JY15 vs Precision 15: the short version
- The JY15 and Precision 15 are close in length (15.0 ft4.57 m vs 15.0 ft4.57 m ).
- The Precision 15 is heavier, displacing about 42% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the JY15 carries the more powerful rig (51.1 vs 35.1), favouring lighter-air performance.
- By the capsize screening formula the JY15 rates better for offshore work (3.59 vs 3.79).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
