Mirage 27 vs Sea Sprite 27: the short version
- The Mirage 27 and Sea Sprite 27 are close in length (27.9 ft8.51 m vs 27.9 ft8.51 m ).
- The Sea Sprite 27 is heavier, displacing about 46% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Mirage 27 carries the more powerful rig (16.7 vs 14.1), favouring lighter-air performance.
- The Sea Sprite 27 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Sea Sprite 27 rates better for offshore work (1.80 vs 2.14).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
