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) • Vessel engaged in diving(Rule 27) • When making way through the water these vessels also display masthead, side and stern lights
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 DiamondBall 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 lessthan 12 meters (39.4 feet) is not obliged (Rule 25) Under sail and power
Day Shapes Ball • 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 (Rule 30) Under 23 feet not required
Day Shapes • A vessel restricted in its abilityto 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
Day Shapes • A vessel engaged in fishing shall display 2 cones in a vertical line with apexes together 2 cones with apexes together (Rule 26) Vessel engaged in fishing
Day Shapes • A vessel agroundshall display 3 ballsin a vertical line, if practicable 3 balls in avertical line (Rule 30)
