Interlake vs Prindle 18: the short version
- The Interlake and Prindle 18 are close in length (18.0 ft5.49 m vs 18.0 ft5.49 m ).
- The Interlake is heavier, displacing about 94% 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 37.3), favouring lighter-air performance.
- By the capsize screening formula the Interlake rates better for offshore work (2.89 vs 4.56).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
