Detailed Comparison

The 1995 J/80 and 1978 Cape Dory 270 represent two takes on sloop-rigged sailing. The 1995 J/80 is a 1990s design by J/Boats from USA, while the 1978 Cape Dory 270 is a 1970s offering from Cape Dory from USA. The 1995 J/80 was penned by Rod Johnstone. The 1978 Cape Dory 270 was designed by Carl Alberg.

In terms of size, the 1995 J/80 measures 8.00m (26.2ft) overall with a beam of 2.50m, compared to the 1978 Cape Dory 270 at 8.23m (27.0ft) with a 2.59m beam. The 1978 Cape Dory 270 is 0.23m longer than the 1995 J/80. The 1978 Cape Dory 270 displaces approximately 100% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1995 J/80 has generous sail power for spirited sailing with an SA/D ratio of 26.50 and 32.0 m² of sail area. The 1978 Cape Dory 270, with an SA/D of 14.60 and 28.0 m² of canvas, offers modest sail power for its displacement. The 1995 J/80 has the edge in terms of raw sailing performance.

For comfort and safety, the 1995 J/80 offers a firm, racing-oriented motion (comfort ratio: 11.6) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.90). The 1978 Cape Dory 270 has a comfort ratio of 24.4 and a capsize screening value of 0.74. The ballast ratios are 36.7% for the 1995 J/80 and 41.7% for the 1978 Cape Dory 270, reflecting their respective approaches to stability.

Below deck, the 1995 J/80 provides 2 berths with unspecified water tankage and unspecified fuel capacity. The 1978 Cape Dory 270 offers 4 berths in 1 cabin with 68L water and 38L fuel capacity.

Verdict

For cruising: The 1978 Cape Dory 270 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 1995 J/80 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: The 1978 Cape Dory 270 offers more sleeping accommodation, making it better suited for extended living aboard. Consider water and fuel capacity for extended stays away from marinas.
