  1. NAVIGATION RULES-INLAND-LIGHTS & SHAPES Inland Navigation Rules Act of 1980 Rules 20 through 31 Developed and provided courtesy of Ohio Dept. Natural Resources

  2. Disclaimer • The Rules presented in this program are an overview of summarized versions of the Inland Navigation Rules. • This program should not be considered a substitute for a complete version of the entire Inland Navigation Rules. • The summarized rules in this program could be interpreted differently than the complete rules of the Inland Navigation Rules.

  3. Application of Lighting Rules(Rule 20) • Lighting rules shall be complied with: • in all weather • from sunset to sunrise local time • sunrise to sunset in restricted visibility • all other times it is deemed necessary

  4. Application of Lighting Rules (Rule 20) • No other lights shall be displayed except lights that: • cannot be mistaken for required lights • do not impair visibility of required lights • do not interfere with keeping a proper look-out

  5. Definitions for Lighting (Rule 21) Masthead light- 225º white light showing ahead to 22.5º abaft the beam on both sides Sidelights- 112.5º green light (starboard) and red light (port) showing ahead to 22.5º abaft the beam May be one combined light on vessels less than 20 meters Sternlight - 135º white light showing 67.5º from right aft on each side All-round light- 360º white light showing all around the horizon

  6. Visibility of Lights (Rule 22) Type of light < 12 meters 12 meters or >Masthead light 2 miles 3-5 miles Sidelights 1 mile 2 miles Stern light 2 miles 2 miles All-round light 2 miles 2 miles

  7. Zones Crossing Overtaking Overtaking Head-On Overtaking Crossing

  8. Power-Driven Vessel Underway (Rule 23) • Vessels less than 20 meters (65.6 feet) Sidelights may be combined in one light. Under Power

  9. Power-Driven Vessel Underway (Rule 23) • Vessels less than 12 meters (39.4 feet) May exhibit an all-around light instead of masthead and stern lights.

  10. Sailing Vessel Underway (Rule 25) • Vessels less than 20 meters (65.6 feet)

  11. Sailing Vessel Underway (Rule 25) • Vessel less than 7 meters (23 feet) • Exhibit same lights as largersailing vessels if practical. • If not practical, exhibit an electric torch or lantern showing a white light in time to prevent collision.

  12. Vessel Under Oars (Rule 25) • May exhibit lights for sailing vessels or have ready at hand an electric torch or lighted lantern showing a white light in time to prevent collision.

  13. Vessel at Anchor (Rule 30) • Vessel at anchor (less than 50 meters)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

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

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

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

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

  18. 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 • 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

  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) Ball DiamondBall Towing with severely restricted maneuverability

  21. 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

  22. 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

  23. 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)

  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”. (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

  25. 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

  26. Day Shapes • A vessel agroundshall display 3 ballsin a vertical line, if practicable 3 balls in avertical line (Rule 30)

  27. Day Shapes Vessel Shape Exemptions Vessel Under Sail & Power Cone > 12m Anchored Ball > 7m (not in channel) > 20m (in anchorage) Aground 3 Balls (vert. line) > 12m Not Under Command 2 Balls (vert. line) > 12m Restricted in Ability 1 Ball + 1 Diamond > 12m (except dive boats) to Maneuver + 1 Ball (vert. line) Diving (restricted in Same as above Shapes not practical ability to maneuver)(must display “A” flag) Fishing (commercial) 2 Cones (vert. line) > 20m (but must display (nets or trawling) basket shape) Vessel Towing Diamond Tow > 200m Vessel Being Towed Diamond Tow > 200m
