The inquiry that pushed me to build this service came from an Israeli family, and the first question was not about the yacht, the islands or the price. It was about the chef, and whether the food could be properly kosher. Not kosher-style. Kosher, with a standard behind it their rabbi would recognise.
I have since built that answer into a dedicated kosher charter service, and this is the long version: how a fully kosher week at sea actually works in Greek waters, what it costs, where its limits are, and why Greece is quietly the most kosher-capable charter destination just over two hours from Ben Gurion. Everything below rests on what the organisations running this infrastructure publish, not on assumptions. Where I do not know something, I say so.
Can a charter week in Greece actually be fully kosher?
Yes, and not in the loose sense the travel industry sometimes uses that word. Glatt kosher catering prepared under rabbinic supervision operates from Athens and delivers across Greece, including Mykonos and Santorini, with 3 to 5 days notice. Chabad of Greece maintains houses in Athens, Thessaloniki, Crete and Rhodes, and Chabad of Mykonos runs an active house with its own kosher catering and a kosher shop. That is the supply side, and it is real.
The demand side is where a broker earns his keep. A yacht is a small, privately run kitchen at sea. Making that kitchen kosher for a week is not a matter of goodwill, it is a matter of protocol: what comes aboard, what it travels in, what it is cooked on, who touches it, and what happens when the boat is two islands away from the nearest supervised kitchen. All of that is arrangeable. None of it arranges itself.
How does kosher food work on a boat that is not yours?
There are three proven formats, and the right one depends on your standard, not mine. I set them out in rising order of strictness.
The first is sealed glatt meal service. Every meal is prepared under rabbinic supervision in Athens, sealed, chilled and delivered to the yacht, where the crew reheats and plates without ever opening the kosher chain. This is the format that works everywhere, on any yacht, because the galley itself never needs to change. It needs 3 to 5 days of ordering lead, which is why the provisioning conversation happens weeks before you fly, not on the dock.
The second is the yacht's own chef cooking exclusively kosher ingredients on dedicated or disposable equipment. Fresh fish bought at the morning market, kosher-certified dry stores loaded in Athens, new pans and boards that belong to your week alone. Families who keep kosher at home but travel on ingredients rather than seals tend to choose this, because it keeps the theatre of a private chef, and Greek produce deserves that theatre.
The third is a galley koshered for the week under your rabbi's guidance, the full standard, arranged well in advance. It is the least common of the three and the most demanding of lead time, and I would rather tell you that plainly than promise it casually. The formats, with their trade-offs, are defined in our kosher charter glossary entry as well. Whichever you choose, it goes into the charter file in writing before you board. Your standards are not a conversation to have twice, and never on holiday.
What does Shabbat at anchor actually look like?
The yacht is moored or anchored before sunset on Friday and does not move until after havdalah. That single sentence reorganises the whole week, and it is the reason a kosher itinerary must be designed rather than adapted. The route runs its miles Sunday to Friday afternoon, then stops somewhere worth stopping.
Where it stops is your choice between two goods. Moor at Mykonos and you have walking access to the Chabad house for Friday night, with the town's noise a street away. Anchor in a sheltered bay and you have the other version: a still boat, prepared meals, the swimming platform down, and the kind of quiet the Aegean only gives to people who are not going anywhere. Candles lit at anchor as the light goes soft over the water: Shabbat at sea makes its own argument.
The crew works around your observance, not through it. Meals prepared ahead, no engine work, nothing asked of you and nothing done that should not be done, all of it in the written brief. If you want to see how a crewed day runs in general, I have described the hour-by-hour rhythm of a charter week elsewhere. The Shabbat version is that rhythm with the sails furled and the clock handed back to you.
Which yacht is right for a kosher week?
For most kosher families the answer is a crewed catamaran, and for reasons that have nothing to do with fashion. Two hulls give you a galley with genuine working space, which matters enormously when that galley is running sealed meal service or dedicated equipment. The beam gives a large, stable cockpit table where three generations actually eat together. And the stability itself matters for exactly the guests kosher weeks tend to include: grandparents and small children. I have made the full case for the catamaran separately; the kosher week is that case at its strongest.
To put real numbers where the adjectives usually go, three tiers from our own fleet. S/CAT World's End is a 19-metre crewed catamaran, five cabins sleeping ten, four crew including an award-winning chef, from €20,500 per week plus expenses. That chef is the point: a kitchen already run to competition standard adapts to a written kosher protocol better than any kitchen improvising one.
A step up in pace, M/Y ONE, a 27-metre motor yacht with four crew, runs €45,000 to €49,000 per week plus expenses, and buys the speed that turns long passages into short ones, which is precisely what a Friday-anchored week wants: more miles covered Sunday to Thursday, calmer margins before sunset. At the top of what I would call the family tier, M/Y ARIELA carries twelve guests in six cabins with eight crew at €105,000 to €120,000 per week plus expenses, the multi-generational format where the interior team is large enough to run a dedicated kosher service without the rest of the boat noticing the logistics.
If the group is five couples or a family that counts in double digits, the five-cabin catamaran class is its own subject, and I keep a current shortlist of the best five-cabin catamarans in Greece for exactly this conversation.
What does a kosher charter week honestly cost?
The base rate of the yacht does not change because your food is kosher. What changes is the provisioning, and provisioning lives in the APA, the advance fund, typically 25 to 35 percent of the base rate on sail and 30 to 40 percent on motor, that covers food, drink, fuel, berths and port dues, and is reconciled against receipts at the end of the week with any balance returned to you. Supervised catering and island delivery are APA line items like any other provisioning, only better organised.
On top of base and APA sits Greek charter VAT, and here precision matters because the internet rounds it wrong. The rate on a weekly crewed charter follows the yacht's certification and runs 5.2, 6.5, 7.8 or 12 percent. There is no single flat number, and any quote that gives you one deserves a follow-up question. A discretionary crew gratuity sits on top of everything. For the full market picture, rate bands and how the season prices, the Greek Charter Index is the reference I keep current.
How close is Greece from Israel, really?
Athens is about 2 hours 10 minutes nonstop from Tel Aviv, with roughly 50 direct flights a week in season across EL AL, Aegean, Arkia, Israir and others. A morning flight lands you aboard by mid-afternoon. Greece and Israel also share the same clock through the summer, both at UTC plus 3, so there is no jet lag on either end and no odd-hours coordination while we plan. Israeli passport holders enter visa-free for up to 90 days in any 180. I keep a dedicated page for Israeli clients with the practicalities in one place.
Measure the alternatives honestly and the map makes the decision. The French Riviera, the Balearics and the Caribbean are all fine charter waters, and all of them are far. Greece is the only destination of that rank where the flight is shorter than the first lunch.
What does the week itself look like?
The shape I recommend most often boards at Alimos on Sunday with the kosher provisioning already loaded and checked, and spends its first night at anchor under the Temple of Poseidon at Cape Sounion. Monday and Tuesday take the quiet western stepping stones, Kea and then Syros, where Ermoupoli's neoclassical harbour is the most underrated evening in the Cyclades. Wednesday is Mykonos, which matters here for a reason beyond the postcards: an active Chabad house, kosher catering and a kosher shop, which makes it the natural mid-week stock refresh. Thursday is Delos in the morning, one of the great archaeological sites of the Mediterranean, and Rhenia's turquoise bays in the afternoon.
Friday the yacht positions early and is settled before sunset, at the marina if you want Chabad on foot, in a sheltered bay if you want the sea to yourselves. Shabbat is a day at rest, at anchor, everything prepared. Saturday night, havdalah and a short sail under the stars back toward Athens, which I consider the finest single hour of the whole format. It is a route, not the route; the same logic bends around Santorini, the Saronic or a Rhodes start whenever the group prefers.
Where does the food come from once we are out among the islands?
From two directions, and the itinerary is drawn so they meet the boat rather than the boat chasing them. The first direction is Athens. The supervised kitchens there treat the islands as a delivery zone, not a frontier: sealed glatt orders are delivered to Mykonos, Santorini and beyond, with the 3 to 5 day lead I keep repeating because it is the one number that governs everything. On a properly planned week, the mid-week delivery is booked before you have boarded, and the crew signs for it while you are swimming.
The second direction is Mykonos itself. The island's Chabad house runs its own kosher catering, and there is a kosher shop in town, which makes Mykonos the one place in the Cyclades where you can walk ashore and restock rather than wait for a van from Athens. This is why my kosher routes treat Mykonos as the logistical hinge of the week even for families who have no interest in its nightlife: you arrive with half the provisions gone, you leave whole again. Santorini has glatt delivery from Athens on the same lead time, so a caldera finale does not break the chain, it just needs the order placed earlier.
And around the sealed kosher core sits everything Greece does without being asked. Fruit from the morning market, tomatoes that need no apology, honey, olives and olive oil chosen with the same seriousness other countries reserve for wine. Whatever format your kashrut takes, the produce of the Aegean fits inside it, and a good chef makes that the week's quiet luxury: simple things, perfectly fresh, eaten on deck with the water changing colour behind them.
What should we ask any broker before booking a kosher week?
Five questions, and the speed of the answers tells you more than the answers themselves. Ask who, by name, prepares the kosher food and under whose supervision; a broker who has actually arranged this before answers without checking. Ask for the galley protocol in writing before the contract, not after; if the protocol only exists once you have paid, it does not exist. Ask who owns the dedicated equipment for your week and what happens to it afterwards. Ask what the plan is if an island delivery misses the boat, because ferries have weather days and a real plan names the backup, not the hope. And ask how the Friday mooring is guaranteed in a month when marinas run full; the answer should involve a booked berth or a named bay, never the word usually.
These are the kosher-specific questions. The general ones, licensing, MYBA membership, how the money is held, apply exactly as they do to any charter, and I have written a separate guide on how to verify a charter broker before you wire a deposit to anyone, myself included. A family trusting a stranger with both its holiday and its standards is owed that much diligence, and the brokers worth using will welcome it.
I will also say what I do not offer, because the honest list is shorter and more useful than the glossy one. I do not certify kashrut; rabbis do, and where your standard needs supervision aboard, the arrangement is made with the supervising authority rather than improvised by a charter company. I do not promise what a caterer has not confirmed in writing for your specific dates. And I do not sell the third format, the fully koshered galley, on short notice, ever. Clients come back to this house year after year precisely because nothing was ever promised that could not be delivered.
When is a kosher charter not the right holiday?
I owe you the honest chapter. If your standard requires a fully koshered galley and your dates are three weeks away, I will probably decline rather than improvise, because that format needs real lead time to be done properly, and done properly is the only version worth paying for. If your group's picture of the week is heavy on late-night harbours and light on anchorages, the Friday-to-Saturday stop will feel like a brake rather than a gift, and you should hear that from me before you book, not after. And if you are set on peak August but cannot commit until summer, the yachts worth having will already be gone; September, incidentally, is the month I would steer a flexible kosher group toward anyway: warmer sea, quieter bays, easier caterer scheduling.
None of that is a reason not to charter. It is a reason to charter with the constraints on the table, which is the only way I work. The broader mechanics of a crewed charter in Greece, contracts, crew, what is included and what is not, are the same for a kosher week as for any other, and I have written them up plainly.
When should we book, and what happens next?
Earlier than a standard charter, because two calendars have to agree: the yacht's and the caterer's. The 2026 season is closing as I write this; the real question on the table is 2027. For July and August 2027, reserve by late winter. The 2027 season calendar is already open, and the families who book first take the best weeks and the best boats, every year, without exception. Once the yacht and format are set, everything else is detail work we do for you, down to what to pack.
If this is your family's kind of week, write to me with the month, the group and the standard you keep. I will come back with two yachts that fit, one alternative you probably have not considered, and a kosher plan in writing. The sea does not mind what your kitchen keeps. It only asks that you come.
