Why Choose Sailor Fleet One?

Built by the same company behind the industry-leading Sailor FleetBroadband series of satellite terminals, the Fleet One adheres to the same quality of manufacturing with a more affordable price and ongoing airtime options.

The Sailor Fleet One enables satellite broadband connections up to 100kbps and simultaneous voice calling on a single line. Its compact size and lightweight antenna mean that installation is easy, even for small boats, and many owners are able to install the equipment themselves, without incurring the additional cost of hiring an installer.

Sailor Fleet One Marine Fishing Satellite Broadband


With its low airtime pricing available for most coastal fishing areas, the Fleet One is a great choice for fishing vessels. Ranging more than 100 miles offshore in many areas in the US will still allow for Fleet One’s inexpensive “Home Region” airtime and allow fishing fleets the capability to stay connected while out of the range of cellular and WiFi.

You don’t have to commit to a lengthy contract and there is ability to suspend outside of fishing seasons. Alternatively competitive rates are available on a pre-paid voucher with no commitment required. It makes global voice and data easily accessible enabling you to achieve greater operational efficiency and increase crew welfare while keeping the costs of communications affordable.

Sailor Fleet One Satellite Internet for Cruisers

Recreational Cruisers

For recreational cruisers, the Fleet One offers some of the most affordable satellite broadband connectivity on the planet. While in the “Home Region,” airtime pricing and data speeds allow for web-browsing, email, and social media updates – all allowing you to stay connected with those back home without breaking the bank.

Fleet One supports Inmarsat’s unique ‘505’ safety service, which in an emergency routes you directly to a MRCC. This means that in one phone call you can alert the safety services of your position and nature of distress, by reassuringly speaking to the Search and Rescue Services knowing that assistance will be sent.

Fleet One Airtime Options

Fleet One airtime offers some of the most affordable satellite airtime rates in the industry. Make sure to carefully check the coverage map for Fleet One airtime, as pricing varies widely between the “Home Region” and “Out of Region” zones.

Fleet One “Home Region” Coverage Map

The coverage area for Fleet One airtime is very important in assuring you are getting affordable airtime rates. On the following map, the green areas indicate “Home Region” airtime. “Out of Region” airtime is still available for the rest of the Inmarsat coverage map, but will be much more expensive than “Home Region” rates. Fleet One Coverage Map

Fleet One “Out Of Region” Coverage Map

When not in the “home region” for Fleet One airtime, you will fall into the general Inmarsat coverage map. The coverage area for Inmarsat airtime encompasses a large portion of the earth. Inmarsat’s satellites are geo-stationary above the earth’s equator and offer good coverage up to 70° latitude. Because the satellites are stationed above the equator, you may need to position your satellite phone’s antenna in the direction of the satellite from your location in order to get a signal.
