Starlink on a fishing boat: the three cost items and what moves them

The most frequent question we receive from vessel owners is straightforward: how much does it cost and how long does it take to pay back?

This guide answers with the three cost items and what moves them; the exact figure for your fleet goes in the written comparison, not here. If the numbers do not work for your situation, we will tell you.

The components of Starlink Maritime cost

1. Hardware: the terminal

The three cost items by vessel type, with the matching plan, are in the Starlink for fishing vessels guide.

The Starlink terminal for maritime use is the Starlink Flat High Performance, designed specifically for moving applications, with automatic satellite tracking (electronic phased array).

Indicative hardware price (2025):

• Starlink Flat High Performance terminal: the fixed item, priced by the operator and the same for everyone
• Starlink router included in the kit
• Mounting accessories (required for marine installation): variable by mounting type

The terminal is a one-off investment. There is no annual renewal fee or forced upgrade cost.

2. Monthly service subscription

Starlink Maritime plans for vessel use (2025):

Prices are indicative and may vary. Confirmed during consultation.

For most offshore fishing vessels, the standard or global plan is sufficient. The high-priority plan is intended for vessels with very intensive data needs or fleets requiring performance guarantees.

3. Certified installation

Installation includes:

• Pre-installation assessment of the optimal mounting configuration for the vessel.
• Terminal mounting on mast or wheelhouse top.
• Cabling and router configuration.
• Network configuration (operational/crew welfare traffic separation).
• VMS and ERS integration if required.
• Port-side operational testing.
• Basic skipper training.

Installation is the only item that really varies, with the complexity of the mount and the port.

Total initial investment

What you are currently paying (cost baseline analysis)

To calculate real ROI, you need to know what you are currently spending. Typical ranges by vessel type:

Inshore vessel (under 12 metres)

• Basic satellite phone or maritime roaming
• VMS often not required formally

Offshore vessel (12–24 metres)

• Iridium or Thuraya
• Satellite VMS, on a separate contract
• Two monthly bills that stack up

Deep-sea vessel (over 24 metres)

• Voice/data satellite communications
• Satellite VMS, on a separate contract
• VSAT or additional communications, with a third provider
• Three monthly bills that stack up, and the highest of the three categories

Pull those invoices out and add them up before reading on: that number is half the equation, and it is the only half you already have.

Three indicative profiles (no figures: yours go in the comparison)

Profile 1: Offshore vessel with VMS/ERS obligations

Situation: 17-metre vessel, offshore trips, ERS mandatory, Iridium basic.

*Conservative estimate based on VMS transmission failure proceedings.

What changes: three line items become one. How much, with your invoices in front of us.

Profile 2: Standard offshore vessel

Situation: 20-metre vessel, 12-day trips, Iridium + satellite VMS.

What changes: three line items become one. How much, with your invoices in front of us.

Profile 3: Deep-sea or large trawler

Situation: 28-metre vessel, 20+ day trips, VSAT + Iridium + VMS.

What changes: three line items become one. How much, with your invoices in front of us.

The ROI that does not appear on spreadsheets

The calculations above are conservative because they do not include:

• Better catch price: negotiating landing price with real-time market data. In fisheries with high price volatility, a difference of £0.08–0.16/kg can mean thousands of pounds per trip.
• Reduced crew turnover: the cost of training and retaining a qualified crew member (estimated at £13,000–25,000/year in turnover costs).
• Fewer technical stoppages: remote fault diagnosis allows resolution without waiting for the next port.
• Better decision-making: access to real-time ocean weather data to optimise routes and fishing zones.

Is there a minimum contract period for Starlink Maritime plans?

Current Starlink Maritime plans generally do not have mandatory minimum contract periods, though this can vary by plan type. During the consultation we explain the exact terms of each plan so you can choose the option that best suits your operation.

Does the Starlink terminal work when the vessel is in port?

Yes. The terminal works in port just as at sea. Many vessel owners take advantage of days in port for software updates, data downloads and remote system diagnostics by the technical service.

Can I pause the Starlink plan when the vessel is laid up for several weeks?

Recurring plans can be paused in whole months — closed seasons, refits — against an annual allowance of paused days; not for odd days between trips. The pause shows on the next invoice.

Is financing available for the hardware?

We can advise on hardware financing options. European Maritime and Fisheries Fund (EMFF/EMFAF) grants for vessel modernisation may partly cover investment in communication and compliance systems in eligible member states.
