Detailed Comparison

The 1972 Contest 31 and 1990 Island Packet 29 represent two takes on sloop-rigged sailing. The 1972 Contest 31 is a 1970s design by Contest from Netherlands, while the 1990 Island Packet 29 is a 1990s offering from Island Packet from USA. The 1972 Contest 31 was penned by Dick Zaal. The 1990 Island Packet 29 was designed by Bob Johnson.

In terms of size, the 1972 Contest 31 measures 9.45m (31.0ft) overall with a beam of 3.05m, compared to the 1990 Island Packet 29 at 8.84m (29.0ft) with a 3.05m beam. The 1972 Contest 31 is 0.61m longer than the 1990 Island Packet 29. The 1972 Contest 31 displaces approximately 18% 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 1990 Island Packet 29, with an SA/D of 13.84 and 33.5 m² of canvas, offers modest sail power for its displacement. The 1972 Contest 31 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 1990 Island Packet 29 has a comfort ratio of 21.6 and a capsize screening value of 0.78. The ballast ratios are 40.0% for the 1972 Contest 31 and 41.2% for the 1990 Island Packet 29, 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 1990 Island Packet 29 offers 5 berths in 1 cabin with 132L 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 1972 Contest 31 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.
