Connecticut Safe Boating Practice Test

If you wish to pass a vessel on your starboard (right) side, what sound signal should you use?

1. One short blast

2. Two short blasts

3. Three short blasts

4. Five short blasts

The correct answer is: Two short blasts

Using two short blasts is the correct sound signal to indicate your intention to pass another vessel on your starboard side. In maritime signaling, these sound signals are standardized to promote safety and understanding between vessels. When you use two short blasts, you are communicating to the other vessel that you plan to pass on their starboard side. This convention helps prevent confusion and ensures that both vessels are aware of each other's maneuvers. Sound signals are particularly important in situations where visibility is limited, such as in fog or at night, allowing vessels to navigate safely. The other options represent different maneuvers or intentions. For example, one short blast indicates turning to starboard, three short blasts signify that you are operating astern propulsion, and five short blasts typically signal danger or that the other vessel does not understand your intentions. Understanding and using these signals appropriately is crucial for safe navigation on the water.
