Wifi on a Yacht Charter: Starlink, 4G and Roaming
Yes, most charter yachts can get you online, but how well depends on the boat. Starlink satellite internet has become standard on many luxury and crewed yachts and works far from land. Most bareboat yachts rely on a 4G/5G router with a local SIM, sometimes as a paid extra with a data cap. Near the coast your own phone with EU roaming also works.
Updated: 25 September 2026. Plans and equipment change often, so confirm what your boat has with the charter company before you travel.
What are the options for internet on a charter yacht?
There are three ways to get online on a week's charter in the Mediterranean, and many boats combine two of them:
- Starlink satellite internet built into the boat, with a wifi network for guests
- A 4G/5G router with a local SIM card that shares the mobile network over wifi
- Your own phone, using EU roaming or a local SIM, and sharing it as a hotspot
| Option | Coverage | Speed | Typical cost | Where common |
|---|---|---|---|---|
| Starlink | Near shore and far from land | Fast, like home broadband | Included on many crewed yachts | Crewed and luxury yachts, bigger catamarans |
| 4G/5G router | Only where there is mobile signal | Good near towns, weak in remote bays | Included or paid extra, often with a data cap | Bareboat sailboats and catamarans |
| Own phone (EU roaming) | Only where there is mobile signal | As on land, when there is signal | Your home plan, if the fair-use limit allows | Everyone, as a backup |
| Ship or satellite network on your phone | At sea | Slow | Very expensive, no EU price cap | Avoid |
Starlink on yachts: how it works and why it changed charter
Starlink is a network of thousands of satellites in low orbit, about 550 km up. Older maritime satellite systems used satellites around 36,000 km away, which made them slow and costly. Starlink's low orbit gives a delay of roughly 25 ms instead of 600 ms or more, so video calls and streaming work normally.
A flat antenna on deck talks to the satellites, and the boat's router hands out a normal wifi network. Because it doesn't need a mobile mast, it keeps working in the empty bays between islands where 4G drops out.
For boats, Starlink sells Roam plans, which cover coastal waters up to 12 nautical miles from shore, and Starlink Maritime on Global Priority plans (formerly Mobile Priority) for the open sea. Priority plans come with a data allowance. When it runs out, speed drops to about 1 Mbit/s, which is still fine for messages but not for video.
This is why connectivity went from a luxury to something charter guests expect. Starlink has become standard on many luxury and crewed yachts, and more and more bigger catamarans have it too. If you browse crewed yachts in Greece or crewed yachts in Croatia, ask whether the boat has Starlink and whether there is a data limit for guests.
4G/5G router with a local SIM: the bareboat standard
On most bareboat sailboats and catamarans, wifi means a small 4G or 5G router with a local SIM card. It works well in harbours, in town bays and along most of the coast. It gets weak or disappears in remote anchorages behind hills, on the open crossing between islands and far from the mainland.
Some charter companies include the router in the price. Others rent it out as an extra for the week, sometimes with a fixed amount of data. A group of six streaming films every night can use up a small allowance in a couple of days, so ask how much data is included and whether you can top up.
Can I use my own phone on a yacht charter?
Yes. Croatia, Greece, Italy, Spain and France are all in the EU, so "roam like at home" applies. Customers with a plan from an EU or EEA country, Norway included, pay their home price when connected to a land-based mobile network. That covers most of the time you spend in harbours and along the coast.
Two things to check before you leave:
- Fair use: operators may limit how much data you can use abroad at your home price. Check your plan's limit.
- Hotspot: sharing your phone's data with a laptop usually works, but it eats data quickly.
A local prepaid SIM or an eSIM bought for the country is a simple extra option if your home plan has a low limit abroad.
The maritime roaming trap: how to avoid a huge phone bill
EU roaming rules only apply on land-based mobile networks. At sea, a phone can connect to a ship's or satellite mobile network instead. The EU says plainly that the rules no longer apply there and charges are not capped. A few minutes of data can cost a lot.
This happens on ferries and on some yachts, and it can happen when the land signal is weak. Under EU rules your operator should send you a free text message when you connect to such a network. Take that message seriously.
How to avoid it:
- Choose the network manually in your phone settings instead of automatic, so it only picks a normal local network.
- Turn off data roaming, or use flight mode with wifi on, when you are far from land or on a ferry.
- Near Dubrovnik (Montenegro), Corfu (Albania) and the Dodecanese islands (Turkey), your phone can pick up a non-EU network. EU roaming doesn't apply there, so check which network you are on.
- Use the boat's wifi for anything heavy, such as updates, backups and video.
How do I know if a boat has wifi?
Start with the listing. On Ship O'Hoi, charter listings show the boat's equipment, and "Wi-Fi & internet" is one of the items. The equipment list doesn't always say what kind of internet it is, so ask the charter company:
- Is it Starlink or a 4G/5G router?
- Is it included, or an extra with a weekly price?
- Is there a data limit, and can we buy more?
- Does it work at anchor, or only in port?
On a crewed charter you can also mention it in the preference sheet, especially if someone needs to work.
What limits should I expect?
Even good wifi on a boat is shared by up to 8–12 people. Expect these limits:
- Data caps: common on routers, and possible on Starlink plans too
- Streaming: fine on Starlink, but on 4G several HD streams at once can slow everything down
- Coverage gaps: routers lose signal between islands and in remote bays
- Power: on a sailboat without a generator, the crew or skipper may switch wifi off at night to save the batteries
Tips for working remotely on a yacht charter
A week on a boat can include some work if you plan for it:
- Choose a boat with Starlink if calls matter. Browse yachts for charter or catamarans for charter, then ask about the internet.
- Put important calls on harbour days, when both wifi and mobile signal are strongest.
- Download files, maps and playlists in port.
- Bring a power bank and a 12 V or USB-C charger; our yacht charter packing list has the details.
- Tell the skipper about fixed meeting times so the route can put you at anchor, not under sail, at that hour.
Still choosing where to go? Coastal routes with many towns give the best mobile coverage. See boats for rent in Croatia or our guide to the best Mediterranean charter destinations.
FAQ
Is wifi free on a yacht charter?
Sometimes. On many crewed yachts internet is part of the package. On bareboat yachts the router is often a paid extra. The listing and the charter company will tell you.
Does Starlink work while sailing?
Yes, when the boat has a plan that allows use in motion. Roam plans cover coastal waters, while Global Priority plans also cover the open sea. Speed can drop if the antenna is shaded by the mast or sails.
Can I stream Netflix on a yacht?
On Starlink, usually yes. On a 4G router it depends on the signal and on the data allowance, so download films in harbour to be safe.
Will my phone work between the Greek islands?
Mostly, but there are gaps on longer crossings. When there is no land signal, keep data roaming off so the phone doesn't connect to an expensive ship or satellite network.
Can I bring my own travel router?
Yes, a travel router or a mobile hotspot with a local SIM works on any boat. It depends on the same mobile coverage as the boat's own 4G router.
