The Draft was estimated based on the present and projected levels of Gatun Lake for the following weeks, the Authority said.

However, vessels arriving after 10 April 2019, with drafts over 13.72 meters (45.0 feet) TFW may be allowed to transit, depending on the actual level of Gatun Lake at the time of transit, the Authority further noted.

Otherwise, they will be required to trim or off-load cargo in order to be allowed to transit.

Draft adjustments will be announced in 12-inch (30.5 cm) decrements, generally with at least four weeks advanced notice.

From 27 February, the maximum authorized draft for vessels transiting the neo-panamax locks has been 14.63 metres (48.0 feet) TFW.
