Baymaster 18 vs Interlake: the short version
- The Baymaster 18 and Interlake are close in length (17.9 ft5.46 m vs 18.0 ft5.49 m ).
- The Baymaster 18 is heavier, displacing about 31% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Interlake carries the more powerful rig (37.3 vs 26.0), favouring lighter-air performance.
- By the capsize screening formula the Interlake rates better for offshore work (2.89 vs 2.92).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
