Additional comments, suggestions, and recommendations: a. General port information (1) Barranquilla, Columbia. The ROCKAWAY arrived in Barranquilla on 27 July for a two day recreational visit. The Sailing Directions for the port were satisfactory except with regard to the information on pilotage. The Directions state that a pilot boat is on duty 3/4 miles west of the breakwater. Although advance arrangements were made through ALUSHA, the ROCKAWAY had to wait almost two hours for the compulsory pilot. When aboard, he stated that they attend the breakwater from 0500 to 1800 dur- ing the months of December through March. At other times they must be called on 2736 kcs. The pilots provided were competent and spoke English.
