CS 36 Merlin vs Portman 36: the short version
- The CS 36 Merlin and Portman 36 are close in length (36.0 ft10.97 m vs 36.0 ft10.97 m ).
- The Portman 36 is heavier, displacing about 23% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the CS 36 Merlin carries the more powerful rig (17.6 vs 13.7), favouring lighter-air performance.
- The Portman 36 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Portman 36 rates better for offshore work (1.67 vs 1.96).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
