How Pricing Works
The total is made up of two parts:
- Yacht charter: from €150 per hour, with a two-hour minimum booking.
- Event extras: DJ, sound system, decoration, catering and photography are not included in that rate and are quoted separately based on what you choose.
The final figure depends on duration, group size, date and the extras you pick. Tell us your date and what you have in mind and we will put together a quote.

On board — Aziz, yacht parties
Birthdays go wrong in one specific way: the cake. It arrives in a box on a hot afternoon and by the time we cut it, it has travelled badly. Tell me when you book and we will keep it cold and bring it out on the dark stretch after Ortaköy, with the bridge lit behind you — that is the photograph you actually want. The music is yours too: send the playlist ahead and it will already be playing when you step on board.
Booking direct — no agency in the middle. Booking sites do not sell what is on this page: they sell seats, we charter you the whole yacht. Write to us and no reseller takes a commission out of your budget, and your request does not pass through a middleman who flattens it into a standard package. Constantine Yachts is run by AST Turizm — TÜRSAB licence no. A-805, on the Bosphorus since 1967. Your date, your boarding time, your route and your extras are agreed with the same people who prepare the yacht.
Booking and cancellation. Free cancellation up to 24 hours before departure — any prepayment is refunded in full. Inside 24 hours, contact us and we will try to move you to another slot. If the captain cancels a departure for safety, you choose: another day or a full refund. Full terms in our FAQ.

Frequently Asked Questions About Birthday Yacht Charter
How much does a birthday yacht charter cost in Istanbul?
From €150 per hour for the whole yacht, with a two-hour minimum — so a two-hour birthday cruise is €300 in total regardless of how many of you there are. Catering, cake and decorations are quoted separately and itemised in writing before you pay.
Can we bring a birthday cake?
Yes, you are welcome to bring your own, or we can arrange one. Tell us at the quote stage which you prefer and whether there are any dietary requirements.
Can the yacht be decorated before we arrive?
Yes. Anything we arrange is set up before boarding, so the deck is ready when you step on. If the birthday is a surprise, say so when you book and the crew will plan around it.
Is a yacht birthday suitable for children?
Yes. Life jackets are on board in children’s sizes, there is a toilet on every yacht, and the enclosed saloon means a cool or wet evening is not a problem. Tell us the ages when you book so the crew can prepare.
How many people can come?
Groups of 12 to 200 guests across our own and partner yachts, with the largest vessels from the partner fleet. A small birthday for a handful of people and a party for eighty want different yachts, so tell us both the number and the format.
Where does the yacht board?
From a pier at Karaköy, by gangway. The exact meeting point with photographs is sent with your booking confirmation.
What if the weather is bad on the day?
Charters run in rain — every yacht has an enclosed saloon as well as an open deck. If the captain cancels a departure for safety, you choose between rescheduling and a full refund. Free cancellation also applies up to 24 hours before departure.
Are there any hidden fees, port taxes or fuel surcharges?
No. The hourly price covers the yacht, its crew and the fuel for your route. Extras such as catering, decoration or a photographer are priced separately and agreed before you confirm, never added afterwards.
Who operates the yacht, and are you licensed?
Constantine Yachts is the boutique yacht brand of AST Tourism, an Istanbul operator licensed by TÜRSAB (licence A-805) that has worked the Bosphorus since 1967. Every departure sails with a professional crew.
How will we find the boarding point on the day?
Boarding is at Karaköy on the European side, a few minutes from the Galata Bridge and the Karaköy tram stop. Once your date is set we send the exact map pin and photographs of the pier, so nobody is searching on the day. Other piers such as Kuruçeşme or Bebek can be arranged on request.
From how many guests is a private yacht cheaper than per-person tickets?
A two-hour private charter starts at €300 for the whole yacht. A seat on a shared sunset cruise costs around €34. From roughly nine guests upward the private yacht works out cheaper per person, and the yacht is yours alone.
Is booking directly with you cheaper than booking through a platform?
Yes. Platforms add their commission to the same departure; the last time we compared our own listing, the direct price was about 4% lower. You also speak to the operator rather than a call centre.
Can we check your reviews before booking?
Please do. We are rated 5.0 on Google from 259 reviews, with more than 700 guest reviews in total across Google, Viator and GetYourGuide.
How much deposit do you take, and how do we pay?
A 30% deposit holds your date; the balance is due before departure. Payments run through Stripe over a secure SSL connection, so your card details are handled by the payment provider and never stored by us.
Can a guest who uses a wheelchair come on board?
Unfortunately not. Boarding is from the pier over a gangway with a step, and we would rather tell you now than have someone turned away on the day. If a guest has limited mobility but can manage a step with help, write to us and we will talk it through honestly.
Can we bring our dog?
Yes, pets are welcome on board. Let us know in advance so the crew can prepare for them.
Do children pay the full price?
No. On the shared group tour children under 3 travel free and ages 3 to 7 pay a child fare of €15. On a private charter the price covers the whole yacht, so children add nothing to it. Tell us their ages when you book so the crew can prepare.
Is it safe to bring young children?
Yes. The Bosphorus is sheltered water rather than open sea, so the crossing is calm. Life jackets are on board including children’s sizes, and the crew is told in advance how many children are aboard. On a private charter you also control the pace and the route.
Will anyone get seasick?
Very unlikely. The Bosphorus is a strait, not open sea, and the water is calm for most of the year. In years of hosting, seasickness has almost never been an issue — and if someone in your group is worried, we can keep the route close to the shore.
Do you sail in winter, and is it worth it?
Yes, year-round. Every yacht has an enclosed saloon as well as an open deck, so a cold evening does not cancel anything. Winter has fewer boats on the water, sharper light and, on the shared sunset tour, a lower fare — €26 instead of €34 from 3 November to 18 March.
What happens if the weather cancels our departure?
If the captain calls off a departure for safety, you choose: another date or a full refund. Cancellation is also free up to 24 hours before departure, so a bad forecast never costs you anything.
What safety equipment is on board?
Life jackets for every guest, including children’s sizes, and a professional crew on every departure. We operate as AST Tourism under TÜRSAB licence A-805 and have worked the Bosphorus since 1967.
Can you arrange halal, vegetarian or vegan catering?
Yes. Catering is quoted separately and built around your table, so halal, vegetarian, vegan and allergy requirements are straightforward — tell us when you enquire rather than on the day.
Can we bring our own music or a DJ?
Yes. On a private charter the sound system is yours: bring a playlist or bring a DJ. Tell us in advance if you are bringing equipment so the crew can plan the power and the setup.
How do we get to Karaköy for boarding?
Karaköy is one of the easiest points in Istanbul to reach. The T1 tram stops at Karaköy, city ferries call at the Karaköy pier, and the M2 metro at Şişhane is a short walk up the hill — as is the Tünel funicular from Beyoğlu. From Sultanahmet it is two tram stops. Once your booking is confirmed we send the exact map pin and photographs of the pier.
Is an overnight stay on the yacht possible?
Yes — that is a separate product. On an Istanbul yacht stay you sleep on board for two to four nights and the yacht becomes your hotel as well as your transport, from €1,400 per night for the whole yacht.
What does a family of four actually pay?
On the shared sunset tour: two adults at €34 and two children aged 3 to 7 at €15 comes to €98, and under-3s are free. A two-hour private charter is €300 for the whole yacht regardless of how many of you there are — which is why larger families usually end up chartering.
Is the yacht ours alone, or do we share it with other guests?
It is yours alone. A birthday charter is a private booking – the deck, the saloon and the crew are for your group only, and nobody else boards.
Can we bring our own food and drinks?
Yes, you are welcome to bring the cake, the snacks and the drinks yourselves. If you would rather not carry anything, catering from a light table to a seated dinner is arranged and priced separately before you confirm.
Which time slot works best for a birthday – afternoon or sunset?
The sunset slot is the one people book first, and we set it against the real sunset for your date. Afternoons suit birthdays with children or a swim stop; late evening suits a party, with the bridges and palaces lit.
Can we keep it a surprise from the person whose birthday it is?
Often the whole point. Tell us when you book and the crew works to it: guests board first, the yacht is decorated before anyone arrives, and the cake comes out at the moment you choose rather than whenever it is ready.
Can we add a swim stop to a birthday cruise?
Between roughly June and September, yes – we anchor in a quiet bay and put the swim ladder down. Tell us when you book so the route allows the time, because a swim stop is easier to plan in than to add on the day.
Does the price change if a few guests drop out?
No. A private charter is priced for the whole yacht, not per head, so late changes to the guest list do not change what you pay. Free cancellation applies up to 24 hours before departure.
