Prindle 18 vs Prindle 18-2: the short version
- The Prindle 18 and Prindle 18-2 are close in length (18.0 ft5.49 m vs 18.0 ft5.49 m ).
- The Prindle 18-2 is heavier, displacing about 12% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Prindle 18 carries the more powerful rig (72.3 vs 71.7), favouring lighter-air performance.
- The Prindle 18-2 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Prindle 18 rates better for offshore work (4.56 vs 4.71).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
