2006 New York Code - Clearance And Ownership.

 
    §  75.  Clearance  and  ownership. Every commercial float shall have a
  clearance. Clearances may be obtained at such  places  along  the  canal
  system  and  at  such  other  points  as  the corporation may direct. No
  clearance shall be granted to any commercial  float  unless  the  person
  authorized  to issue such clearance has evidence that such float is duly
  registered in the office of the corporation. Each  float  shall  have  a
  separate  clearance and no part of the cargo shall be cleared to a place
  beyond  which  the  float  is  cleared.  The  corporation  may,  in  its
  discretion,  refuse  to  issue  a  clearance  for a vessel against whose
  registered owner there is an unpaid penalty involving  such  vessel  for
  the violation of rules and regulations adopted pursuant to this chapter.
