Fleet One

Fleet One is specifically designed to meet the low data usage demands of occasional or seasonal users when they move out of VHF or GSM coverage areas. Inmarsat now offers two service plans to put satellite broadband in the reach of any size of commercial or leisure vessel.

Standard IP data

Always-on IP data service up to 100kbps for email and internet access, and applications including real-time electronic charts and weather reporting.

Satellite telephony

One voice line for crystal clear calls, plus SMS up to 160 characters.

Multi-user capability

An optional wireless router supports multiple users via smart devices and laptops.

Fleet One Coastal

With Fleet One Coastal, recreational sailors and small regional fishing boat operators can access tailored airtime pricing in key coastal regions to keep costs down.

The service is aimed at occasional users looking to stay connected without having to worry about cellular coverage or network roaming charges. Competitive rates are available for prepaid use – ideal for one-off trips.

Fleet One Coastal is available to vessels under 500 gross tonnage. Typical users are small fishing and leisure boats up to 24 metres.

Fleet One Global

Fleet One Global offers flexible connectivity for any size of vessel, available for one price anywhere on the world’s seas.

Fleet One Global meets the voice and data needs of a wide range of users, from fishing and regional merchant vessels to global recreational seafarers. There is no vessel size limit.

There is one global rate and a choice of prepaid or postpaid options. Fleet One Global is flexible – you can de-activate and re-activate the service at any time so you only pay for it when you need it – making it ideal for both seasonal and regular users.
