Coronado 15 vs US1: the short version
- The Coronado 15 and US1 are close in length (15.3 ft4.67 m vs 15.4 ft4.70 m ).
- The Coronado 15 is heavier, displacing about 103% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the US1 carries the more powerful rig (43.6 vs 42.0), favouring lighter-air performance.
- By the capsize screening formula the Coronado 15 rates better for offshore work (3.12 vs 3.19).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
