Alpha 120 F vs Shrimp: the short version
- The Alpha 120 F and Shrimp are close in length (9.7 ft2.95 m vs 9.6 ft2.92 m ).
- The Shrimp is heavier, displacing about 380% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the Alpha 120 F rates better for offshore work (2.83 vs 3.92).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
