Atoll vs CPT SST: the short version
- The Atoll and CPT SST are close in length (12.3 ft3.75 m vs 12.2 ft3.72 m ).
- The Atoll is heavier, displacing about 21% 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 2.87).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
