Dehler 25 vs O'Day 25: the short version
- The Dehler 25 and O'Day 25 are close in length (24.8 ft7.55 m vs 24.8 ft7.57 m ).
- The O'Day 25 is heavier, displacing about 23% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Dehler 25 carries the more powerful rig (20.3 vs 17.1), favouring lighter-air performance.
- The O'Day 25 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the O'Day 25 rates better for offshore work (2.01 vs 2.23).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
