raymond Hunt.
In terms of size, the 1990 Dehler 31 measures 9.45m (31.0ft) overall with a beam of 3.13m, compared to the 1977 Cal 33 at 10.06m (33.0ft) with a 3.20m beam. The 1977 Cal 33 is 0.61m longer than the 1990 Dehler 31. The 1977 Cal 33 displaces approximately 34% more than its counterpart, which significantly affects how each boat handles in different sea states.
Looking at performance, the 1990 Dehler 31 has good sail power for versatile performance with an SA/D ratio of 18.05 and 44.0 m² of sail area. The 1977 Cal 33, with an SA/D of 14.53 and 43.0 m² of canvas, offers modest sail power for its displacement. The 1990 Dehler 31 has the edge in terms of raw sailing performance.
For comfort and safety, the 1990 Dehler 31 offers a firm, racing-oriented motion (comfort ratio: 18.2) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.80). The 1977 Cal 33 has a comfort ratio of 22.6 and a capsize screening value of 0.74. The ballast ratios are 40.0% for the 1990 Dehler 31 and 41.7% for the 1977 Cal 33, reflecting their respective approaches to stability.
Below deck, the 1990 Dehler 31 provides 5 berths in 2 cabins with 100L of water capacity and 60L of fuel. The 1977 Cal 33 offers 6 berths in 2 cabins with 114L water and 68L fuel capacity.
Verdict
For cruising: The 1977 Cal 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 1990 Dehler 31 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.
For liveaboard: The 1977 Cal 33 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
