Maritime communication is essential for ensuring seamless connectivity at sea, whether for commercial vessels, private yachts, or maritime operations. A stable and efficient connection allows for real-time navigation, emergency response, and onboard entertainment. Starlink has emerged as a revolutionary solution for maritime internet, offering reliable high-speed connectivity even in remote waters.
Understanding Obstructions and Signal Strength
For optimal maritime internet performance, the satellite dish must have an unobstructed view of the sky. The Starlink system detects obstructions automatically and generates a map to identify any interference. Users can check the obstructions directly from the Starlink interface and reposition the dish if needed. It may take up to 12 hours for a complete analysis.
Key Recommendations:
- Mount the dish in an area with a clear sky view.
- Avoid obstacles that block the satellite’s line of sight.
- Check the obstruction map regularly in the Starlink interface.
Maritime Communication: Connecting Starlink to Your Network
For those integrating Starlink internet into an existing maritime Wi-Fi network, an Ethernet connection is required. Simply connect the Starlink power supply to the WAN port of your router to extend coverage across the vessel.
Router Configuration:
- DHCP – Configure the router’s WAN port to obtain an IP address automatically.
- Health Checks – Set failure thresholds (e.g., 5 failed pings in 10 seconds) to tolerate occasional drops.

Starlink Hardware Protection Ratings
| Component | IP Rating | Protection Details |
|---|---|---|
| Starlink Dish | IP56 | Resistant to dust and powerful water jets |
| Power Supply | IP56 | Resistant to dust and powerful water jets |
| Wi-Fi Router | IP54 | Resistant to dust and splashing water |
Sealing Cable Connections
If your cable connection is exposed to significant amounts of water, we recommend using a sealant to prevent water damage. Only non-setting sealant, like dielectric grease, should be used around the seal.
No RTV should be placed on the seal, nor on the surface that interfaces with the seal, nor on the metal part of the connector. Once the cable has been fully inserted, then Dow 737 RTV can be used on the very outside of the socket/plug interface to provide additional waterproofing.
Maritime Communication: Cable Details
The Starlink cables are not reversible. In other words, the connector on the end of the cable is specific to the device it connects to. For example, be sure to route the cable with the dish end of the cable at the location of the dish, etc.
There is a MAXIMUM distance of 25 meters from the dish to the PSU. This is due to the voltage requirements at the dish. Do not attempt to extend the cable beyond 25 meters. We do not recommend cutting and splicing this cable. The total length from the dish to the network equipment is 100 meters.
| Cable Standards | Details |
|---|---|
| General Application | Indoor/Outdoor, Sunlight Resistant |
| Data Category | 5E |
| Flame Rating | UL: CMX Outdoor / CMR per NEC Article 800 under UL Category DUZX |
| UL Flammability | UL 1581 VW-1, UL 1666 Riser |
| CSA Flammability | FT1 |
| Temperature Rating | 105°C |
| Operating Temperature | -40°C to 105°C |
| Construction | 4 Twisted Pair |
| Compliance | RoHS, REACH |
Expanding Maritime Communication with Multiple Starlinks
Larger vessels or maritime businesses may require multiple Starlink units for enhanced marine connectivity. To ensure optimal performance:
- Maintain a minimum separation distance of 0.9 meters between dishes.
- Position antennas to have a clear 360° view above 20° elevation.
- Use a third-party router (such as the Marine Data Solutions MDS Blender) for load balancing, failover, and traffic management.
Maintaining a Reliable Maritime Internet Connection
Starlink hardware is designed for low-maintenance operation, but regular checks ensure optimal functionality:
- Keep the antenna free from salt or dust buildup.
- Use the Starlink interface to monitor obstruction percentages.
- Enable snow-melting features in colder regions to prevent accumulation.
Troubleshooting Common Issues
If you experience connectivity problems, follow these steps:
- Check local weather conditions, as heavy rain may impact signal strength.
- Inspect cable connections from the dish to the power supply and router.
- Ensure the power supply indicator light is on.
- If using a third-party router, test connectivity by directly connecting a laptop to Starlink.
- Use the Starlink Dashboard to check service status.
