Bosphorus Cruises & Boat Tours in Istanbul

What makes a boat trip safe and legal?

Any passenger boat operating on the Bosphorus must hold a valid seaworthiness certificate (technical inspection) proving the hull's soundness and compliance with safety standards, along with required life-saving equipment and a radio communication license, all under the supervision of the General Directorate of Maritime Affairs and the relevant Port Authority (Liman Başkanlığı). The Port Authority has the power to prevent any unseaworthy boat from putting out into the strait, and every boat is subject to a registered maximum passenger capacity that may not be exceeded.

In Istanbul specifically, operators of tourist boat trips are also required to obtain a maritime tourist operating permit from the Istanbul Metropolitan Municipality — a municipal requirement that supplements the seaworthiness certificate rather than replacing it.

Important points to know

Unlicensed boats, or those without a valid seaworthiness certificate — locally known as "kaçak tekne" — are not subject to periodic safety inspection, may exceed their permitted passenger capacity, and don't issue official receipts or invoices. If an accident or dispute occurs with such an operator, the passenger has no officially recognized insurance and no clear supervisory body to turn to afterward.

• A valid seaworthiness certificate is the first indicator that a boat is under official oversight
• The municipal maritime tourist transport permit is an additional requirement specifically in Istanbul
• The absence of a license means the absence of insurance and difficulty pursuing any legal follow-up after a problem occurs
