Question 1797Navigation General70% to pass
You are navigating in pilotage waters using running fixes. The maximum time between fixes should be about _______________.
AI Explanation
The correct answer is B) 30 minutes.
In pilotage waters, the maximum time between running fixes should be about 30 minutes. This is because in pilotage waters, where the vessel is navigating close to shore or in restricted waters, the vessel's position needs to be fixed frequently to ensure safe navigation and avoid groundings or collisions. Taking fixes at intervals greater than 30 minutes may result in unacceptable position errors that could jeopardize the vessel's safety.
The other options are incorrect because 4 hours (A) is too long, 5 minutes (C) is too short, and 1 hour (D) is also too long for the required frequency of position fixing in pilotage waters.
