Knarr vs Southern Cross 28: the short version
- The Knarr and Southern Cross 28 are close in length (30.4 ft9.28 m vs 30.4 ft9.27 m ).
- The Southern Cross 28 is heavier, displacing about 73% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Southern Cross 28 carries the more powerful rig (15.9 vs 14.1), favouring lighter-air performance.
- The Southern Cross 28 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 1.67).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
