14 (Rule 23) Power-Driven Vessel Underway (Rule 23) ! !Typical of Great Lakes freighter

15 (Rule 24) Vessel Pushing (Rule 24) ! !Typical of Ohio River barges Barges Flashing

16 (Rule 24) Vessel Towing (Rule 24) ! !Object being towed !Vessel being towed DANGER: Unlighted cable spans between vessels

17 (Rule 30) Vessel Aground (Rule 30) ! !Vessel aground (less than 50 meters)

18 More Lights ! (Rule 27) !Vessel not under command (Rule 27) ! (Rule 27) !Vessel restricted in maneuverability (Rule 27) When making way through the water, these vessels also display masthead, side and stern lights. When at anchor these vessels also display anchor light

19 More Lights ! (Rule 27) !Vessel engaged in diving (Rule 27) When making way through the water these vessels also display masthead, side and stern lights (Rule 26) !Fishing vessels (Rule 26)

20 Day Shapes !In addition to lights, some vessels are required to display shapes to indicate a special circumstance !Example: #A vessel towing with severely restricted maneuverability displays 2 balls and 1 diamond in a vertical line (Rule 27) Towing with severely restricted maneuverability Ball Diamond Ball

21 Day Shapes !Sailing vessels under sail and power must display a cone shape, apex facing down #except a vessel less than 12 meters (39.4 feet) is not obliged Under sail and power Cone shape, apex down (Rule 25)

22 Day Shapes !A vessel at anchor must display a ball on the forward part of the vessel, except: #a vessel less than 20 meters (65.6 feet) at anchor in a special anchorage #a vessel less than 7 meters (23.0 feet) at anchor and not in a narrow channel, fairway or where other vessels normally navigate Under 23 feet not required Ball (Rule 30)

23 Day Shapes !A vessel restricted in its ability to maneuver shall display 2 balls and 1 diamond in a vertical line. !A vessel not under command shall display 2 balls in a vertical line. !Vessels less than 12 meters are not required, except when engaged in diving. (Rule 27)

24 Day Shapes !If the size of a vessel engaged in diving makes it impracticable to display shapes for restricted ability to maneuver, it shall display a rigid replica of the code flag “A”. Rigid replica of code flag “A” - One meter in height - All around visibility - One meter in height - All around visibility Small vessel engaged in diving Does not affect use of “diver down” flag (Rule 27)

25 Day Shapes !A vessel engaged in fishing shall display 2 cones in a vertical line with apexes together 2 cones with apexes together Vessel engaged in fishing (Rule 26)

26 Day Shapes !A vessel aground shall display 3 balls in a vertical line, if practicable 3 balls in a vertical line (Rule 30)
