The 1991 Westerly Seahawk displaces approximately 12% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1991 Westerly Seahawk has modest sail power for its displacement with an SA/D ratio of 14.57 and 48.0 m² of sail area. The 1984 Pearson 34, with an SA/D of 15.11 and 46.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The 1984 Pearson 34 has the edge in terms of raw sailing performance.

For comfort and safety, the 1991 Westerly Seahawk offers a moderate motion comfort level (comfort ratio: 22.8) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.73). The 1984 Pearson 34 has a comfort ratio of 20.3 and a capsize screening value of 0.76. The ballast ratios are 40.8% for the 1991 Westerly Seahawk and 41.7% for the 1984 Pearson 34, reflecting their respective approaches to stability.

Below deck, the 1991 Westerly Seahawk provides 7 berths in 3 cabins with 220L of water capacity and 114L of fuel. The 1984 Pearson 34 offers 6 berths in 2 cabins with 152L water and 76L fuel capacity.

Verdict

For cruising: The 1991 Westerly Seahawk 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 1984 Pearson 34 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The 1991 Westerly Seahawk offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
