How many short blasts indicate an alteration of course to starboard?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (A)

One short blast is the designated sound signal that indicates an alteration of course to starboard for vessels operating in restricted visibility or when communicating with other vessels. This standard is part of the International Regulations for Preventing Collisions at Sea (COLREGs) which ensures that all mariners follow the same sound signaling conventions. The use of one short blast is universally understood by boat operators to mean that the vessel making the signal is intending to turn to starboard (the right side of the vessel when facing forward). This is crucial for avoiding collisions and improving communication between vessels, especially in busy or narrow waterways. Understanding this signaling helps maintain safety on the water and ensures that all mariners are aware of each other's intentions.
