The green buoy should be on the left (port) side of the boat as you are entering port.
When returning from sea, the red navigational buoy should be passed on the port side (left side) of the vessel. This is consistent with the IALA buoyage system, where red buoys indicate the right side of the channel when heading upstream or returning to port. Following this guideline helps ensure safe navigation and avoids potential hazards.
