Detailed Comparison

The 1979 Peterson 44 and Dufour 40 represent two takes on sloop-rigged sailing. The 1979 Peterson 44 is a 1970s design by Peterson from USA, while the Dufour 40 is a 2000s offering from Dufour from France. The 1979 Peterson 44 was penned by Doug Peterson. The Dufour 40 was designed by Umberto Felci.

In terms of size, the 1979 Peterson 44 measures 13.41m (44.0ft) overall with a beam of 3.86m, compared to the Dufour 40 at 12.05m (39.5ft) with a 3.85m beam. The 1979 Peterson 44 is 1.36m longer than the Dufour 40. The 1979 Peterson 44 displaces approximately 28% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1979 Peterson 44 has good sail power for versatile performance with an SA/D ratio of 17.31 and 79.0 m² of sail area. The Dufour 40, with an SA/D of 17.56 and 68.0 m² of canvas, offers good sail power for versatile performance. The Dufour 40 has the edge in terms of raw sailing performance.

For comfort and safety, the 1979 Peterson 44 offers a firm, racing-oriented motion (comfort ratio: 19.2) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.72). The Dufour 40 has a comfort ratio of 16.4 and a capsize screening value of 0.78. The ballast ratios are 40.9% for the 1979 Peterson 44 and 30.8% for the Dufour 40, reflecting their respective approaches to stability.

Below deck, the 1979 Peterson 44 provides 7 berths in 3 cabins with 265L of water capacity and 151L of fuel. The Dufour 40 offers 8 berths in 3 cabins with 300L water and 160L fuel capacity.

Verdict

For cruising: The 1979 Peterson 44 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 Dufour 40 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The Dufour 40 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
