Com-Pac 25 vs O'Day 28: the short version
- The Com-Pac 25 and O'Day 28 are close in length (28.2 ft8.59 m vs 28.3 ft8.61 m ).
- The O'Day 28 is heavier, displacing about 52% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the O'Day 28 carries the more powerful rig (15.7 vs 14.9), favouring lighter-air performance.
- The O'Day 28 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Com-Pac 25 rates better for offshore work (2.02 vs 2.11).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
