Suezmax tankers (\u0026lt;300 m LOA) can safely navigate the Turkish Straits while maintaining acceptable margins of safety. Tankers \u0026gt;300 m LOA can transit the Turkish Straits, but will be subject to additional restrictions.\u003c\/p\u003e\n\u003cp\u003eManaging traffic in the Turkish Straits is a challenge, with one-way traffic measures leading to a transit time of broadly 12 hours Northbound and 12 hours Southbound (typically led by a tanker). This all results in the average waiting time for a ship to enter the Bosphorus Southbound being 14.5 hrs for large ships waiting in 'hold'. Such waiting times can increase to 3-4 days, or even a week on occasions, due to heavy traffic or other circumstances such as poor weather or as a result of a major incident in the Turkish Straits. The Guide clearly sets out all of this information to provide scheduling advice for the Master.\u003c\/p\u003e\n\u003cp\u003eIn the Turkish Straits, vessels may encounter strong currents, with rates in excess of 7 knots, while navigating in confined waterways that narrow to only 698 m at points, as well as having to safely make large alterations of course of up to 80?. In addition to these challenges, concentrations of traffic are often heavy in the Bosphorus, as ferries and local traffic make over 2,500 crossings of the waterway per day.\u003c\/p\u003e\n\u003cp\u003eThis 2026-27 Guide provides clear and comprehensive guidance for the Master and navigating officer, accompanied by annotated chartlets for each stage of the transit, all presented in an easy-to-use format and layout.\u003c\/p\u003e\n\u003ch4\u003eContents Listing\u003c\/h4\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in;
