What is the fix interval in restricted waters?

The fix interval in restricted waters is set at 3 minutes to ensure that the vessel's position is accurately monitored and reported with sufficient frequency. In these navigational areas, where there are potential hazards such as shallow waters, traffic congestion, or other obstacles, more frequent position fixes are essential for safe navigation. The 3-minute interval allows the watch team to make timely decisions and adjustments to navigate safely, ensuring that they stay aware of the vessel's position relative to charted hazards or other vessels in the area. This frequency aligns with standards for maintaining situational awareness in more challenging navigational environments, helping to reduce the risk of grounding or collisions.
