The Boater’s Installation Guide

3.1 Mounting Solutions for Every Vessel

The Critical Sky View Requirement

Starlink must be 100% unobstructed for best performance. Even small obstructions in the field of view will have a negative impact on the quality of the connection… Each dish should have clear view of the sky from around 20° elevation (above the horizon), with a full 360° azimuth (rotation).

Popular Mounting Options:

• Pole mounts on stern or bow pulpits
• Mast mounts for sailboats (consider obstruction from sails)
• Hardtop installations on powerboats
• Custom fabricated solutions for unique vessel configurations

Customers have been successful installing Starlink on masts, railings, elevated posts, and roofs, since the dishes are less likely to be obstructed. The key is finding a location that maintains that crucial view of the sky while being accessible for maintenance.

Real-World Installation Tips:

• Use the Starlink app to verify clear sky view before final installation
• Consider seasonal variations – will rigging or canvas block the signal?
• Plan for cable routing to protect from weather and foot traffic
• Test temporarily before permanent mounting

3.2 Power Considerations: Managing Consumption

In our experience, the Starlink draws about 6ah. About what a small fridge requires. Understanding power consumption helps you plan your electrical system properly.

Power Requirements:

• Standard dish: 25-60 watts average (120 watts maximum)
• High Performance dish: Similar consumption but with DC power option
• Starlink Mini: Lower power consumption, DC power input for ultimate efficiency

Power Supply Options:

1. Use onboard inverter – Most common approach for recreational boats
2. DC conversion kits – Third-party solutions for direct 12V/24V operation
3. Dedicated marine power supplies – Purpose-built for boat installations

It is recommended to power the Starlink and any downstream router from a power source protected by an Uninterruptable Power Supply (UPS) to protect against voltage spikes common in marine electrical systems.

3.3 Network Integration Strategies

Option 1: Use Starlink Router We recommend using the Starlink router for initial setup confirmation. This approach works well for simple installations where Starlink is your primary internet source.

Option 2: Integrate with Existing Marine Network Many boaters prefer connecting Starlink to their existing network infrastructure:
