For comfort and safety, the Dufour 470 offers a firm, racing-oriented motion (comfort ratio: 13.7) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.79). The 2013 Oyster 485 has a comfort ratio of 17.1 and a capsize screening value of 0.72. The ballast ratios are 31.3% for the Dufour 470 and 38.0% for the 2013 Oyster 485, reflecting their respective approaches to stability.

Below deck, the Dufour 470 provides 10 berths in 4 cabins with 440L of water capacity and 220L of fuel. The 2013 Oyster 485 offers 7 berths in 3 cabins with 550L water and 300L fuel capacity.

Verdict

For cruising: The 2013 Oyster 485 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 470 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 470 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
