Detailed Comparison

The 1986 J/28 and 1984 Dehler 25 represent two takes on sloop-rigged sailing. The 1986 J/28 is a 1980s design by J/Boats from USA, while the 1984 Dehler 25 is a 1980s offering from Dehler from Germany. The 1986 J/28 was penned by Rod Johnstone. The 1984 Dehler 25 was designed by E.G. van de Stadt.

In terms of size, the 1986 J/28 measures 8.66m (28.4ft) overall with a beam of 3.05m, compared to the 1984 Dehler 25 at 7.50m (24.6ft) with a 2.50m beam. The 1986 J/28 is 1.16m longer than the 1984 Dehler 25. The 1986 J/28 displaces approximately 64% 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 1984 Dehler 25, with an SA/D of 15.46 and 22.5 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 1984 Dehler 25 has a comfort ratio of 18.4 and a capsize screening value of 0.82. The ballast ratios are 46.2% for the 1986 J/28 and 37.8% for the 1984 Dehler 25, 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 1984 Dehler 25 offers 4 berths in 1 cabin with 40L water and 25L fuel capacity.

Verdict

For cruising: The 1984 Dehler 25 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: The 1986 J/28 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
