Inmarsat Fleet One

Inmarsat Fleet One brings broadband to small vessels

The launch of Fleet One from Inmarsat Maritime enables yacht and fishing boat owners to take advantage of broadband services previously only enjoyed by much larger vessels.

Accessing weather information and chart updates, staying in contact with loved-ones or keeping up with the news is now as simple to do at sea as on land.

On sailing holidays or extended fishing trips, the new Inmarsat Fleet One service ensures small vessel owners have uninterrupted and cost-effective access to the internet, and can send SMS messages and talk on the phone, anywhere in the world.

Fleet One offers data connectivity at up to 100kbps, a single voice line and SMS.

Reliable network

Fleet One is delivered over the world’s most advanced global broadband satellite network – relied on by the maritime industry across the seven seas.

“We have all become accustomed to having access to information as and when we need it,” said Frank Coles, President, Inmarsat Maritime."

Being at sea is a unique experience and conditions can change at the drop of a hat. This shouldn’t hamper your ability to remain connected to the world.

Great opportunity

With this new, simple solution you will have dependable connectivity whenever you need it. With Fleet One, yachts and fishing boats now have access to the same, robust and reliable technologies previously only available on much larger vessels, allowing them equally to take full advantage of online connectivity.

Fleet One is delivered through a compact 2.5kg (5.5lb) antenna, specially created for leisure and fishing vessels, which can be quickly and easily installed.

Safety SOS service

Fleet One also supports Inmarsat’s unique ‘505’ safety service, which in an emergency routes you directly to a Maritime Rescue Co-ordination Centre (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 is on its way.

Fleet One Coastal Coverage Map

Fleet One is a global service, however, the specific Fleet One tariff is only available in selected geographies (green areas on coverage map below). Roaming outside the Fleet One home region areas will have an impact on airtime prices. Please consult us for information with regards to airtime prices and specific coverage.

The special Fleet One tariff will apply to traffic originating within the Fleet one service area. Meaning, e.g. leisure sailors will be able to use the Fleet One tariff in the Mediterranean during summer and the Caribbean during winter with the same subscription. However, when crossing the Atlantic users will be outside a home region and roaming costs will apply.

Please note that a Fleet One SIM can only be used with a Fleet One terminal.
