No, but boat
length does determine if a wave is both breaking and dangerous.
breaking wave height > boat length * ratio > (1/7) * wave length
ratio >= 30%
boat length * ratio > (1/7) * wave length
boat length > (1/7) * wave length / ratio
If wave height is 30% of your boat length and your boat length is greater than 47.6% of wave length then you will have both breaking and dangerous waves.
