Detailed Comparison

The 1977 Westerly Centaur and Beneteau First 27 represent two takes on sloop-rigged sailing. The 1977 Westerly Centaur is a 1970s design by Westerly from UK, while the Beneteau First 27 is a 1990s offering from Beneteau from France. The 1977 Westerly Centaur was penned by Laurent Giles. The Beneteau First 27 was designed by Jean Berret.

In terms of size, the 1977 Westerly Centaur measures 7.92m (26.0ft) overall with a beam of 2.69m, compared to the Beneteau First 27 at 8.19m (26.9ft) with a 2.79m beam. The Beneteau First 27 is 0.27m longer than the 1977 Westerly Centaur. The 1977 Westerly Centaur displaces approximately 13% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1977 Westerly Centaur has modest sail power for its displacement with an SA/D ratio of 14.02 and 26.9 m² of sail area. The Beneteau First 27, with an SA/D of 19.84 and 35.0 m² of canvas, offers good sail power for versatile performance. The Beneteau First 27 has the edge in terms of raw sailing performance.

For comfort and safety, the 1977 Westerly Centaur offers a moderate motion comfort level (comfort ratio: 23.8) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.77). The Beneteau First 27 has a comfort ratio of 16.7 and a capsize screening value of 0.83. The ballast ratios are 40.0% for the 1977 Westerly Centaur and 35.4% for the Beneteau First 27, reflecting their respective approaches to stability.

Below deck, the 1977 Westerly Centaur provides 5 berths in 2 cabins with 68L of water capacity and 45L of fuel. The Beneteau First 27 offers 5 berths in 1 cabin with 70L water and 40L fuel capacity.

Verdict

For cruising: The 1977 Westerly Centaur 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 Beneteau First 27 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.
