What signal do you use when approaching a blind corner or dock?

When approaching a blind corner or dock, using a horn or whistle is the appropriate signal to notify other boaters of your presence. This practice is essential for maintaining safety on the water, as it serves as an auditory warning to alert others to your approach, especially in areas where visibility may be limited.

Sound signals are particularly effective in preventing collisions by providing a clear indication to nearby vessels that you are there and may be maneuvering in a way that could impact their course. In many boating regulations, using sound signals is mandated in specific situations to enhance safety.

Other options, like using a light beacon or flag, may not provide the same level of immediate and clear communication to oncoming traffic or other boaters in the vicinity. Hand signals can be effective but are primarily designed for close-range communication and may not be seen by others in larger or faster vessels. Therefore, using a horn or whistle ensures a broader reach and is a standard practice for alerting others when navigating potentially hazardous areas.
