Detailed Comparison

The 1975 S2 9.2C and 1983 Irwin 32 represent two takes on sloop-rigged sailing. The 1975 S2 9.2C is a 1970s design by S2 from USA, while the 1983 Irwin 32 is a 1980s offering from Irwin from USA. The 1975 S2 9.2C was penned by Arthur Edmunds. The 1983 Irwin 32 was designed by Ted Irwin.

In terms of size, the 1975 S2 9.2C measures 9.14m (30.0ft) overall with a beam of 3.05m, compared to the 1983 Irwin 32 at 9.75m (32.0ft) with a 3.20m beam. The 1983 Irwin 32 is 0.61m longer than the 1975 S2 9.2C. The 1983 Irwin 32 displaces approximately 22% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1975 S2 9.2C has moderate sail power suitable for relaxed cruising with an SA/D ratio of 16.99 and 42.7 m² of sail area. The 1983 Irwin 32, with an SA/D of 14.27 and 41.0 m² of canvas, offers modest sail power for its displacement. The 1975 S2 9.2C has the edge in terms of raw sailing performance.

For comfort and safety, the 1975 S2 9.2C offers a moderate motion comfort level (comfort ratio: 21.8) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.76). The 1983 Irwin 32 has a comfort ratio of 22.1 and a capsize screening value of 0.75. The ballast ratios are 41.1% for the 1975 S2 9.2C and 40.9% for the 1983 Irwin 32, reflecting their respective approaches to stability.

Below deck, the 1975 S2 9.2C provides 6 berths in 1 cabin with 76L of water capacity and 57L of fuel. The 1983 Irwin 32 offers 6 berths in 2 cabins with 114L water and 68L fuel capacity.

Verdict

For cruising: The 1983 Irwin 32 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 1975 S2 9.2C 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.
