Niagara 26 vs Seaward 25: the short version
- The Niagara 26 and Seaward 25 are close in length (26.7 ft8.13 m vs 26.8 ft8.15 m ).
- The Niagara 26 is heavier, displacing about 11% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Niagara 26 carries the more powerful rig (20.1 vs 16.8), favouring lighter-air performance.
- The Niagara 26 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Niagara 26 rates better for offshore work (2.10 vs 2.17).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
