If your vessel is 26 feet or more in length and operating on Louisiana state waters what sound-producing device(s) must be carried?

In Louisiana state waters, if your vessel is 26 feet or more in length, you are required to carry a sound-producing device such as a whistle, horn, or bell. This device must be capable of producing a sound that can be heard for at least one-half mile. Additionally, vessels must comply with the U.S. Coast Guard's requirements for sound signals, particularly when operating in reduced visibility or during specific maneuvers.
