The 1991 Westerly Seahawk was designed by Ed Dubois.

In terms of size, the 1984 J/29 measures 8.99m (29.5ft) overall with a beam of 3.28m, compared to the 1991 Westerly Seahawk at 10.36m (34.0ft) with a 3.35m beam. The 1991 Westerly Seahawk is 1.37m longer than the 1984 J/29. The 1991 Westerly Seahawk displaces approximately 87% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1984 J/29 has good sail power for versatile performance with an SA/D ratio of 18.97 and 41.1 m² of sail area. The 1991 Westerly Seahawk, with an SA/D of 14.57 and 48.0 m² of canvas, offers modest sail power for its displacement. The 1984 J/29 has the edge in terms of raw sailing performance.

For comfort and safety, the 1984 J/29 offers a firm, racing-oriented motion (comfort ratio: 16.0) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.89). The 1991 Westerly Seahawk has a comfort ratio of 22.8 and a capsize screening value of 0.73. The ballast ratios are 45.8% for the 1984 J/29 and 40.8% for the 1991 Westerly Seahawk, reflecting their respective approaches to stability.

Below deck, the 1984 J/29 provides 5 berths in 1 cabin with 38L of water capacity and 38L of fuel. The 1991 Westerly Seahawk offers 7 berths in 3 cabins with 220L water and 114L 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 J/29 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.
