Detailed Comparison

The 1969 Cal 34 and 1975 Pearson 28 represent two takes on sloop-rigged sailing. The 1969 Cal 34 is a classic design by Cal from USA, while the 1975 Pearson 28 is a 1970s offering from Pearson from USA. The 1969 Cal 34 was penned by Bill Lapworth. The 1975 Pearson 28 was designed by William Shaw.

In terms of size, the 1969 Cal 34 measures 10.36m (34.0ft) overall with a beam of 3.05m, compared to the 1975 Pearson 28 at 8.53m (28.0ft) with a 2.74m beam. The 1969 Cal 34 is 1.83m longer than the 1975 Pearson 28. The 1969 Cal 34 displaces approximately 77% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1969 Cal 34 has moderate sail power suitable for relaxed cruising with an SA/D ratio of 16.01 and 47.4 m² of sail area. The 1975 Pearson 28, with an SA/D of 14.83 and 30.0 m² of canvas, offers modest sail power for its displacement. The 1969 Cal 34 has the edge in terms of raw sailing performance.

For comfort and safety, the 1969 Cal 34 offers a moderate motion comfort level (comfort ratio: 23.6) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.70). The 1975 Pearson 28 has a comfort ratio of 21.2 and a capsize screening value of 0.77. The ballast ratios are 39.1% for the 1969 Cal 34 and 43.1% for the 1975 Pearson 28, reflecting their respective approaches to stability.

Below deck, the 1969 Cal 34 provides 6 berths in 2 cabins with 114L of water capacity and 57L of fuel. The 1975 Pearson 28 offers 5 berths in 1 cabin with 57L water and 38L fuel capacity.

Verdict

For cruising: The 1969 Cal 34 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 1969 Cal 34 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The 1969 Cal 34 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
