Performance Comparison
Detailed Comparison
The 1986 J/28 and 1975 Cal 29 represent two takes on sloop-rigged sailing. The 1986 J/28 is a 1980s design by J/Boats from USA, while the 1975 Cal 29 is a 1970s offering from Cal from USA. The 1986 J/28 was penned by Rod Johnstone. The 1975 Cal 29 was designed by Bill Lapworth.
In terms of size, the 1986 J/28 measures 8.66m (28.4ft) overall with a beam of 3.05m, compared to the 1975 Cal 29 at 8.84m (29.0ft) with a 2.84m beam. The 1975 Cal 29 is 0.18m longer than the 1986 J/28. The 1975 Cal 29 displaces approximately 8% more than its counterpart, which significantly affects how each boat handles in different sea states.
Looking at performance, the 1986 J/28 has good sail power for versatile performance with an SA/D ratio of 18.59 and 37.6 m² of sail area. The 1975 Cal 29, with an SA/D of 15.99 and 34.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The 1986 J/28 has the edge in terms of raw sailing performance.
For comfort and safety, the 1986 J/28 offers a firm, racing-oriented motion (comfort ratio: 17.2) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.85). The 1975 Cal 29 has a comfort ratio of 20.1 and a capsize screening value of 0.77. The ballast ratios are 46.2% for the 1986 J/28 and 42.9% for the 1975 Cal 29, reflecting their respective approaches to stability.
Below deck, the 1986 J/28 provides 5 berths in 1 cabin with 57L of water capacity and 38L of fuel. The 1975 Cal 29 offers 5 berths in 1 cabin with 76L water and 45L fuel capacity.
Verdict
For cruising: The 1975 Cal 29 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 1986 J/28 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.
