A vessel sounds one short blast. This signal indicates the vessel __________.

When a vessel sounds one short blast, it is signaling its intention to alter course to starboard. This is an important maneuvering signal used by vessels to communicate their actions to nearby vessels to prevent collisions and ensure safe navigation. According to the International Regulations for Preventing Collisions at Sea (COLREGs), specific sound signals are established to convey clear messages about a vessel’s intentions.

The one short blast specifically indicates that the vessel will turn to its right (starboard), allowing other vessels in the vicinity to anticipate and respond appropriately to the change in course. Understanding this signal is crucial for maintaining safety on the water, as it helps to maintain situational awareness among mariners.

The other options represent different sound signals or actions. For instance, altering course to port would be indicated by two short blasts, while stopping the vessel would typically be communicated through a series of short and long blasts. A signal indicating distress usually involves a different kind of communication, such as using specific distress signals or flags, not just a single blast.
