Laser 28 vs Laser 4.7: the short version
- The Laser 28 is the larger boat at 28.4 ft8.66 m LOA versus 13.8 ft4.20 m for the Laser 4.7.
- The Laser 28 is heavier, displacing about 2938% more, which usually means a steadier but slower-to-accelerate hull.
- The Laser 28 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Laser 28 rates better for offshore work (2.40 vs 3.60).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
