539. BOTH INTERNATIONAL & INLAND The tow shown in illustration D024RR below is less than 200 meters in length and severely restricted in her ability to deviate from her course. Which shape (s) would be displayed by day from the vessel (s)?

The towing vessel must display ball-diamond-ball because the tow is less than 200 meters but the towing operation restricts its maneuverability; a diamond shape is not required on the last barge due to the tow's length, and only the restricted vessel displays the required shape.
