Alajuela 33 vs Arco 33: the short version
- The Alajuela 33 and Arco 33 are close in length (33.0 ft10.06 m vs 33.0 ft10.06 m ).
- The Alajuela 33 is heavier, displacing about 13% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Arco 33 carries the more powerful rig (16.8 vs 16.2), favouring lighter-air performance.
- The Arco 33 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Arco 33 rates better for offshore work (1.72 vs 1.79).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
