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 2005 Dehler 34 has the edge in terms of raw sailing performance.

For comfort and safety, the 2005 Dehler 34 offers a firm, racing-oriented motion (comfort ratio: 17.2) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.77). The 1983 Irwin 32 has a comfort ratio of 22.1 and a capsize screening value of 0.75. The ballast ratios are 35.4% for the 2005 Dehler 34 and 40.9% for the 1983 Irwin 32, reflecting their respective approaches to stability.

Below deck, the 2005 Dehler 34 provides 6 berths in 2 cabins with 100L of water capacity and 50L 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 2005 Dehler 34 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.
