Impulse vs RS Aero: the short version
- The Impulse and RS Aero are close in length (13.1 ft4.00 m vs 13.2 ft4.01 m ).
- The Impulse is heavier, displacing about 58% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Impulse carries the more powerful rig (60.0 vs 4.9), favouring lighter-air performance.
- By the capsize screening formula the Impulse rates better for offshore work (4.20 vs 4.54).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
