Comet vs Isotope: the short version
- The Comet and Isotope are close in length (16.0 ft4.88 m vs 16.0 ft4.88 m ).
- On sail area/displacement the Isotope carries the more powerful rig (70.0 vs 53.0), favouring lighter-air performance.
- By the capsize screening formula the Comet rates better for offshore work (3.45 vs 4.61).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
