Frigate 36 vs Invader 36: the short version
- The Frigate 36 and Invader 36 are close in length (35.7 ft10.87 m vs 35.8 ft10.90 m ).
- The Frigate 36 is heavier, displacing about 10% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Invader 36 carries the more powerful rig (16.8 vs 16.0), favouring lighter-air performance.
- The Invader 36 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Invader 36 rates better for offshore work (1.67 vs 1.80).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
