470 vs Coronado 15: the short version
- The 470 and Coronado 15 are close in length (15.4 ft4.70 m vs 15.3 ft4.67 m ).
- The Coronado 15 is heavier, displacing about 45% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the 470 carries the more powerful rig (53.1 vs 42.0), favouring lighter-air performance.
- By the capsize screening formula the 470 rates better for offshore work (2.60 vs 3.12).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
