F1 vs K2: the short version
- The K2 is the larger boat at 17.0 ft5.18 m LOA versus 15.7 ft4.79 m for the F1.
- The K2 is heavier, displacing about 35% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the K2 carries the more powerful rig (55.9 vs 48.3), favouring lighter-air performance.
- By the capsize screening formula the F1 rates better for offshore work (4.14 vs 4.58).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
