How long does it take to install Starlink on a fishing boat?

Between one and one and a half days of effective work on most fishing vessels. On distant-water boats with long cable runs or where several bulkheads have to be crossed, it can stretch to two days. The figure that matters to the owner is not that one, but whether the work can be fitted into an already scheduled stop — unloading, gear change, survey — rather than generating additional downtime.

What should the quote include besides the Starlink equipment?

A reinforced marinised mount sized for continuous vibration, marine-grade glands, polyurethane or polysulphide sealant (never silicone), A4 stainless fasteners, a backing plate or corrosion treatment of the penetration depending on the deck material, cable fixings every 30 cm and mechanical cable protection in working deck areas. If the quote just says "installation" with no material breakdown, ask for the breakdown so you can compare offers.

Is the VMS checked after installing Starlink?

It must be checked, and it must be recorded in writing. A professional installation on a fishing vessel records VMS status before starting and checks it again on completion, documenting both with date and time. Without that prior record, if a problem appears afterwards there is no way to determine whether the installation caused it. If the VMS is also moving to transmit over IP via Starlink, the configuration must be verified with the approved VMS provider.

What documentation do I need to keep for insurance purposes?

Photographs of every deck penetration before sealing, a record of VMS status before and after with date and time, a dated speed test, a screenshot of the obstruction check, a diagram of the cable route and electrical connection point, and a signed handover record stating the scope of the workmanship guarantee. Insurers ask who carried out the work and with which materials in the event of any claim related to the equipment or to water ingress through the deck.

What a professional Starlink installation on a fishing vessel includes

“Installation included” means very different things depending on who says it. For some it is bolting on a mount and running a cable. For others it is a job with a pre-installation survey, specified materials, verification that the VMS is still transmitting, and signed documentation that stands up with the insurer.

The difference is not apparent on handover day. It becomes apparent in the second season, or the day a claim has to be filed. This article breaks down what a professional installation on a working boat should actually include, so you can read a quote and know what you are being sold.

Stage 1: pre-installation survey

Everything depends on this stage, and it is exactly what gets skipped by anyone giving a fixed price over the phone.

A serious survey on a fishing vessel checks six points:

Antenna position. Finding a flat spot is not enough. Sky visibility has to be verified from around 25° above the horizon across the whole arc the satellites travel, identifying what obstructs it: the mast, the superstructure, the gantries, the winches. On a working boat you also have to allow for the fact that the deck is used: the antenna cannot sit where it will take knocks from gear or boxes.

Coexistence with the VMS. This is the critical point and the one that distinguishes an integrator with fishing experience. Where the VMS antenna sits has to be documented, along with the separation to be maintained and how transmission will be verified on completion.

Cable route. From the antenna to the bridge. This is where surprises appear: bulkheads that have to be penetrated, conduits already full, engine spaces best not routed through.

Existing routes. Before drilling anything, a professional checks whether an existing penetration from other electronics can be used. On boats with previous refits there usually is one.

Electrical capacity. The Flat High Performance terminal draws between 40 and 75 W in normal operation, with peaks above 100 W. On a fishing vessel with a generator this is rarely a problem, but the protection and connection point have to be confirmed.

Fit with the calendar. The question that saves the most money: can it be done during a stop already planned?

This should produce a quote with a defined position, a defined route and listed materials. If it does not say where the antenna is going, the survey was not done.

Stage 2: materials

This is the line item cut when someone wants to be the cheapest. The Starlink equipment costs what it costs; the installation materials admit cheapening, and that is where durability is compromised in an environment that does not forgive.

Material	Why it matters on a working boat
Reinforced marinised mount	The kit’s is domestic. Here you need A4 stainless or marine aluminium sized for continuous vibration
Marine-grade gland	Sized to the cable. It is where water gets in if you skimp
Polyurethane or polysulphide sealant	Never silicone. It does not adhere reliably and ruins any later repair
A4 stainless fasteners	A2 pits in a permanently salt environment
Backing plate	Mandatory on sandwich. On steel, corrosion treatment of the penetration
Fixings every 30 cm	Without these the cable chafes and fails on a trip, which is the worst time
Mechanical cable protection	In working deck areas the cable needs protecting

If the quote is one line reading “installation” and a figure, ask for the breakdown. Without it you cannot compare two offers.

Stage 3: execution

Order matters and an integrator with the trade observes it:

Setting out and marking the final position and every drilling point, before the drill comes out. With the skipper or owner present where possible.
Recording VMS status before starting. Check and record that it is transmitting correctly. Without this prior record, if a problem appears afterwards there is no way to know whether the installation caused it.
Drilling and fitting glands, bedded in sealant with reinforcement or treatment according to the deck material.
Fixing the mount, with stainless fasteners and sealing at every penetration.
Running and securing the cable, at 30 cm intervals maximum, with mechanical protection in working areas.
Electrical connection of the router with its protection, in a dry, ventilated space on the bridge. Never on deck, never in a sealed locker with no circulation.
First boot and satellite acquisition, requiring between 5 and 15 minutes.

Stage 4: acceptance testing

This is where a professional installation separates itself from a fitting job. Before signing off:

VMS verification. First and most important. Confirm it is still transmitting correctly and record it in writing. If the VMS is moving to transmit over IP via Starlink, the configuration also has to be verified with the approved provider.

Speed test, download and upload, with the result recorded. That is your baseline: if performance drops in six months, you have something to compare against.

Obstruction check. The Starlink app maps what the antenna perceives. It should come back clean or, if there is residual obstruction, identified and justified. It takes a few minutes and is the verification most often omitted.

Watertightness. A hose over every penetration and a check from inside.

Electromagnetic coexistence. With radar running, VHF transmitting and AIS active, confirm everything holds its performance. And the reverse.

Coverage aboard, verified on the bridge, in the mess and in the crew cabins, which is where it will be used.

Stage 5: documentation

This is not paperwork: on a working boat it is what protects you with the insurer and in an inspection.

Photographs of every deck penetration before sealing. The only evidence of how what is now covered was executed.
VMS record before and after, with date and time.
Dated speed test.
Screenshot of the obstruction check.
Diagram of the cable route and the electrical connection point.
Signed handover record, with the scope and term of the workmanship guarantee.

Keep it aboard and in the cloud. We develop why this is decisive in our article on warranty and support.

What is usually NOT included

For transparency, what normally falls outside and has to be agreed separately:

Reconfiguring the VMS to transmit over IP (requires coordination with the approved provider)
Integration with chartplotter, sounder or fleet management systems
Separate networks for operations and for crew
Additional repeaters on boats with substantial steel bulkheading
Increasing electrical capacity

None is a rip-off extra: they are different jobs. What is unacceptable is for them to appear as a surprise halfway through the day, with the boat already tied up.

On fleet installations

Where several vessels are involved it is worth standardising hardware and configuration: it simplifies support, allows common spares, and means any skipper can operate the system even when moving between boats. And document each vessel separately, even where the configuration is identical.

How we approach it

At PescaSat we coordinate the installation with a certified naval communications integrator. What we add is making sure the quote arrives with all of the above itemised before anyone steps aboard, that VMS verification and documentation are in scope from the start, and that the work is scheduled to fit your operational calendar.

The assessment is free and the final price is the same as going direct.
