Question 4129 is wrong (or I experienced a glitch in the system).
The question states:
"BOTH INTERNATIONAL & INLAND Which vessel MUST show two masthead lights in a vertical line?"
I answered: "A power-driven vessel less than 50 meters in length with a 20 meter tow"
What it said was the answer: "A vessel not under command"
This is clearly incorrect as Rule 24 Towing and Pushing (a)(i) states: "...two masthead lights in a vertical line."
Rule 27 (a) does not specify any masthead lights for vessels not under command. 27(a)(i) states: "two all-around red lights in a vertical line where they can best be seen," not masthead lights.
Other available are answers: "A sailing vessel towing a small vessel astern" or "A vessel engaged in dredging"
(I would have commented on the question but was not logged in and after I logged in I got a different question when I went back.)
