Hydrodynamics & Physics Reference

Crest-to-Trough Heave Differential: In Sea State 4 to 5, the relative displacement between a floating dhow (displacement hull ~180 tons) and a Navy 11m RHIB creates vertical shearing velocity exceeding 2.8 m/s. Boarding operators climbing a flexible caving ladder face sudden load decoupling or crushing forces against the steel hull.

Man Overboard in Combat Gear: Tactical operators wearing ceramic plates, communications gear, weapons, and night vision carry 45–65 lbs of negative buoyancy before rapid manual or hydrostatic bladder inflation. Night ocean recovery during underway swell carries high peril.
