OK Dinghy vs Wave: the short version
- The OK Dinghy and Wave are close in length (13.1 ft4.00 m vs 13.0 ft3.96 m ).
- The Wave is heavier, displacing about 31% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the OK Dinghy rates better for offshore work (3.26 vs 4.47).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
