The 1990 J/40 is 1.40m longer than the Dufour 36 Classic. The 1990 J/40 displaces approximately 24% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1990 J/40 has good sail power for versatile performance with an SA/D ratio of 18.87 and 72.5 m² of sail area. The Dufour 36 Classic, with an SA/D of 17.16 and 57.0 m² of canvas, offers good sail power for versatile performance. The 1990 J/40 has the edge in terms of raw sailing performance.

For comfort and safety, the 1990 J/40 offers a firm, racing-oriented motion (comfort ratio: 18.0) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.74). The Dufour 36 Classic has a comfort ratio of 18.0 and a capsize screening value of 0.76. The ballast ratios are 44.1% for the 1990 J/40 and 32.3% for the Dufour 36 Classic, reflecting their respective approaches to stability.

Below deck, the 1990 J/40 provides 6 berths in 2 cabins with 189L of water capacity and 114L of fuel. The Dufour 36 Classic offers 6 berths in 2 cabins with 200L water and 110L fuel capacity.

Verdict

For cruising: The Dufour 36 Classic 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 1990 J/40 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.
