Satellite Internet at Sea: Hardware, Airtime, and Pricing 2024

Sailing the open sea can be the perfect place to get away from it all, but we all know how imperative it is to stay connected while doing so. We are a society that thrives off the ability to communicate to anyone, anywhere, and anytime. Though finding the right solution to get satellite internet for boats may be more challenging than securing it on land, the maritime options available are the best we have ever seen.

Satellite Internet for Boats

From small vessel to vast fleet, open sea adventures to large-scale shipping operations, connectivity is essential for day-to-day communication. This requires finding the right maritime satellite internet solution that integrates seamlessly with the needs you or your team require.

For the times that you are docked in the marina or within 5-10 miles offshore, you’ll be able to utilize a typical Wi-Fi connection or obtain a cell signal. But that won’t work when you get farther out to sea which is why satellite internet is a necessity. The other challenge when it comes to internet on a boat is finding a way to maintain the connection even when waves are constantly rocking the boat back and forth or weather becomes severe.

Maritime satellite internet with the proper device is what you will require.

Obtaining Satellite Internet for Your Boat

For those heading out on a short, offshore excursion seeking a way to obtain an internet connection for themselves, a device like the Iridium Go! fits the bill. This portable device turns your own smartphone or tablet into one that supports a range of satellite communication functionality. But it doesn’t account for the movement challenges that arise on a boat.

So for those spending days at sea who require a reliable and faster connection similar to what you’re used to back home, you’re going to need a more robust device designed specifically for the needs required of anyone operating at sea.

The capability of the maritime satellite internet terminals and the networks they operate on have come a long way. By choosing the right fit, you can ensure that you have all the capability you need whether that’s getting the kids on a video call with Grandma or closing an important business deal.

For the high-speed internet you can rely on (because who has time to wait), your choices come down to Global L-Band Broadband or Maritime VSAT. So what’s the difference?

MARITIME-SPECIFIC GLOBAL BROADBAND SATELLITE INTERNET DEVICE OPTIONS

There are extensive options available via global broadband satellite. Whether you choose a device that operates on the unmatched worldwide network of Iridium or the proven network of Inmarsat, you can be confident in staying connected no matter how long you’re on the ocean.
