BOTH INTERNATIONAL & INLAND Which statement is TRUE concerning wing in ground (WIG) craft when taking off, landing and in flight?

Correct Answer: Option C — A WIG shall keep well clear of all vessels and avoid impeding their navigation.

Rule 18(f) explicitly states that a Wing-in-Ground (WIG) craft, when taking off, landing, and in flight, shall keep well clear of all other vessels and avoid impeding their navigation. This requirement ensures that the high-speed nature of WIG craft does not interfere with the safety of conventional maritime traffic.
