 Starlink Maritime Service Plans


  • In Motion 50GB priority access data
  • In Motion 1TB priority access data
  • In Motion 5TB priority access data

Mobility service plans will no longer be bitrate limited to 1 Mbps download and 1 Mbps upload after
surpassing the allocated Priority Access data threshold. Depending on the service location, the following
behavior will apply:
For Mobility service plans being operated on land or inland waters, Starlink users will receive unlimited
Basic Access data after surpassing the allocated Priority Access data threshold.
For Mobility service plans being operated in international waters, Starlink users will not have Internet
access and need to reach Castor Marine via other means to buy additional Priority Access data.
Priority Access data is giving network priority over Residential Priority Access on the Starlink network. Users
with Basic Access may experience slower speeds and reduced performance compared to Priority Access
in times of network congestion. See Starlink Specifications for details on Starlink's expected performance
per Service Plan.
