BOTH INTERNATIONAL & INLAND Which statement is TRUE concerning a towing vessel which, due to the nature of her work, is unable to keep out of the way of another vessel?

Correct Answer: Option D — By day, she would show the same shapes as a vessel restricted in her ability to maneuver.

Rule 27(b) states that a vessel restricted in her ability to maneuver shall exhibit three shapes in a vertical line (ball, diamond, ball). A towing vessel whose nature of work restricts her ability to deviate from her course must display these same shapes to indicate her limited maneuverability.
