Un buque de propulsión mecánica en navegación pero parado y sin arrancada en visibilidad reducida emitirá:In restricted visibility, a power-driven vessel under way but stopped and making no way through the water will sound:
Show the answer
Correct answer: c) At intervals of not more than two minutes, two prolonged blasts in succession with an interval of about two seconds between them.
Why it is correct
A power-driven vessel making way sounds one prolonged blast at most every two minutes. If stopped and making no way, it sounds two prolonged blasts about two seconds apart.
Why the others are not
- a) Three prolonged blasts is not a Rule 35 signal.
- b) This matches no signal. The long-and-two-shorts signal belongs to other vessels.
- d) Two minutes is the maximum interval between signals, not the length of a blast.
How to work it out in the exam
- One prolonged: I am moving. Two prolonged: I have stopped.
