Detailed Comparison

The 1991 Westerly Seahawk and 1975 Pearson 28 represent two takes on sloop-rigged sailing. The 1991 Westerly Seahawk is a 1990s design by Westerly from UK, while the 1975 Pearson 28 is a 1970s offering from Pearson from USA. The 1991 Westerly Seahawk was penned by Ed Dubois. The 1975 Pearson 28 was designed by William Shaw.

In terms of size, the 1991 Westerly Seahawk measures 10.36m (34.0ft) overall with a beam of 3.35m, compared to the 1975 Pearson 28 at 8.53m (28.0ft) with a 2.74m beam. The 1991 Westerly Seahawk is 1.83m longer than the 1975 Pearson 28. The 1991 Westerly Seahawk displaces approximately 108% 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 1975 Pearson 28, with an SA/D of 14.83 and 30.0 m² of canvas, offers modest sail power for its displacement. The 1975 Pearson 28 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 1975 Pearson 28 has a comfort ratio of 21.2 and a capsize screening value of 0.77. The ballast ratios are 40.8% for the 1991 Westerly Seahawk and 43.1% for the 1975 Pearson 28, 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 1975 Pearson 28 offers 5 berths in 1 cabin with 57L water and 38L 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 1975 Pearson 28 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.
