Atoll vs Open Fun 3,7: the short version
- The Atoll and Open Fun 3,7 are close in length (12.3 ft3.75 m vs 12.3 ft3.75 m ).
- The Open Fun 3,7 is heavier, displacing about 10% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the Atoll rates better for offshore work (2.46 vs 2.53).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
