Detailed Comparison

The 1977 Westerly Centaur and 1990 Island Packet 29 represent two takes on sloop-rigged sailing. The 1977 Westerly Centaur is a 1970s design by Westerly from UK, while the 1990 Island Packet 29 is a 1990s offering from Island Packet from USA. The 1977 Westerly Centaur was penned by Laurent Giles. The 1990 Island Packet 29 was designed by Bob Johnson.

In terms of size, the 1977 Westerly Centaur measures 7.92m (26.0ft) overall with a beam of 2.69m, compared to the 1990 Island Packet 29 at 8.84m (29.0ft) with a 3.05m beam. The 1990 Island Packet 29 is 0.92m longer than the 1977 Westerly Centaur. The 1990 Island Packet 29 displaces approximately 42% 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 1990 Island Packet 29, with an SA/D of 13.84 and 33.5 m² of canvas, offers modest sail power for its displacement. The 1977 Westerly Centaur 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 1990 Island Packet 29 has a comfort ratio of 21.6 and a capsize screening value of 0.78. The ballast ratios are 40.0% for the 1977 Westerly Centaur and 41.2% for the 1990 Island Packet 29, 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 1990 Island Packet 29 offers 5 berths in 1 cabin with 132L water and 76L 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 1977 Westerly Centaur 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.
