Can I go on a cruise that extends over Shabbat?

Can I go on a cruise that extends over Shabbat?


Being a passenger on a seafaring vessel on Shabbat per se does not present a problem, provided that the ship is owned1 and maintained by non-Jews, and the majority of the passengers are not Jewish.2

However, there are some issues of which you should be aware:

  • One may not embark on a sea journey on the three days preceding Shabbat. This means that you may not initially board a cruise after sunset on Tuesday evening.3
  • A little known rule is that it is forbidden to travel more than 2,000 cubits (approximately 0.6 miles) outside a populated area on Shabbat. This is called the prohibition of techumin. Now, this does not affect sea travel because techumin does not apply if the traveler is more than 10 handbreadths above the ground, and the boat is more than ten handbreadths above the seabed. But a traveler is affected by the laws of techumin if he disembarks on Shabbat. Consult a rabbi if your plans include a Shabbat disembarkation.
  • If you do disembark on Shabbat, ascertain that you are not carrying anything with you—including ID cards and boarding passes.
  • We may not operate electronic automated doors on Shabbat. So scout out the ship before Shabbat to see which doors you should avoid.
  • Another possible issue is keycards. Like many hotels, the passengers' doors on cruises are often operated by electronic cards—forbidden on Shabbat. You may, however, ask a non-Jew to open your door for you.
  • If you are having pre-packaged meals served to you by the galley staff, be aware that you may not eat any meals which were heated for you on Shabbat.4

While these are more-or-less the standard issues facing cruise goers, you would be well-advised to discuss the particulars of your trip with your rabbi, as there may be other issues unique to your situation.

Yours truly,

Rabbi Menachem Posner

P.S. May I suggest that you explore the option of taking a "Jewish cruise"? A simple Google search will find you several companies that offer such cruises on top-flight cruise ships. You can dine on delicious kosher cuisine instead of pre-packaged fare. You will also have access to prayer services and even Torah classes. A luxurious way to pamper the body while remaining mindful of the soul's needs too!


Practically speaking, this would preclude joining a cruise owned by an Israeli company if it will extend over Shabbat.


On Shabbat, it is forbidden for a Jew to benefit from "work" that is done for his benefit by a non-Jew. If the majority of the passengers are not Jewish, then the work that the non-Jewish crew is performing is primarily for the non-Jewish majority.

Hi Sara,
For your own peace of mind, maybe you want to run it by your Rav.
Take care and safe travels. Reply

Not sure if your comments were answered privately or not but I'd like answers to some of these comments specifically the one about sailing out of NY in Friday. And what about carrying on board the ship on shabbat. Reply

in response to Sara:

Hey Sara,

I can't speak for that cruise. I am sure that they spoke to a rav before making that schedule.

However, each person should speak to their own rav before undertaking such a trip.

About carrying on Shabbos on a ship. A ship would have the same rule as a hotel. Although a hotel is a building, and is a private domain, there are opinions (Dvar Avraham 3:30) who hold that one would need to make an eruv chatzeiros among all the passengers (and get the non Jews to nullify their rooms) in order to carry in the public areas like hallways and lobby.

Other opinions (Igros Moshe O.C. 1:141) say that an eruv chatzeiros is not necessary, and one may carry in the shared public spaces.

Speak to your own rav about which opinion you should follow. Reply

I took the exact same cruise, but at a different time. I did not have as many people, we did not even have close to a minyan. I did get to put on Tefilin and pray with the glaciers in the background.
If I ever went on a kosher cruise I would gain 50 lbs because I would just keep eating. With a Kosher cruise I just say to myself "I can't eat that it's not kosher". Reply

What about a cross-country US or Canada train trip that includes travel over Shabbat, if one boards prior to shabbat and doesn't disembark at station stops? It is similar to a cruise in many ways. Reply

food heated on shabbat If the food is pre-cooked, and heated by a non-Jew on Shabbat. What is the problem with that? Why can't I eat it? Reply

Chaim Wisconsin November 30, 2012

Cruising and departure dates Next January, 2013, Kosherica has a cruise sailing out of New York on a Friday, with several prominent guest speakers and singers on board, all frum. I thought we were not allowed to board a cruise that sails on a Friday (or Thursday, or Wednesday, for that matter). Any one knows how to explain this? Reply

Cruises from Israel I would like to consult you about travelling on cruise ships on Shabbat.

We recently went on a kosher cruise to Greece on a Mano Line ship, organized by AACI.

The ship did not leave Israel on Shabbat but travelled on Shabbat.

The ships is not owned by Mano but rented from a Panama based company.

The cabin and dining room staff are Asian and we were told that the ship's crew was comprised of non-Jewish Russians, thus overcoming the problem of operation of the ship on Shabbat by Jews.

We booked a subsequent cruise but then an announcement was circulated by the Israeli Chief Rabbinate claiming the Kashrut supervison was inadequate and travelling involved Chillul Shabbat.

On personal clarification with David London, the manager of AACI, I was satisfied as to the stringent Kashrut supervision. However when I queried the crew operation of the ship on Shabbat, he told me that some of the crew were Jewish.

Therefore I cancelled the cruise. Reply

Leaving 3 days before Shabbos How would this apply to a cruise which leaves on Sunday, makes several port calls, and is at sea on Shabbos, where the initial boarding is more than 3 days before Shabbos, but the last port calls are less than 3 days before Shabbos? Reply

getting off at a port Assuming that you are not carrying anything and are careful about the techum, you can go out and explore the port. Reply

Anonymous London, U.K. July 25, 2010

cruise If the ship stops at a port on a Shabbat, is it permissible to get off and explore the port? Reply

Gershon the Talmid July 16, 2010

Meals I once asked a rav about this, and he told me that it was not okay. One problem is that the rule of ain bishul achar bishul does not apply if there is any liquid being warmed up. Reply

Yehuda Yesodot, Israel July 15, 2010

Shabbos Cruising regarding meals I am under the impression that the pre-packaged food is "pre-cooked" and therefore the kitchen staff on the ship is warming it in a microwave oven.

Is it permissible if we do not ASK for it to be warmed up or reheated (ain bishel achar bishel)? Is this food okay to eat on Shabbos? Reply

Menachem Posner for May 22, 2009

to Chaim There are indeed many parallels between ships and planes. However, there are some very big differences which rule out air travel on Shabbat. One of them is the fact that very few (if any) flights last long enough for you to board before Shabbat and remain there until after Shabbat. Another difference is the fact that even a docked ship floats many feet above the seabed making techumin less problematic than that of an airplane which rests on the earth. Reply

Chaim Zighelboim Eau Claire, WI May 17, 2009

Shabbat Travel How is it permissible to travel on a cruise on Shabbat, but not on an airplane? What's the difference? Even if one boards 4 days prior, it still stops and goes every day/two days from one port to another. Reply

Thank you for the Jewish cruise advice!!!!! I never thought that existed!! Reply

Cruising. Our Rabbi was most helpful in helping us, since we've adopted a more observant lifestyle, to navigate about the ship. Reply
