Staying connected on board: Wi-Fi, SIM card, and remote work

What are the options for staying connected on board?

To keep a connection during your cruise, several options complement each other depending on your usage, your destination and your boat. No single option works everywhere: your best bet is usually to combine two. The table below summarizes the most common options, with their strengths and their limits.

Is there Wi-Fi on board charter boats?

No, not always. Wi-Fi is not standard equipment on a charter boat, unlike a hotel or a vacation rental. Whether it is available depends on the boat, the fleet and the home base. When it exists, it usually takes the form of a mobile device, a 4G router installed on board, which picks up the cellular network and rebroadcasts it as Wi-Fi on board.

In practice, the quality of this Wi-Fi depends directly on the cellular coverage of the area where you are sailing. Close to the coast and in harbors, the signal is generally good. Offshore, in a secluded cove or on a faraway destination, it can weaken or even disappear. It is a convenience for light use, not a fiber connection. The boat's details and your quote state whether the Wi-Fi is included, offered as an option or absent.

How do you get online on a boat?

Beyond onboard Wi-Fi, several options will keep you reachable. The right choice depends on your destination and how intensively you use it.

The boat's Wi-Fi (4G router)

This is the simplest route when it is available: the charter company provides a preconfigured router and you connect just as you would at home. Useful for a crew sharing a single connection, but the speed stays modest, often a few megabits shared between everyone: fine for messaging and weather, just about enough for video calls. Book it in advance, as the number of routers per base is limited.

The local SIM card or eSIM

For sailing outside the EU, a local SIM card or eSIM bought before you leave is typically the most cost-effective way to stay connected on a charter boat. An eSIM is a digital SIM card, activated remotely with no physical chip, that you set up directly from your smartphone. You then have your own cellular connection, which you can share with the rest of the crew via tethering. Check that your phone supports eSIM and which carrier has the best coverage in the area you are heading for. In some countries outside the EU, a local SIM card also has to be registered against your passport.

Your cell phone plan and roaming

On a U.S. cell phone plan, international roaming is not automatic and is usually charged separately. Major carriers offer an international day pass (often around $10 to $12 a day) or plans that include slower international data; some prepaid plans charge full rates abroad. Before a Mediterranean cruise, check your carrier's international options: for a week or more, a local SIM card or eSIM is often cheaper than daily roaming. And turn off data roaming when you don't need it, to avoid a surprise bill when you get home.

One important point at sea: as soon as your phone connects, far from shore, to a ship-based cellular network carried by satellite (often labeled "Cellular at Sea" or similar), that connection falls outside your normal roaming plan and can be very expensive. Set network selection to manual or switch cellular data off when you don't need a connection.

Tethering from your phone

The hotspot feature (tethering) turns your smartphone into a Wi-Fi access point for your other devices. Free and always available, it suits occasional use. In return it drains the battery and your plan's data, which is why it is worth planning to recharge on board.

Starlink, satellite internet

Starlink satellite internet provides reliable connectivity beyond 15 to 20 nautical miles from shore, where 4G coverage typically ends. That makes it the best option for offshore sailing or intensive remote work, and some clients now ask for it explicitly. A few newer boats and some crewed yachts are now fitted with it. When it is offered as an option, the charter company charges for it, and the cost can run to several hundred euros for the charter period. This technology is not yet widespread across charter fleets: its availability and price are best checked boat by boat with our team.

How much does onboard Wi-Fi cost, and is it paid?

Wi-Fi on a charter boat usually costs between €30 and €250 (roughly $35 to $275) for the whole charter period, depending on the charter company and the package. That range applies to the 4G router; Starlink is charged separately, from several hundred euros (see below). For example, Wi-Fi paid to the captain on board is around thirty euros, while a high-speed option with a large charter company can approach €250. At some bases or in seasonal promotions the Wi-Fi is occasionally free, but that is the exception rather than the rule.

This fee is paid, depending on the situation, at the time of booking, at the base during check-in, or directly on board with the skipper or captain, sometimes in cash. An important point to watch: the charter company's contract may list a Wi-Fi option that does not appear on your Filovent quote. So check both documents and, if in doubt, ask our experts whether the Wi-Fi is included, optional and at what price, so you can build it into your budget rather than discover it once you are there.

Is cellular coverage good at sea?

Close to the coast, cellular coverage is generally good, especially in the European Mediterranean, where the network of cell towers is dense. You pick up a signal in most harbors, marinas and anchorages near the shore. This is the comfort zone for onboard Wi-Fi, which relies precisely on this cellular network.

In the Mediterranean, the network generally reaches up to around 15 nautical miles from the coast; beyond that, the signal becomes unpredictable and can drop out. Offshore, between two islands or in a steep-sided cove, the connection weakens, and on faraway destinations it depends heavily on the local carrier and the area. For offshore sailing or a need for a constant connection, only satellite, such as Starlink, offers genuine continuity.

Is there Wi-Fi on a charter catamaran?

Charter catamarans often have no Wi-Fi on board. It is not included as standard and, especially within the large managed fleets, it is frequently not even offered as an option. So it is best to assume there is none, and to check it on the boat's details rather than take it for granted.

If you opt for a catamaran charter and a connection matters to you, the safest approach is to arrange your own cell phone plan or a local SIM card, shared via tethering with the rest of the crew. Ask your advisor to confirm before booking, especially if you intend to work on board.

Can you work remotely from a boat?

Yes, working remotely from a charter boat is possible, as long as you plan ahead and choose the right setting. A reliable connection is not something you improvise on board. Prep before you leave: match your destination, boat, and connection options to what your work actually needs. Here are the habits to adopt:

1. Choose a coastal sailing area with good cellular coverage, rather than an offshore or very remote itinerary.
2. Arrange a main option and a backup: for example the boat's Wi-Fi plus a SIM card, so you do not depend on a single network.
3. Plan ahead for power to charge your laptop and phone, under way or once connected at the dock.
4. Schedule your video calls for the windows at the dock or at anchor, when the boat is steady and the connection is at its best.
5. Consider a skippered charter to free yourself from sailing and keep time to work, or a boat fitted with Starlink if a constant connection is essential.

With this framework, alternating between work and sailing becomes realistic for everyday office tasks. For critical video calls or large file transfers, plan for a satellite option and schedule important appointments for the windows at the dock.

How do you charge your devices on board?

On board, electricity comes from the boat's batteries, recharged by the engine under way and from the dock when you are connected in port. You generally have 12-volt outlets and USB ports, and some boats offer 220-volt (European-style) power via an inverter or once connected to the dock's shore-power pedestal. To understand it all, see our article on the sources of electricity on a boat.

For remote work, two precautions are sensible: bring good-capacity power banks for your devices and limit very power-hungry uses when the boat is at anchor with the engine off. Charging under way or at the dock remains the safest way to set off with your devices full.

What about a cabin cruise or a crewed boat?

A cabin cruise (also called a cabin charter or shared sailing trip) lets you book individual cabins on a crewed boat, sharing the vessel with other guests. On this kind of trip, or on a private crewed boat, the logic is different: the connection is often part of the onboard services, and a growing number of vessels are fitted with Wi-Fi, or even Starlink. Availability and quality vary from one boat to another, though, particularly on faraway destinations where the connection may be limited to ports of call.

One point to know on crewed boats: connection costs, such as adding data or Wi-Fi during the trip, are sometimes settled through the APA, the onboard fund used to cover shared expenses (fuel, harbor and transit fees, provisioning). They then appear in the final APA reckoning and not on your initial invoice, which can come as a surprise if you are not expecting it. Ask the crew at the start of the trip how the connection is billed.

As with everything else, your trip documents set out what is included on board. If the connection is an important criterion for you, flag it at the time of booking: our advisors can steer your choice toward a boat or a crewed sailboat charter that is properly equipped.

What internet is there for a Nile cruise?

On a Nile cruise, on board a dahabeya (a traditional Egyptian sailing boat), Wi-Fi is usually available but paid: it is often paid directly to the captain on board, typically around thirty euros for the whole stay. Cellular coverage along the Nile is reasonable near towns and sites, spottier between ports of call.

For these destinations, Filovent offers a prepaid SIM card as an extra, a good way to have your own connection without depending on the ship's Wi-Fi. In Egypt, a local SIM card is registered against your passport. If Egypt is your destination, ask our concierge team for the details of this option and its price when you book.

Is there internet on board a penichette?

On a river cruise this question comes up often, because the penichette, a canal boat for river cruising, travels slowly, at the pace of the water and very close to the banks. Cellular coverage is generally good along inhabited canals and rivers, which makes sharing a connection by smartphone particularly suitable. We go into this in detail in our dedicated article on internet on board a penichette.

What connection costs should you budget for?

Connection costs are manageable for most users and vary by option:

1. The boat's Wi-Fi: an option charged as a flat fee for the charter period, generally €30 to €250 depending on the charter company and the package, sometimes free.
2. The local SIM card or data eSIM: the price depends on the country and the data allowance you choose, paid by you.
3. Your cell phone plan: check your carrier's international roaming, often an added daily pass, since it is not included by default abroad.
4. Starlink: when it is offered as an option, the charter company charges for it, sometimes several hundred euros for the charter period.

For a cruise on a crewed catamaran, the shared Wi-Fi router is often the most practical option. For a trip solo or as a couple outside Europe, a local SIM card is frequently the most economical.

How can you stay connected without surprises?

To set off on your cruise connected and relaxed, keep these points in mind:

1. Check the boat's details and your quote to see whether a connection is included, optional or absent.
2. Match your option to the destination: cell phone plan in Europe, local SIM card or eSIM elsewhere, satellite for offshore.
3. Arrange a backup network if you need to stay reachable, rather than depend on a single access point.
4. Plan ahead for charging your devices and bring power banks.
5. Book the boat's Wi-Fi in advance, as the routers available per base are limited in number.
6. If in doubt, ask your Filovent advisor about the connection options on the specific boat you are interested in.
