Question

Under the IALA-A Buoyage system, a buoy marking the port hand of the channel when approaching from seaward may NOT have a? A) Yellow light. B) Black topmark. C) Red light. D) Green topmark.

Answer 1

Under the IALA-A Buoyage system, a port side buoy when approaching from seaward would be colored red and could have a red light. It wouldn't typically have a yellow light or a green topmark.

Step-by-step explanation:

The IALA-A Buoyage system refers to an international maritime buoyage system developed by the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA). Under this system, buoys are used to mark the safe water edges of channels and routes, primarily for navigational purposes. Specifically for the port side, or left side of the channel when approaching from seaward, the buoys would normally be colored red and could have a red light. They may or may not have a cylindrical topmark. Yellow lights or green topmarks are not typical for port hand buoys in the IALA-A system. Therefore, the correct answer is A) Yellow light and D) Green topmark.
