How long does a 'short blast' on the whistle last?

• A. 1 second
• B. 2 seconds
• C. 0.5 seconds
• D. 3 seconds

Answer: (A)

Short blasts are used for routine maneuvering signals and to convey an intention between vessels. The standard duration for a short blast is about one second, which makes it clearly distinguishable from a prolonged blast, which lasts several seconds (typically four to six). This timing distinction helps mariners communicate actions such as course changes or passing intentions clearly, even in rough conditions. So, when asked how long a short whistle blast lasts, the correct understanding is that it lasts roughly one second. Prolonged blasts, by contrast, are the longer signals used to indicate urgency or a change in actions.
