Detailed Comparison

The 1973 Tartan 34 and 1974 Morgan 33 represent two takes on sloop-rigged sailing. The 1973 Tartan 34 is a 1970s design by Tartan from USA, while the 1974 Morgan 33 is a 1970s offering from Morgan from USA. The 1973 Tartan 34 was penned by Sparkman & Stephens. The 1974 Morgan 33 was designed by Charlie Morgan.

In terms of size, the 1973 Tartan 34 measures 10.36m (34.0ft) overall with a beam of 3.05m, compared to the 1974 Morgan 33 at 10.06m (33.0ft) with a 3.20m beam. The 1973 Tartan 34 is 0.30m longer than the 1974 Morgan 33. The 1973 Tartan 34 displaces approximately 4% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1973 Tartan 34 has moderate sail power suitable for relaxed cruising with an SA/D ratio of 15.27 and 46.5 m² of sail area. The 1974 Morgan 33, with an SA/D of 14.19 and 42.0 m² of canvas, offers modest sail power for its displacement. The 1973 Tartan 34 has the edge in terms of raw sailing performance.

For comfort and safety, the 1973 Tartan 34 offers a moderate motion comfort level (comfort ratio: 27.3) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.69). The 1974 Morgan 33 has a comfort ratio of 22.1 and a capsize screening value of 0.74. The ballast ratios are 45.0% for the 1973 Tartan 34 and 39.1% for the 1974 Morgan 33, reflecting their respective approaches to stability.

Below deck, the 1973 Tartan 34 provides 6 berths in 2 cabins with 114L of water capacity and 76L of fuel. The 1974 Morgan 33 offers 6 berths in 2 cabins with 114L water and 76L fuel capacity.

Verdict

For cruising: The 1973 Tartan 34 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 1973 Tartan 34 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.
