Detailed Comparison

The 1979 Westsail 43 and 1985 Irwin 52 represent two takes on ketch-rigged sailing. The 1979 Westsail 43 is a 1970s design by Westsail from USA, while the 1985 Irwin 52 is a 1980s offering from Irwin from USA. The 1979 Westsail 43 was penned by William Crealock. The 1985 Irwin 52 was designed by Ted Irwin.

In terms of size, the 1979 Westsail 43 measures 13.11m (43.0ft) overall with a beam of 3.96m, compared to the 1985 Irwin 52 at 15.85m (52.0ft) with a 4.42m beam. The 1985 Irwin 52 is 2.74m longer than the 1979 Westsail 43. The 1985 Irwin 52 displaces approximately 19% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1979 Westsail 43 has modest sail power for its displacement with an SA/D ratio of 13.31 and 78.0 m² of sail area. The 1985 Irwin 52, with an SA/D of 15.83 and 104.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The 1985 Irwin 52 has the edge in terms of raw sailing performance.

For comfort and safety, the 1979 Westsail 43 offers a moderate motion comfort level (comfort ratio: 27.4) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.65). The 1985 Irwin 52 has a comfort ratio of 20.1 and a capsize screening value of 0.69. The ballast ratios are 40.6% for the 1979 Westsail 43 and 36.8% for the 1985 Irwin 52, reflecting their respective approaches to stability.

Below deck, the 1979 Westsail 43 provides 8 berths in 3 cabins with 568L of water capacity and 284L of fuel. The 1985 Irwin 52 offers 8 berths in 3 cabins with 568L water and 340L fuel capacity.

Verdict

For cruising: The 1979 Westsail 43 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 1985 Irwin 52 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.
