Coast 34 vs Tartan 34 C: the short version
- The Coast 34 and Tartan 34 C are close in length (34.3 ft10.46 m vs 34.4 ft10.49 m ).
- The Coast 34 is heavier, displacing about 41% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Tartan 34 C carries the more powerful rig (16.8 vs 15.9), favouring lighter-air performance.
- The Coast 34 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 1.83).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
