Alpha 165 F vs Surf Catamaran 330: the short version
- The Alpha 165 F and Surf Catamaran 330 are close in length (10.8 ft3.30 m vs 10.8 ft3.30 m ).
- The Surf Catamaran 330 is heavier, displacing about 36% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the Alpha 165 F rates better for offshore work (2.97 vs 3.98).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
