The term is sometimes used in lay discussions to describe the stream of spray that forms along the hull’s underside when a boat travels at speed or rides over waves. The character and intensity of keelsprays depend on hull shape, speed, trim, sea state, and the angle of attack.
In naval architecture, spray from the keel is analyzed as part of seakeeping and hydrodynamics. Designers seek
The term has no formal, standardized definition beyond describing a physical phenomenon associated with the hull–water
