Detailed Comparison

The 1977 Westerly Centaur and Hanse 315 represent two takes on sloop-rigged sailing. The 1977 Westerly Centaur is a 1970s design by Westerly from UK, while the Hanse 315 is a modern offering from Hanse from Germany. The 1977 Westerly Centaur was penned by Laurent Giles. The Hanse 315 was designed by judel/vrolijk & co.

In terms of size, the 1977 Westerly Centaur measures 7.92m (26.0ft) overall with a beam of 2.69m, compared to the Hanse 315 at 9.65m (31.7ft) with a 3.15m beam. The Hanse 315 is 1.73m longer than the 1977 Westerly Centaur. The Hanse 315 displaces approximately 54% 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 Hanse 315, with an SA/D of 16.20 and 41.5 m² of canvas, offers moderate sail power suitable for relaxed cruising. The Hanse 315 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 Hanse 315 has a comfort ratio of 17.8 and a capsize screening value of 0.78. The ballast ratios are 40.0% for the 1977 Westerly Centaur and 28.6% for the Hanse 315, 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 Hanse 315 offers 4 berths in 1 cabin with 120L water and 85L 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 Hanse 315 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The 1977 Westerly Centaur offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
