Coast 34 vs Tartan 34-2: the short version
- The Coast 34 and Tartan 34-2 are close in length (34.3 ft10.46 m vs 34.4 ft10.49 m ).
- The Coast 34 is heavier, displacing about 43% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Tartan 34-2 carries the more powerful rig (17.4 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 Coast 34 rates better for offshore work (1.83 vs 1.97).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
