Precision 15 vs Precision 23: the short version
- The Precision 23 is the larger boat at 23.4 ft7.14 m LOA versus 15.0 ft4.57 m for the Precision 15.
- The Precision 23 is heavier, displacing about 528% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Precision 15 carries the more powerful rig (35.1 vs 21.7), favouring lighter-air performance.
- The Precision 23 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Precision 23 rates better for offshore work (2.52 vs 3.79).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
