Question 402Navigation General70% to pass
You are approaching an open drawbridge and sound the proper signal. You receive no acknowledgment from the bridge. Which action should you take?
AI Explanation
The correct answer is D) Approach with caution and proceed through the open draw.
The reasoning behind this is that when approaching an open drawbridge, if you have sounded the proper signal and received no acknowledgment from the bridge, you should proceed with caution through the open draw. This is in accordance with the U.S. Coast Guard regulations, which state that if no response is received, the vessel may proceed with caution through the open draw.
The other options are incorrect because: A) Holding in the channel is not necessary if the bridge is already open, B) Resounding the signal is unnecessary if the bridge is already open, and C) Waiting 400 yards from the bridge is overly cautious if the draw is already open.
