The seven daily booking slots for neopanamax vessels are offered in addition to the 23 slots available each day for transit through the panamax locks, it said.
"This increase is the direct result of our efficient, streamlined use of resources and effective collaboration as we meet the growing demand for transits through the expanded canal," said Panama Canal Administrator Jorge Quijano.
The additional slot is now available for ships transiting from the Pacific to the Atlantic, and was first offered in September through a special competition.
Containership will have preference. If none are interested, the slot will be awarded to any vessel that participated in the special competition.
