Pilotage is not compulsory for transit basis vessels for Dardanelles & Bosphorus straits but we are strongly recommended that pilots be used during navigation through the Straits so as to minimize the risk of accidents as much as possible to use specialy during Bosphorus passage due to strong current and heavy traffic.
If vessel going to any Marmara Sea Ports or coming from any Marmara Sea Ports, Pilotage is compulsory for Bosphorus and Dardanelles straits.
