Connectivity at sea used to mean expensive sat-phone data. Starlink Mini changes that for trawlers, yachts, and work vessels — but a boat is the harshest environment a dish will face: salt, spray, vibration, and a moving horizon. This guide covers a marine-ready Starlink setup with PLZTECH hardware.

1. Mounting on a moving platform

The Starlink Mini magnetic roof mount for yacht/RV is the starting point: marine-grade materials and strong magnets hold through spray and motion. For vessels with rails, the universal pipe clamp mount (20–60 mm) clamps to a rail or antenna pole. A suction-cup roof mount works for temporary installs but isn't for sustained offshore use.

Stability matters: Starlink needs a clear sky view. On a vessel with a gyro stabilizer or a steadying sail, the dish stays locked longer. Mount high and clear of the radar arch and mast clutter.

2. Power at sea

Boats run 12 V (or 24 V) house banks. Use the 12V→30V step-up for the Mini, or connect a LiFePO4 / house battery via the DC→Anderson plug cable for all-day operation. The 2-in-1 LED power bank (30 V) is a compact backup for tenders and emergency comms.

3. Weatherproofing

• Waterproof Starlink Mini case for stowage when not in use.

• Silicone protective cover for scratch and spray protection during operation.

• Seal every cable penetration with a marine-grade gland. The 2-in-1 combined cable keeps roof penetrations to one.

4. Extending coverage below deck

A single dish on the roof won't reach the cabin. Add an outdoor WiFi 6 access point (600 m IP67 unit) wired from the Starlink router to broadcast below deck and to the cockpit. For linking to a shore base or another vessel kilometers away, use a 5.8 GHz wireless bridge (3/5/25 km).

6. Safety & regs

• Keep the dish clear of the compass and VHF antennas.

• Don't mount where it becomes a snag hazard in rough seas.

• For offshore beyond cell range, pair Starlink with a backup sat device.
