The Panama Canal has raised its daily transit capacity to 34 slots after enhancing water availability across its watershed. The latest update gives one more reserved slot for Super-category vessels using the Panamax locks, increasing their daily allotment from 18 to 19 slots, according to an Advisory to Shipping from the Panama Canal Authority (ACP).

In addition to the increase in transit capacity, the Authority has also increased the maximum authorized draught for vessels using the Neo-Panamax locks. The limit is now 50 feet (15.24 meters) and will stay in place until further notice.

The ACP says changes take effect immediately and are supported by improved lake levels and favorable hydrological forecasts. The conditions enable the waterway to optimize its use of water and ensure the long-term sustainability of canal operations.

“The canal now has a daily capacity of 24 slots for the Panamax locks and 10 for the Neo-Panamax locks with the added reservation slot. This capacity will be available subject to the relevant booking periods and reservation procedures established by the Authority.

Different booking procedures depending on the date of transit

The extra slot will be available through the canal’s current reservation system, and the reservation process will vary based on the requested transit date.

The additional capacity will be made available through Period 3 on an auction basis for bookings covering 12 to 17 November 2026. Period 2: the Special Competition Special Competition access to transit dates between 18 – 23 November 2026.

The additional capacity will be made available to the normal opening of the Second Competition Period from 24 November 2026.

The Panama Canal Authority has also highlighted the necessity of guaranteeing reservations are done in advance. The ACP states that the Transit Reservation System is the only method for securing a transit date. Vessels arriving without a firm reservation may therefore face long waiting times and operational delays.
