Interlake vs Windrose 5.5: the short version
- The Interlake and Windrose 5.5 are close in length (18.0 ft5.49 m vs 18.0 ft5.49 m ).
- The Windrose 5.5 is heavier, displacing about 131% 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 18.4), favouring lighter-air performance.
- By the capsize screening formula the Windrose 5.5 rates better for offshore work (2.80 vs 2.89).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
