The 1987 Cape Dory 40 has a comfort ratio of 22.3 and a capsize screening value of 0.72. The ballast ratios are 30.8% for the Dufour 40 and 42.1% for the 1987 Cape Dory 40, reflecting their respective approaches to stability.

Below deck, the Dufour 40 provides 8 berths in 3 cabins with 300L of water capacity and 160L of fuel. The 1987 Cape Dory 40 offers 7 berths in 2 cabins with 284L water and 151L fuel capacity.

Verdict

For cruising: The 1987 Cape Dory 40 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.
