Crown 23 vs Sonar: the short version
- The Crown 23 and Sonar are close in length (23.0 ft7.01 m vs 23.0 ft7.00 m ).
- The Crown 23 is heavier, displacing about 81% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Sonar carries the more powerful rig (25.9 vs 17.7), favouring lighter-air performance.
- The Crown 23 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Crown 23 rates better for offshore work (1.97 vs 2.46).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
