  1. TYPES OF SHIPS BY SCHEDULE (timetable): a) Liners (linijska plovba) – definedthehour at whichtheyhave to be at a port to take up cargo or passengers (ETA – estimated time ofarrival, ETD – estimated time ofdeparture, portofloading, portofdischarge, portsofcall) b) Tramps (prosta plovba) – these are not knownmuch in advance (they go wherethere is cargo)

  2. VESSELS USED FOR THE TRANSPORTATION OF CARGO AND/OR PASSENGERS
