ABSTRACT:
A marine vessel (102) is operable to emit an audible signal based upon the velocity status of the marine vessel (102). The marine vessel (102) includes a first processor component (340) operable to determine the velocity of the vehicle based upon signal inputs (140, 142, 144). The marine vessel (102) further includes a database (310) containing a set of at least two audible signals. A second processor component (300) is operable to select an audible signal from the set of at least two audible signals based on the velocity of the marine vessel (102). A loudspeaker (110) emits the selected audible signal from the marine vessel (102).
