The 1988 Najad 331 was designed by Judel/Vrolijk.

In terms of size, the 1974 Tartan 27 measures 8.23m (27.0ft) overall with a beam of 2.69m, compared to the 1988 Najad 331 at 10.06m (33.0ft) with a 3.18m beam. The 1988 Najad 331 is 1.83m longer than the 1974 Tartan 27. The 1988 Najad 331 displaces approximately 66% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1974 Tartan 27 has moderate sail power suitable for relaxed cruising with an SA/D ratio of 16.56 and 33.5 m² of sail area. The 1988 Najad 331, with an SA/D of 15.15 and 43.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The 1974 Tartan 27 has the edge in terms of raw sailing performance.

For comfort and safety, the 1974 Tartan 27 offers a moderate motion comfort level (comfort ratio: 25.1) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.75). The 1988 Najad 331 has a comfort ratio of 20.4 and a capsize screening value of 0.75. The ballast ratios are 46.2% for the 1974 Tartan 27 and 40.8% for the 1988 Najad 331, reflecting their respective approaches to stability.

Below deck, the 1974 Tartan 27 provides 5 berths in 1 cabin with 57L of water capacity and 38L of fuel. The 1988 Najad 331 offers 5 berths in 2 cabins with 140L water and 80L fuel capacity.

Verdict

For cruising: The 1974 Tartan 27 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 1974 Tartan 27 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.
