§ 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.
