1 NAVIGATION RULES -INLAND- LIGHTS & SHAPES Lights on your boat are for the benefit of other boaters. If properly displayed, your lights indicate the type of vessel, size of vessel, direction of travel, mode of operation (underway vs. anchored), etc.With that information, the operators of vessels can apply the Nav Rules at night.Without properly displayed lights, the risk of night boating is greatly increased.Inland Navigation Rules Act of Rules 20 through 31Developed and provided courtesy of Ohio Dept.

18 More Lights 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
19 More Lights More Lights Fishing vessels (Rule 26) When making way through the water these vessels also display masthead, side and stern lightsVessel engaged in diving (Rule 27)
20 Day ShapesDay ShapesIn addition to lights, some vessels are required to display shapes to indicate a special circumstanceExample:A vessel towing with severely restricted maneuverability displays 2 balls and 1 diamond in a vertical line (Rule 27)Ball Diamond BallWhile recreational vessels typically do not carry dayshapes, the following rules still apply.Towing with severely restricted maneuverability
21 Day Shapes Day Shapes Cone shape, apex down Sailing vessels under sail and power must display a cone shape, apex facing downexcept a vessel less than 12 meters (39.4 feet) is not obliged(Rule 25)Under sail and power
22 Under 23 feet not required Day ShapesDay ShapesA 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 anchoragea vessel less than 7 meters (23.0 feet) at anchor and not in a narrow channel, fairway or where other vessels normally navigateBall(Rule 30)Under 23 feet not required
23 Day ShapesDay ShapesA 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 ShapesDay ShapesIf 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 visibilityUse of this dayshape does not affect use of the “diver down” flag. The red flag with a white diagonal stripe is used in addition to mark the location of the divers.Does not affect use of “diver down” flagSmall vessel engaged in diving
