Question 174Navigation General70% to pass
Under the IALA-A Buoyage System, when entering from seaward a lateral system buoy to be left to starboard may display which topmark shown in illustration D046NG below?
AI Explanation
The correct answer is C.
Under the IALA-A Buoyage System, when entering from seaward, a lateral system buoy to be left to starboard may display a conical (can) topmark, which is shown in illustration D046NG option C. This is because the conical topmark indicates a port-hand mark, which should be kept to the vessel's port (left) side when entering from the sea.
The other options are incorrect because A and B show topmarks that do not correspond to the port-hand marking, and D shows a topmark that is not used in the IALA-A Buoyage System.
