The Dufour 32 Classic is 0.56m longer than the 1984 O'Day 30. The Dufour 32 Classic displaces approximately 24% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the Dufour 32 Classic has moderate sail power suitable for relaxed cruising with an SA/D ratio of 16.78 and 45.0 m² of sail area. The 1984 O'Day 30, with an SA/D of 15.49 and 36.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The Dufour 32 Classic has the edge in terms of raw sailing performance.

For comfort and safety, the Dufour 32 Classic offers a firm, racing-oriented motion (comfort ratio: 19.0) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.78). The 1984 O'Day 30 has a comfort ratio of 19.4 and a capsize screening value of 0.79. The ballast ratios are 31.1% for the Dufour 32 Classic and 40.0% for the 1984 O'Day 30, reflecting their respective approaches to stability.

Below deck, the Dufour 32 Classic provides 6 berths in 2 cabins with 150L of water capacity and 80L of fuel. The 1984 O'Day 30 offers 6 berths in 2 cabins with 76L water and 57L fuel capacity.

Verdict

For cruising: The 1984 O'Day 30 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 32 Classic 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.
