49er vs X boat: the short version
- The 49er and X boat are close in length (16.0 ft4.88 m vs 16.0 ft4.88 m ).
- The X boat is heavier, displacing about 127% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the X boat rates better for offshore work (3.13 vs 6.09).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
