In terms of size, the 1975 Pearson 39 measures 11.89m (39.0ft) overall with a beam of 3.51m, compared to the 2005 Dehler 34 at 10.30m (33.8ft) with a 3.25m beam. The 1975 Pearson 39 is 1.59m longer than the 2005 Dehler 34. The 1975 Pearson 39 displaces approximately 61% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1975 Pearson 39 has moderate sail power suitable for relaxed cruising with an SA/D ratio of 15.83 and 60.8 m² of sail area. The 2005 Dehler 34, with an SA/D of 17.85 and 50.0 m² of canvas, offers good sail power for versatile performance. The 2005 Dehler 34 has the edge in terms of raw sailing performance.

For comfort and safety, the 1975 Pearson 39 offers a moderate motion comfort level (comfort ratio: 21.5) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.71). The 2005 Dehler 34 has a comfort ratio of 17.2 and a capsize screening value of 0.77. The ballast ratios are 41.2% for the 1975 Pearson 39 and 35.4% for the 2005 Dehler 34, reflecting their respective approaches to stability.

Below deck, the 1975 Pearson 39 provides 7 berths in 2 cabins with 189L of water capacity and 114L of fuel. The 2005 Dehler 34 offers 6 berths in 2 cabins with 100L water and 50L fuel capacity.

Verdict

For cruising: The 1975 Pearson 39 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: The 1975 Pearson 39 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
