Explanation:
In Texas, a vessel that is more than 39.4 feet in length is required to have certain sound signaling devices on board. The required devices are a whistle or horn, which are used to alert other vessels of your presence and intention, especially in conditions of reduced visibility.
Vessels of this size may also need to carry a bell, which is used in conjunction with the whistle or horn for sound signaling purposes according to navigational rules.
Sound signals are critical for the prevention of collisions on the water. The specific sounds made by these devices, such as a steady whistle or a series of short blasts, convey different messages to nearby boats regarding navigation and maneuvering.
