Nowadays having a good internet connection on board will make you sail more smoothly. Near the coast, you can use your smartphone or tablet (which, by activating the “tethering” function, will share the connection with any other devices, such as laptops) or wifi antennas. With the emergence of the high-speed 4G network, performance similar to that of an ADSL line (50 to 100 Mbps on average) is achieved. And with 5G expected to go into service around 2020, the result will be comparable to fiber optics. But if you go a few miles away from the mainland, the signal weakens and disappears.

For long crossings, there are no alternatives to satellites (Iridium, Inmarsat, Thuraya), which are reliable but not the cheapest in terms of initial purchase and subscription. Things will not change, at least in the near future: operators of 4G (and soon 5G) networks have no interest in “covering” the sea, as the number of users remains relatively low and often confined to certain times of the year (summer) and week (weekends)…
