Tartan 33 vs Tartan 34 C: the short version
- The Tartan 34 C is the larger boat at 34.4 ft10.49 m LOA versus 33.7 ft10.26 m for the Tartan 33.
- The Tartan 34 C is heavier, displacing about 12% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Tartan 33 carries the more powerful rig (18.3 vs 16.8), favouring lighter-air performance.
- The Tartan 34 C scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Tartan 34 C rates better for offshore work (1.82 vs 2.03).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
