The Panama Canal Authority (ACP) has issued a ‘circular to shipping’ establishing certain temporary restrictions on vessel draught. This temporary and preventive action is taken due to the effects of El Nino, which results in the periodic warming of ocean waters in the tropical Pacific. The circular states that the maximum allowed draught of 11.89 metres (39 feet) in tropical freshwater will be effective from 18 April 2016. Vessels with a greater draught to 11.89 metres before or on 21 March will not have to follow the draught restriction, subject to security considerations. Vessels loaded after 21 March must comply with the measure.
