Performance Comparison
Detailed Comparison
The 1995 J/80 and 1972 Contest 31 represent two takes on sloop-rigged sailing. The 1995 J/80 is a 1990s design by J/Boats from USA, while the 1972 Contest 31 is a 1970s offering from Contest from Netherlands. The 1995 J/80 was penned by Rod Johnstone. The 1972 Contest 31 was designed by Dick Zaal.
In terms of size, the 1995 J/80 measures 8.00m (26.2ft) overall with a beam of 2.50m, compared to the 1972 Contest 31 at 9.45m (31.0ft) with a 3.05m beam. The 1972 Contest 31 is 1.45m longer than the 1995 J/80. The 1972 Contest 31 displaces approximately 234% more than its counterpart, which significantly affects how each boat handles in different sea states.
Looking at performance, the 1995 J/80 has generous sail power for spirited sailing with an SA/D ratio of 26.50 and 32.0 m² of sail area. The 1972 Contest 31, with an SA/D of 14.65 and 39.5 m² of canvas, offers modest sail power for its displacement. The 1995 J/80 has the edge in terms of raw sailing performance.
For comfort and safety, the 1995 J/80 offers a firm, racing-oriented motion (comfort ratio: 11.6) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.90). The 1972 Contest 31 has a comfort ratio of 23.7 and a capsize screening value of 0.74. The ballast ratios are 36.7% for the 1995 J/80 and 40.0% for the 1972 Contest 31, reflecting their respective approaches to stability.
Below deck, the 1995 J/80 provides 2 berths with unspecified water tankage and unspecified fuel capacity. The 1972 Contest 31 offers 5 berths in 2 cabins with 150L water and 80L fuel capacity.
Verdict
For cruising: The 1972 Contest 31 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 1995 J/80 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.
For liveaboard: The 1972 Contest 31 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
