F1 vs Spitfire 2.3: the short version
- The Spitfire 2.3 is the larger boat at 18.0 ft5.49 m LOA versus 15.7 ft4.79 m for the F1.
- The Spitfire 2.3 is heavier, displacing about 56% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Spitfire 2.3 carries the more powerful rig (53.3 vs 48.3), favouring lighter-air performance.
- By the capsize screening formula the F1 rates better for offshore work (4.14 vs 4.46).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
