Alpha 100 SL vs Custom Windski Speed: the short version
- The Alpha 100 SL and Custom Windski Speed are close in length (9.0 ft2.75 m vs 9.2 ft2.80 m ).
- The Alpha 100 SL is heavier, displacing about 33% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the Alpha 100 SL rates better for offshore work (2.90 vs 2.98).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
