Knarr vs Nonsuch 30: the short version
- The Knarr and Nonsuch 30 are close in length (30.4 ft9.28 m vs 30.3 ft9.24 m ).
- The Nonsuch 30 is heavier, displacing about 114% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Nonsuch 30 carries the more powerful rig (18.0 vs 14.1), favouring lighter-air performance.
- The Knarr scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Knarr rates better for offshore work (1.64 vs 2.18).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
