What is the duration of a prolonged blast of the whistle?

The correct duration for a prolonged blast of the whistle is 4 to 6 seconds. This duration is standardized and is important for communication on the water, especially for signaling between vessels. A prolonged blast serves to alert others of your presence or intentions and can be a critical safety measure in preventing collisions or misunderstandings amongst boaters.

Longer blasts, whether accidentally prolonged or intentionally extended, could lead to confusion regarding navigational signals. Understanding the correct duration ensures that operators communicate effectively and adhere to the established boating regulations, fostering a safer environment on the water. This knowledge is particularly vital for party boat operators, who may share crowded waterways with various vessels.
