Patent ID: 7082355

Claim:
A method for monitoring wake wash associated with navigation through shallow waters, said method comprising selecting a Froude depth number acceptability limit, said Froude depth number acceptability limit representing the Froude depth number above which the wake wash associated with the navigation of a vessel is considered to represent a significant risk, said method further comprising, during the navigation of a vessel: measuring the speed of the vessel; measuring the depth of the water below the vessel; determining when the Froude depth number relating to the navigation of the vessel exceeds said Froude depth number acceptability limit, said determining including calculating the Froude depth number relating to the navigation of the vessel, said calculating including considering a relationship among the Froude depth number being calculated, the measured speed of the vessel, and the measured depth of the water below the vessel; and communicating when the Froude depth number relating to the navigation of the vessel is determined to exceed said Froude depth number acceptability limit.
