The 1983 Irwin 32 has a comfort ratio of 22.1 and a capsize screening value of 0.75. The ballast ratios are 42.1% for the 1983 Pearson 31 and 40.9% for the 1983 Irwin 32, reflecting their respective approaches to stability.
Below deck, the 1983 Pearson 31 provides 6 berths in 2 cabins with 114L of water capacity and 68L 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 1983 Pearson 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.
