Alacrity 19 vs Sailfish 18: the short version
- The Alacrity 19 and Sailfish 18 are close in length (18.5 ft5.64 m vs 18.5 ft5.65 m ).
- The Alacrity 19 is heavier, displacing about 51% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Sailfish 18 carries the more powerful rig (27.7 vs 19.3), favouring lighter-air performance.
- The Alacrity 19 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Alacrity 19 rates better for offshore work (2.42 vs 2.83).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
