Abstract:

An apparent wave is a part of the sea record observed between two successive
upcrossings of the still water level. Integral formulas are given for intensities
of encountered waves that overtake a ship sailing in directional sea with
constant velocity. The formulas can be evaluated exactly in the case when
the directional spectrum is known and the sea is assumed to be Gaussian,
i.e. is a sum of noninteracting sinusoidal waves.
