Detailed Comparison

The 2015 Hanse 345 and 1983 Pearson 31 represent two takes on sloop-rigged sailing. The 2015 Hanse 345 is a modern design by Hanse from Germany, while the 1983 Pearson 31 is a 1980s offering from Pearson from USA. The 2015 Hanse 345 was penned by Judel/Vrolijk. The 1983 Pearson 31 was designed by William Shaw.

In terms of size, the 2015 Hanse 345 measures 10.37m (34.0ft) overall with a beam of 3.52m, compared to the 1983 Pearson 31 at 9.45m (31.0ft) with a 3.10m beam. The 2015 Hanse 345 is 0.92m longer than the 1983 Pearson 31. The 2015 Hanse 345 displaces approximately 35% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 2015 Hanse 345 has good sail power for versatile performance with an SA/D ratio of 17.47 and 55.5 m² of sail area. The 1983 Pearson 31, with an SA/D of 15.35 and 40.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The 2015 Hanse 345 has the edge in terms of raw sailing performance.

For comfort and safety, the 2015 Hanse 345 offers a firm, racing-oriented motion (comfort ratio: 17.5) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.78). The 1983 Pearson 31 has a comfort ratio of 21.4 and a capsize screening value of 0.76. The ballast ratios are 29.3% for the 2015 Hanse 345 and 42.1% for the 1983 Pearson 31, reflecting their respective approaches to stability.

Below deck, the 2015 Hanse 345 provides 6 berths in 2 cabins with 150L of water capacity and 75L of fuel. The 1983 Pearson 31 offers 6 berths in 2 cabins with 114L water and 68L fuel capacity.

Verdict

For cruising: The 1983 Pearson 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 2015 Hanse 345 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.
