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

More Lights ! Vessel not under command (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

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

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) Ball Diamond Ball Towing with severely restricted maneuverability

Day Shapes Cone shape, apex down ! 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 (Rule 25) Under sail and power

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 Ball (Rule 30) Under 23 feet not required

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)

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”. (Rule 27) Rigid replica of code flag “A” - One meter in height - All around visibility Does not affect use of “diver down” flag Small vessel engaged in diving
