Starlink on a Boat: Mounting, Power and Plans
What to know before installing Starlink on a boat or yacht: mount location, sealing, power, plans and typical marine installation costs.
Boats are one of the most common reasons owners hire a pro. Salt, vibration and motion are hard on hardware, and a leaking deck penetration is costly.
Mount location
Mount high with a clear view of the sky, away from radar beams, antennas and rigging shadows. On sailboats, stern arches or radar poles are common; on powerboats, hardtops and arches.
Sealing and hardware
Use 316 stainless or marine-grade mounts and a sealed cable gland, never an open hole with sealant alone.
Power
Many setups run from the boat's DC system through a converter, which avoids inverter losses. Size the battery bank and wiring with proper fusing.
Plans
Use offshore or in motion usually needs a plan the provider allows for maritime use. Check the provider's current terms.
Typical cost
From about $750 for a standard mount; $1,000–$2,500 for high-performance terminals; yacht network integration from $1,395+.
Frequently asked questions
Can I use a home dish on my boat?
Hardware and plan rules change. Confirm with the provider whether your hardware and plan are allowed for use on the water.
Will it interfere with my radar?
Mount it outside the radar beam path. A marine installer will check placement.
