Hunter 170 vs Siren 17: the short version
- The Hunter 170 and Siren 17 are close in length (17.1 ft5.21 m vs 17.2 ft5.23 m ).
- The Siren 17 is heavier, displacing about 57% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Hunter 170 carries the more powerful rig (35.1 vs 26.9), favouring lighter-air performance.
- The Siren 17 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Siren 17 rates better for offshore work (2.94 vs 3.58).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
