Blazer 23 vs Sonic 23: the short version
- The Blazer 23 and Sonic 23 are close in length (23.0 ft7.01 m vs 23.0 ft7.01 m ).
- The Sonic 23 is heavier, displacing about 55% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Blazer 23 carries the more powerful rig (24.6 vs 17.1), favouring lighter-air performance.
- The Sonic 23 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Sonic 23 rates better for offshore work (2.02 vs 2.44).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
