Bow Slamming - Probability Estimate
Probability of bow slamming per wave encounter (Ochi 1964) based on bow forefoot emergence and relative vertical velocity.
Slam probability per encounter
0.0096 -
Formula, assumptions, and limits
Ochi 1964 model. Critical velocity = 0.093·√(g·L) per Ochi-Motter. σ values from strip-theory seakeeping analysis at design sea state.
