A powerboat underway in fog should sound a prolonged blast on its horn at intervals of not more than two minutes. This signal alerts other vessels to its presence in low visibility conditions. Additionally, if the vessel is maneuvering or making way, it may also sound short blasts as required for specific maneuvers. Always be prepared to adjust your signals based on the surrounding conditions and the presence of other vessels.
One prolonged blast plus two short blasts every two minutes
None. A vessel underway under normal conditions does not need to make any sound signal.If the vessel ceases to make way it still does not make a sound signal unless special circumstances apply.
One prolonged blast every two minutes
In reduced visibility, the powerboat should maintain a safe speed and be prepared to take evasive action. According to navigation rules, the powerboat should give way to the sailboat, as sailboats under sail have the right of way. The powerboat should sound its horn to signal its presence and ensure the sailboat is aware of its approach. It may also consider using radar or other navigational aids to enhance visibility and ensure safe passage.

A powerboat at anchor during periods of restricted visibility is required to sound a specific signal: it must make one short blast every minute. This signal helps to alert other vessels in the vicinity of its presence. Additionally, the boat should display appropriate anchor lights to enhance visibility.

When a powerboat approaches a sailboat on its starboard side in darkness or reduced visibility, it must take care to maintain a safe distance and reduce speed to avoid collision. The powerboat should also ensure that its navigation lights are illuminated and clearly visible. Additionally, it is important to sound an appropriate signal to alert the sailboat of its presence and intentions. Finally, the powerboat operator should be prepared to take evasive action if necessary.
When being approached by another powerboat, the operator of powerboat A should assess the situation to determine the right of way. According to maritime rules, if powerboat B is on the operator's starboard side, powerboat A should maintain its course and speed, while if B is on the port side, A should yield by altering course or speed to avoid a collision. It’s crucial to communicate intentions clearly, using sound signals if necessary, and always prioritize safety by being vigilant and prepared to take evasive action if needed.
In restricted visibility, a power-driven vessel underway is required to sound one prolonged blast every 2 minutes. This signal is meant to indicate the vessel's presence to other nearby vessels in low visibility conditions. The prolonged blast lasts for about 4 to 6 seconds. This sound signal helps enhance safety by alerting others to the vessel's location, allowing for better navigation and collision avoidance.
When boating on Alabama waters in an 18-foot powerboat, a sound-producing device is required. This can be a whistle, horn, or any other device that can produce an efficient sound signal. It must be audible for at least half a mile. Additionally, if the vessel is 26 feet or longer, a bell or a similar device is also required.
