Isotope vs Nordica 16: the short version
- The Isotope and Nordica 16 are close in length (16.0 ft4.88 m vs 16.0 ft4.88 m ).
- The Nordica 16 is heavier, displacing about 236% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Isotope carries the more powerful rig (70.0 vs 19.9), favouring lighter-air performance.
- By the capsize screening formula the Nordica 16 rates better for offshore work (2.53 vs 4.61).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
