Detailed Comparison

The 1972 Contest 31 and 1984 Cape Dory 33 represent two takes on sloop-rigged sailing. The 1972 Contest 31 is a 1970s design by Contest from Netherlands, while the 1984 Cape Dory 33 is a 1980s offering from Cape Dory from USA. The 1972 Contest 31 was penned by Dick Zaal. The 1984 Cape Dory 33 was designed by Carl Alberg.

In terms of size, the 1972 Contest 31 measures 9.45m (31.0ft) overall with a beam of 3.05m, 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 1972 Contest 31. 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 1972 Contest 31 has modest sail power for its displacement with an SA/D ratio of 14.65 and 39.5 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 1984 Cape Dory 33 has the edge in terms of raw sailing performance.

For comfort and safety, the 1972 Contest 31 offers a moderate motion comfort level (comfort ratio: 23.7) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.74). 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 1972 Contest 31 and 43.6% for the 1984 Cape Dory 33, reflecting their respective approaches to stability.

Below deck, the 1972 Contest 31 provides 5 berths in 2 cabins with 150L of water capacity and 80L of fuel. The 1984 Cape Dory 33 offers 5 berths in 2 cabins with 151L water and 76L 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 1984 Cape Dory 33 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.
