Detailed Comparison

The 1994 J/105 and 1975 Cal 29 represent two takes on sloop-rigged sailing. The 1994 J/105 is a 1990s design by J/Boats from USA, while the 1975 Cal 29 is a 1970s offering from Cal from USA. The 1994 J/105 was penned by Rod Johnstone. The 1975 Cal 29 was designed by Bill Lapworth.

In terms of size, the 1994 J/105 measures 10.52m (34.5ft) overall with a beam of 3.28m, compared to the 1975 Cal 29 at 8.84m (29.0ft) with a 2.84m beam. The 1994 J/105 is 1.68m longer than the 1975 Cal 29. The 1994 J/105 displaces approximately 21% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1994 J/105 has generous sail power for spirited sailing with an SA/D ratio of 23.80 and 57.6 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 1994 J/105 has the edge in terms of raw sailing performance.

For comfort and safety, the 1994 J/105 offers a firm, racing-oriented motion (comfort ratio: 13.7) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.84). The 1975 Cal 29 has a comfort ratio of 20.1 and a capsize screening value of 0.77. The ballast ratios are 43.5% for the 1994 J/105 and 42.9% for the 1975 Cal 29, reflecting their respective approaches to stability.

Below deck, the 1994 J/105 provides 6 berths in 2 cabins 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 1994 J/105 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The 1994 J/105 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
