Updated on 13 August 2026. Starlink Mini is a compact terminal with an integrated Wi-Fi router. It may suit some boats, but the choice is not just about throughput: you must check the service plan, navigation area, sky view, power supply, mounting and expected continuity level.
The short answer
The Mini is relevant when compactness and low power consumption are the priorities. Starlink states an average power draw of 25 to 40 W, a 12–48 V DC input limited to 60 W, a weight of about 1.10 kg and an IP67 rating when the power cable and Starlink connector are correctly installed. These specs do not exempt you from a proper wiring, protection and mounting study adapted to the boat.
Characteristics to verify on the official sheet
| Item | Manufacturer data | Consequences aboard |
|---|---|---|
| Power supply | 12–48 V DC, 60 W max. | Size wiring, protection and converter according to the boat’s network |
| Average power draw | 25–40 W | Include it in the energy budget and daily usage time |
| Router | Built-in Wi-Fi 5, one Starlink Ethernet port | Assess indoor coverage and connection to a shipboard router |
| Environment | IP67 with specified cables installed | Follow connectors, sealing, orientation and bend radius |
| Field of view | Phased-array antenna, 110° | Ensure clear sky view and limit rigging obstructions |
Reference: Starlink Mini official spec sheet. Starlink notes that using a standard RJ45 Ethernet cable changes the ingress protection rating; use accessories and instructions matching the exact generation.
Mini, Standard or Performance?
Starlink currently allows Mini, Standard and Performance terminals for certain mobile uses. For demanding maritime environments and areas with obstructions, Starlink recommends its Performance terminals, designed for mobility and offering a wider field of view. The right choice depends on the program:
- occasional use or removable installation: the Mini prioritizes compactness;
- permanent installation and enhanced continuity: consider a Performance terminal and its power supply;
- multi-user shipboard network: plan for Ethernet, router, segmentation and possibly a 4G/5G failover;
- professional use: check the plan, data priority, administration and need for a public IP address.
The plan is as important as the antenna
Compatible hardware does not guarantee that the plan allows the intended sailing. Starlink currently states that Roam plans include specific conditions in coastal waters and that an ocean mode or tailored plan is required for certain offshore uses. Names, limits and rates change. Check ocean-use conditions and the coverage map when subscribing, then again before an offshore passage.
Installation: five checks to avoid surprises
- Sky view: use the Starlink app and test obstructions from mast, boom, rigging and superstructures.
- Mounting: use a mount rated for the loads, vibrations and boat motion; secure removal if the antenna remains mobile.
- Wiring: follow manufacturer connectors, lengths, bend radii and sealing conditions.
- Power: calculate daily consumption based on hours of use, not just instantaneous power.
- Network: check Wi-Fi range inside the boat, especially on a metal hull, and use Ethernet if needed.
Throughput and latency: do not expect a single figure
Performance varies with location, congestion, plan, obstructions, weather and motion. A single measurement on a boat or at a given date is not a guarantee. For critical use, size the system to the minimum acceptable service, test the actual route and keep another communications channel.
Starlink is not a distress means
Starlink provides Internet access. It does not replace the mandatory VHF, an EPIRB, or a satellite terminal designed for voice or distress alerts. A bluewater setup separates Internet, shipboard communications and regulatory distress.
