Detailed Comparison

The 1984 J/29 and 1990 Island Packet 29 represent two takes on sloop-rigged sailing. The 1984 J/29 is a 1980s design by J/Boats from USA, while the 1990 Island Packet 29 is a 1990s offering from Island Packet from USA. The 1984 J/29 was penned by Rod Johnstone. The 1990 Island Packet 29 was designed by Bob Johnson.

In terms of size, the 1984 J/29 measures 8.99m (29.5ft) overall with a beam of 3.28m, compared to the 1990 Island Packet 29 at 8.84m (29.0ft) with a 3.05m beam. The 1984 J/29 is 0.15m longer than the 1990 Island Packet 29. The 1990 Island Packet 29 displaces approximately 18% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1984 J/29 has good sail power for versatile performance with an SA/D ratio of 18.97 and 41.1 m² of sail area. The 1990 Island Packet 29, with an SA/D of 13.84 and 33.5 m² of canvas, offers modest sail power for its displacement. The 1984 J/29 has the edge in terms of raw sailing performance.

For comfort and safety, the 1984 J/29 offers a firm, racing-oriented motion (comfort ratio: 16.0) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.89). The 1990 Island Packet 29 has a comfort ratio of 21.6 and a capsize screening value of 0.78. The ballast ratios are 45.8% for the 1984 J/29 and 41.2% for the 1990 Island Packet 29, reflecting their respective approaches to stability.

Below deck, the 1984 J/29 provides 5 berths in 1 cabin with 38L of water capacity and 38L of fuel. The 1990 Island Packet 29 offers 5 berths in 1 cabin with 132L water and 76L fuel capacity.

Verdict

For cruising: The 1990 Island Packet 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 1984 J/29 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.
