“Inner Harbor Navigation Canal (IHNC) Lock mariners are advised that the mooring bits located in the long guidewall on the canal end of the Inner Harbor Navigation Canal (IHNC) Lock are very unstable; you may use the wall to line up on when locking but DO NOT tie off on the mooring bits.

• All tows with more than one barge are required to use an assist vessel with a line attached at the head of the tow.
• Single barge tows will be permitted to lock westbound without an assist vessel.
• Do not attempt to “pivot” on the guidewall, therefore, vessels must flatten-out before making contact with the guidewall.”
