About Constantine Yachts

Constantine Yachts is a family business on the Istanbul Bosphorus: we charter private yachts and run a daily shared sunset tour from Karaköy. The family business has been running since 1967, and our tours are operated by AST Turizm, a licensed travel agency registered with TÜRSAB (licence A-805).

What we do is simple. We give one yacht, for one evening, to one couple, one family or one company. It might be a sunset, a marriage proposal, a birthday or a business dinner. You plan the route, the time and the table with us, and the price is per yacht, never per person.

We have three yachts of our own. Tuana takes up to 12 guests, Crystall 32 and Constantine 44. For larger events we work with partner yachts such as White Istanbul, for up to 200 guests. We welcome our guests in Karaköy, at the pier in front of Balıkçı Kemal restaurant; other piers are possible on request.

If you would rather not charter a whole yacht, our shared sunset tour leaves every day, on our own yacht and with a live guide.
