Hampton One-Design vs Mercury 18: the short version
- The Hampton One-Design and Mercury 18 are close in length (18.0 ft5.49 m vs 18.0 ft5.49 m ).
- The Mercury 18 is heavier, displacing about 46% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Hampton One-Design carries the more powerful rig (33.8 vs 25.1), favouring lighter-air performance.
- The Mercury 18 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Mercury 18 rates better for offshore work (2.07 vs 2.54).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
