Detailed Comparison

The 1965 Pearson Vanguard and 1983 Irwin 32 represent two takes on sloop-rigged sailing. The 1965 Pearson Vanguard is a classic design by Pearson from USA, while the 1983 Irwin 32 is a 1980s offering from Irwin from USA. The 1965 Pearson Vanguard was penned by Philip Rhodes. The 1983 Irwin 32 was designed by Ted Irwin.

In terms of size, the 1965 Pearson Vanguard measures 9.83m (32.3ft) overall with a beam of 2.84m, compared to the 1983 Irwin 32 at 9.75m (32.0ft) with a 3.20m beam. The 1965 Pearson Vanguard is 0.08m longer than the 1983 Irwin 32. The 1983 Irwin 32 displaces approximately 22% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1965 Pearson Vanguard has modest sail power for its displacement with an SA/D ratio of 14.32 and 36.0 m² of sail area. The 1983 Irwin 32, with an SA/D of 14.27 and 41.0 m² of canvas, offers modest sail power for its displacement. The 1965 Pearson Vanguard has the edge in terms of raw sailing performance.

For comfort and safety, the 1965 Pearson Vanguard offers a moderate motion comfort level (comfort ratio: 25.3) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.71). The 1983 Irwin 32 has a comfort ratio of 22.1 and a capsize screening value of 0.75. The ballast ratios are 41.1% for the 1965 Pearson Vanguard and 40.9% for the 1983 Irwin 32, reflecting their respective approaches to stability.

Below deck, the 1965 Pearson Vanguard provides 5 berths in 1 cabin with 57L of water capacity and 38L of fuel. The 1983 Irwin 32 offers 6 berths in 2 cabins with 114L water and 68L fuel capacity.

Verdict

For cruising: The 1965 Pearson Vanguard 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 1965 Pearson Vanguard has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The 1983 Irwin 32 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
