Coronado 15 vs Sirocco 15: the short version
- The Coronado 15 and Sirocco 15 are close in length (15.3 ft4.67 m vs 15.3 ft4.67 m ).
- The Sirocco 15 is heavier, displacing about 22% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Coronado 15 carries the more powerful rig (42.0 vs 38.9), favouring lighter-air performance.
- By the capsize screening formula the Sirocco 15 rates better for offshore work (3.05 vs 3.12).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
