420 vs Laser 4.7: the short version
- The 420 and Laser 4.7 are close in length (13.8 ft4.20 m vs 13.8 ft4.20 m ).
- The 420 is heavier, displacing about 35% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the Laser 4.7 rates better for offshore work (3.60 vs 3.82).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
