Starlink Maritime: Satellite Internet for Yachts & Ships 2026

Compiled and fact-checked by the Starlink News editorial desk. Published 19 September 2026.

This guide is built from SpaceX’s published Maritime specification sheet, pricing page and terms of service; IMO, FCC, MCA and AMSA documentation; published competitor specification sheets; and installation quotations and invoices supplied to the desk by owners, electricians and yards. Where a figure is a field observation, a reader-supplied number or a widely repeated community estimate rather than a manufacturer specification, the text says so at the point it appears. Our sourcing, review and corrections policy is published at Starlink News editorial standards.

Starlink Maritime is SpaceX’s low-Earth-orbit satellite internet tier for vessels underway: a $2,500 Flat High Performance terminal, monthly plans from $250 to $5,000, and field-reported throughput of 25–100 Mbps offshore rising toward 220 Mbps in dense coastal cells. Starlink availability at sea covers every ocean between approximately 72°N and 56°S on the current coverage map, and the service is supplementary rather than a certified safety system — no flag state treats it as GMDSS or SOLAS equipment.

That combination is why the service moved from novelty to default within four years of its July 2022 launch. A cargo ship that paid five figures a month for a few megabits of geostationary bandwidth can now buy a terabyte of priority data for $1,000. The trade-offs are polar availability, regulatory maturity, and a hardware installation that demands a real marine electrical plan rather than a cigarette-lighter adapter.

What Is Starlink Maritime and Which Vessels Qualify

Starlink Maritime is the service tier SpaceX sells for permanent installation on a moving vessel, with terms that permit operation in international waters and a data plan priced for continuous offshore use. It is a separate product from Starlink Residential, Starlink Business and Starlink Roam — different hardware, different pricing, different terms of service. Buying a consumer kit and taking it to sea is not the same purchase, and the coverage entitlement is not the same either.

Eligibility splits on tonnage and purpose. Pleasure craft and small commercial vessels under 300 gross tons order standard Maritime plans directly through the business portal. Larger tonnage — bulk carriers, container ships, cruise vessels, offshore support and floating production units — routes into an Enterprise consultation, where SpaceX quotes multi-terminal deployments, bonded links and shared bandwidth pools rather than a single subscription. SpaceX’s own regulatory filings name commercial shipping, cruise lines, fishing fleets and offshore platforms as the explicit target segments; superyachts were simply the first customers with the budget to be early adopters.

The distinction that trips people up is Roam versus Maritime. Roam is a land-mobility product, sold with consumer hardware, and it stops working once you are past the coastal cells. Maritime carries the ocean entitlement and the ruggedised terminal. The hardware lineage is the same family SpaceX pushes into emergency deployments, a pattern covered in Starlink in Disaster Relief: Hurricane and Conflict Zone Connectivity — designed for a fixed mount, a hostile environment and no on-site engineer.

Maritime Terminal Hardware: Flat High Performance Specs and Installation

Starlink’s published specification for the Flat High Performance terminal gives 575 mm × 511 mm × 70 mm and 6.2 kg without cable. It is an active phased array with electronic beam steering across a 140° field of view — nothing rotates, nothing gimbals, and there is no radome to replace. It is rated IP56 for water jets and dust, operates from −30 °C to +50 °C, and is designed to stay bolted to the deck through spray, sleet and heavy wind loading. The electronics steer the beam fast enough to track satellites while the hull rolls, which is what separates it from a legacy stabilised dish and why it survives on hulls where a mechanical pedestal would need annual service.

Power budget in practice

Published draw is 110–150 W typical with peaks to 180 W during snow-melt heating or cold start. On a 12 V system that is 9–15 A continuous — enough to matter on a sailboat at anchor with no generator running. Two rules that every installer we spoke to applies: size the circuit for the 180 W peak rather than the average, and feed the terminal from a dedicated breaker with cable gauge calculated for the actual run length. Voltage drop on a 20 m mast or arch run is the single most common cause of the random reboots owners later blame on the satellites. A DC-DC converter is cleaner than an inverter; inverters add conversion losses, idle draw, and one more failure point in a wet locker.

Mounting and sightlines

The array needs an unobstructed view of sky across its full 140° field of view. Radar arches, mast tops and hard-top biminis are the usual locations. Keep at least two metres of separation from radar scanners and VHF/AIS antennas to avoid desense, and never mount the terminal where boom gear, a halyard or a davit can sweep it. Deck penetrations must be properly sealed and bonded; a sloppy cable gland on a foredeck is how salt water finds the router three months later.

Installation walkthrough: a 48-foot cruising catamaran

A typical two-day yard job, in the order installers run it:

• Day one, morning — sightline survey. Stand where the array will sit and photograph the sky in four quadrants. On a catamaran the aft radar arch usually wins; the mast head is cleaner electrically but adds 15 m of cable and much harder service access. Mark the radar scanner and AIS whip positions and measure separation.
• Day one, afternoon — fabrication and mounting. A 316 stainless pad welded or clamped to the arch tube, isolation washers to prevent galvanic contact with aluminium fittings, and the terminal bolted down to spec torque. Bed the fasteners; do not rely on the gasket alone.
• Day one, late — cable route. Down the inside of the arch tube, through a compression gland into the starboard hull deckhead, then forward to the nav station. Leave a service loop at both ends. Label both ends.
• Day two, morning — power. A dedicated breaker on the house panel, DC supply rather than an inverter, cable sized for the measured run, and a voltage check at the terminal end while it is drawing peak. More than 3% drop means going up a cable size.
• Day two, afternoon — network and commissioning. Marine router, two ceiling access points (saloon and aft cabins), then a twelve-hour obstruction scan left running overnight. Final check: run the radar at full power and watch throughput for desense.

On commercial tonnage the same sequence expands rather than changes — two terminals on opposite sides of the superstructure for shadow redundancy, a bonded router, and the whole installation documented for the surveyor before it is energised.

Self-install versus certified installer

Owner installation is physically straightforward, and plenty of cruisers do it well. For commercial tonnage it is a different question: several flag states and most hull-and-machinery insurers expect equipment work to be performed and certified by an approved marine electrical contractor, and unapproved work can put both warranty and cover in dispute. If the vessel carries a class notation, involve the installer before anyone drills.

Starlink Availability at Sea: Ocean Coverage and Latitude Limits

Starlink availability as of Q1 2026 extends across all oceans between approximately 72°N and 56°S, per the interactive coverage map in the Starlink account dashboard. Inside that band there are no meaningful dead zones in open water — mid-Pacific, South Atlantic and Indian Ocean crossings are all served. Outside it, service stops: the Arctic Ocean above 72°N and the Southern Ocean approaches to Antarctica remain gaps, narrowing as Gen2 satellites and inter-satellite laser links accumulate on orbit. The pace of that closure depends on launch cadence and the shell configurations detailed in Starlink Satellite Constellation: Orbital Mechanics, Launch Cadence, and Deorbiting.

Availability is not uniform in quality inside the covered band. Coastal and near-shore waters sit under cells engineered for land populations, so a vessel 30 nautical miles off the Dutch coast sees far more capacity than one 1,500 nautical miles into the South Pacific. Cruisers who log continuous pings on ocean passages report modest extra jitter during satellite handoffs — single- to low-double-digit milliseconds — because fewer satellites are in view and the geometry is less forgiving. That is crowd-sourced observation rather than published telemetry, and it is small enough that no application on board will notice it.

Two operational notes. First, the latitude cut-off is hard rather than tapered: a yacht rounding Cape Horn at 55°58′S is inside coverage, while a Southern Ocean race route dipping to 58°S is not, and there is no degraded-but-usable middle ground. High-latitude operators keep an Iridium Certus or other L-band terminal active for those legs. Second, availability on a specific transoceanic track is not guaranteed until verified. Run the coverage map against your intended waypoints during voyage planning, not after departure — and check the country availability list for every landfall, because territorial waters follow national licensing rather than ocean coverage.

Maritime Pricing and Data Allowances in 2026

Three subscription tiers cover the vast majority of vessels, all billed in USD with local-currency options in 40+ countries.

Starlink plan and hardware pricing verified against the Starlink business pricing page and account dashboard, 19 September 2026.

Once the priority pool is exhausted, service continues at deprioritised speeds rather than stopping — an important distinction from legacy airtime contracts that either cut you off or bill punitive overage. Priority data can be topped up mid-cycle from the dashboard, which is how most cruising boats handle a single heavy month rather than moving up a tier permanently.

Pricing history matters for anyone budgeting a multi-year refit. Hardware was $5,000 at launch before the cut to $2,500; Standard and Premium have held at $1,000 and $5,000 since 2023; Maritime Lite arrived as the entry tier in Q3 2024 and has not moved. In late August 2026 SpaceX added a consumer-facing Personal Maritime plan at $185 per month with unlimited data and no 30-day travel limit, but with ocean data billed at a markedly higher per-gigabyte rate than the priority pools above. On its published terms it is a coastal and near-shore product, not an offshore-passage plan.

What a real installation invoice looks like

The $2,500 sticker is the smallest line on most jobs. Below is an anonymised, reader-supplied invoice for the 48-foot catamaran install described above: a south-coast UK yard, Q1 2026, converted to USD at the rate on the invoice. It is one job, not a national average, but it shows where the money actually goes.

Two lessons come straight off that invoice. Labour and fabrication together ($2,480) cost more than the terminal, and the spread between a cheap and an expensive install is almost entirely yard rate and cable distance — quotes reviewed by the desk put installed cost, excluding airtime, between $4,000 and $12,000 on mid-size yachts, with commercial installs carrying redundant terminals and bonded routing running past $25,000. The second lesson is that airtime dominates year one and every year after it, so the tier decision deserves more analysis than the mount does.

On tax: VAT is applied per jurisdiction on local-currency billing — 20% in the UK, 19% in Germany — while US-flagged vessels operating in international waters are commonly billed without VAT, subject to your own tax advice and the billing address on file.

Performance at Sea: Speeds, Latency and Weather Resilience

Speed reports published through 2025 and 2026 by cruising forums, delivery crews and fleet operators cluster around 25–100 Mbps download as the normal offshore band, with coastal peaks reaching about 220 Mbps in high-density zones such as the North Sea and the Caribbean. These are crowd-sourced figures rather than a controlled study, and they vary with cell load, but the band has been stable enough across sources to plan against. Upload sits at 5–15 Mbps, which is the real constraint for vessels pushing video, remote diagnostics or survey data ashore.

Latency of 25–45 ms is the headline advantage and the reason Starlink reset expectations for maritime satellite internet. Geostationary services sit above 600 ms, which makes voice calls awkward and remote desktop sessions close to unusable; on Starlink, shoreside IT can log into a vessel’s monitoring system and work normally. For a deeper breakdown of how those numbers behave under load, see Starlink Real-World Performance: Speed Tests, Latency, and User Experience.

Capacity planning on passenger vessels follows a different unit. Ferry and cruise operators design around approximately 10 Mbps of usable throughput per concurrently active passenger under normal browsing and streaming conditions — an operator planning convention rather than a SpaceX specification — which is why multi-terminal installations, not single dishes, are standard on those hulls.

Weather and motion

Rain fade is real but moderate. The link runs in Ku-band, where ITU-R P.618 propagation modelling puts meaningful attenuation at rain rates above about 25 mm per hour. The system compensates with automatic power adjustment and satellite re-selection, which shortens outages rather than preventing degradation. Crews report throughput halving in a heavy squall and recovering within minutes as the cell passes.

Motion tolerance is where the community and the specification diverge, so be precise about it: SpaceX does not publish a roll and pitch limit for the Flat High Performance terminal. What is published is the 140° field of view, which implies usable geometry through substantial heel. The ±25° figure repeated across cruising forums is a user-derived estimate, not a manufacturer number, and should be treated as a rule of thumb rather than a design limit. What crews consistently describe at the edge of that envelope is brief clipping — seconds, not session loss. Coastal cruisers rarely notice; delivery crews in a North Atlantic winter do. Where sustained heavy weather is normal, a second terminal on the opposite side of the superstructure is the practical mitigation, and it is cheaper than the support call at 3 a.m.

Regulatory Compliance: Flag States, SOLAS and Crew Welfare

The single most important compliance fact: Starlink Maritime is not type-approved for GMDSS and does not satisfy SOLAS primary safety communications requirements. It is supplementary equipment. A commercial vessel keeps its approved GMDSS installation, its EPIRB and its distress alerting chain exactly as before, and adds Starlink for operational and welfare traffic. This is not a temporary gap awaiting paperwork — the certification pathway for a service of this architecture is a multi-year process that SpaceX has not completed for any flag, and anyone selling the terminal as a distress system is misrepresenting it. Where owners want an alternative to the incumbent, the certified route is Iridium’s GMDSS service, recognised by the IMO in 2020.

Flag state equipment approval is the second requirement, and the one owners underestimate. Radio installations aboard a registered vessel fall under the national authority of the flag — the FCC in the United States, the Maritime and Coastguard Agency in the UK, the Australian Maritime Safety Authority, Transport Canada, and their equivalents elsewhere. A growing number of administrations now reference Starlink Maritime in their approved-equipment guidance or survey notes, which has reduced friction considerably, but there is no single consolidated register and the picture changes quarterly. Check your own flag’s published guidance directly before the survey; where no explicit listing exists, expect to document the installation, the power supply and the antenna siting for your surveyor. European operators should also track national-level licensing movement, which has been uneven — see Starlink in the European Union: Regulatory Landscape and National Rollouts.

On crew welfare, IMO guidance and the associated labour standards push operators toward providing shipboard internet access, and a Starlink installation comfortably satisfies that expectation. It does not discharge any obligation relating to mandatory safety equipment. For international waters, ITU filing and spectrum coordination sit with SpaceX, but compliance responsibility for the vessel — correct licensing, station logs, surveyor documentation — stays with the operator.

Maritime vs Inmarsat, Iridium and KVH: Satellite Internet Compared

The table separates two kinds of number deliberately. Throughput figures are the maxima each operator publishes on its own service literature. Monthly costs are indicative ranges from airtime reseller quotations current to Q1 2026, because — unlike Starlink’s published tiers — legacy maritime airtime is quoted per vessel and moves with contract term, committed volume and terminal lease structure. Do not budget from the cost column; budget from a quotation.

Throughput figures from each operator’s published service literature; airtime ranges from reseller quotations current to Q1 2026 and indicative only. Starlink speeds are crowd-sourced field reports because SpaceX publishes plan data allowances rather than guaranteed rates.

On cost per megabit for comparable data volumes, Starlink undercuts the geostationary incumbents by roughly an order of magnitude, and in some Fleet Xpress configurations considerably more. The trade-offs are polar availability and regulatory maturity: Inmarsat and Iridium carry decades of GMDSS pedigree and certified safety service that SpaceX does not. OneWeb, distributed through the same maritime service providers that sell Fleet Xpress, is the LEO alternative that arrives with a managed-service wrapper and polar reach.

The pattern that has settled across the fleet in 2026 is not replacement but layering — Starlink for bulk data, crew welfare and remote ops; a retained Iridium Certus or FleetBroadband terminal as the low-bandwidth fallback and high-latitude option; safety equipment untouched. Operators who removed their legacy terminal to save airtime fees have generally regretted it on the first polar or high-latitude charter. The same hybrid logic applies to individuals who move between hulls and shore, a pattern explored in Starlink for Digital Nomads: Portable Internet Across Borders.

Ordering, Installation Timeline and Support

The purchase path is short but has a maritime-specific gate.

• 1. Order through the Starlink business portal — Maritime is not available from the consumer checkout.
• 2. Complete the maritime onboarding questionnaire — vessel name, flag, tonnage, intended operating area and account contact. Tonnage above 300 GT routes to Enterprise sales rather than self-service.
• 3. Hardware shipping: 2–4 weeks across most regions through 2026, based on checkout quotations observed by the desk. Fulfilment has been stable since February 2026, after the longer backorders of late 2024. Confirm the date shown at checkout, since it varies by destination port.
• 4. Schedule installation: 1–2 weeks, driven mostly by port location and certified installer availability. Book the yard slot before the terminal ships, not after.
• 5. Activate and verify — run the coverage tool against your planned track, check every intended landfall against the country availability list, and confirm power draw under load before the first passage.

Maritime subscribers get 24/7 prioritised phone and email support, which is a material difference from consumer Starlink’s ticket-only channel. Be careful with the response-time numbers that circulate: the frequently quoted 15-minute target does not appear in Starlink’s published Maritime terms, and what is actually contractual is priority routing ahead of consumer queues. If response time matters to your operation — and on managed tonnage it does — ask your account contact for the current support annex in writing before you sign.

Post-purchase, the account dashboard carries the maritime documentation set: installation manuals, a power calculator and the coverage verification tools. Download the power calculator before your electrician quotes the job; it is the fastest way to settle the 12 V versus 24 V argument and to size the breaker correctly the first time.

The three mistakes that cost the most

First, under-specifying the DC circuit and then chasing phantom dropouts for a whole season, blaming the constellation for a voltage-drop problem. Second, assuming a consumer plan will hold offshore because it worked fine at the dock — it will not, and the failure happens at the worst point of the passage. Third, listing the terminal as safety equipment in the vessel’s ISM or safety-management documentation: surveyors notice immediately, and it is the fastest way to turn a connectivity upgrade into a findings list.

Frequently Asked Questions

What is the difference between Starlink Maritime and Starlink Roam?

They are different entitlements on the same constellation. Roam is a land-mobility plan: it authorises in-motion use ashore and in coastal waters, and it is sold with consumer hardware that carries a lower ingress-protection rating. Maritime carries the ocean entitlement and is sold with the Flat High Performance terminal. The boundary is enforced at account level, not by the dish: when a Roam account crosses out of its authorised service area the session drops or is heavily deprioritised, and no amount of clear sky brings it back. One practical detail that saves money — if you already own a Flat High Performance terminal, you can switch the plan attached to it from the Starlink dashboard at the next billing cycle rather than buying a second set of hardware for an offshore season.

Can I pause or cancel a Starlink Maritime subscription between seasons?

For the self-service Maritime tiers, billing is monthly with no minimum term, and the account can be paused from the dashboard and reactivated before the next passage — the pattern most Mediterranean and Caribbean seasonal owners use to avoid paying $1,000 a month for a boat on the hard. Two cautions. Enterprise agreements negotiated for tonnage above 300 GT are frequently term-committed with volume pricing, so the pause flexibility described above may not survive into your contract; read the schedule. And the hardware carries a limited warranty (12 months in most markets at time of writing, with a short return window from delivery) — confirm both figures at checkout, because they vary by shipping destination and have changed more than once.

How much data do I need for a month at sea?

Size it by application rather than by guesswork. GRIB weather files are trivial at roughly 50–200 KB per download, chart and almanac updates run a few hundred megabytes, and messaging is negligible. The consumption is entirely video: streamed HD burns about 3 GB per hour, a 4K stream three to four times that, and a video call roughly 1.5 GB per hour per participant. A two-person cruising yacht that streams in the evening lands between 150 GB and 400 GB a month. A 12-crew commercial vessel offering crew welfare Wi-Fi commonly runs 600 GB to 1 TB. The silent killer on both is unattended device updates — a dozen phones and laptops pulling OS updates over a satellite internet link can take 40 GB out of the pool before anyone has watched anything.

What do I do if the terminal fails mid-ocean?

You carry a fallback or you accept the outage. The Flat High Performance array is a sealed phased-array panel with no field-serviceable parts: there is no LNB to swap, no motor to rebuild and no radome to replace, so a hardware failure is an RMA at the next port rather than a repair at sea. Commercial operators handle this with a second terminal on the opposite side of the superstructure, which also solves shadowing from cranes and stacks. Cruising owners generally handle it by keeping an Iridium handheld or Certus terminal charged, since an L-band device that delivers a weather file and a phone call is a different category of insurance from one that delivers Netflix. Either way, test the fallback before departure, not when the primary link goes dark.

Do insurers and classification societies care who installs it?

On a classed or commercially registered vessel, yes. Classification societies — DNV, Lloyd’s Register, ABS, Bureau Veritas — expect fixed electrical equipment to be installed to the approved arrangement, with the supply circuit, cable routing and antenna siting documented for survey. Hull-and-machinery cover written on Institute clauses is generally conditioned on the vessel being maintained in class, so unapproved structural or electrical work creates an argument you do not want to have after a fire in a wet locker. Private pleasure craft face a softer regime, but the same logic applies to the warranty: drilling an arch tube badly and flooding a hull deckhead is not a satellite problem. If the vessel carries a class notation, bring the installer into the conversation before anyone drills.

How do I stop crew and guests burning through the priority data pool?

At the router, not at the dish. Starlink hands you a flat connection and no per-user controls, so quota management lives in the marine router you put behind it. The configurations that work in practice: a separate guest or crew VLAN with its own bandwidth ceiling, per-device or per-cabin daily caps enforced by a captive portal, and a scheduled block on OS and app update traffic during the priority-data window. Fleet operators typically push this further with per-crew-member login accounts and monthly allowances. When a month runs long anyway, priority data can be topped up mid-cycle from the dashboard, which is almost always cheaper than moving permanently to the next tier.

Does Starlink Maritime work inside the territorial waters of countries where Starlink is not licensed?

Not reliably. Coverage on the open ocean is delivered under the flag-state and ITU framework SpaceX operates within, but the 12-nautical-mile territorial sea of a coastal state is that state’s regulatory jurisdiction, and where a national regulator has not granted market access the service can be restricted or unavailable. This bites on cruising routes through West Africa, parts of South and Southeast Asia and several sanctioned jurisdictions, and the picture changes as licences are granted. The practical routine is to check your intended landfalls against the country availability list in your Starlink account before you plan an arrival around a video call or a crew change, and to keep a legacy terminal live on itineraries that touch unlicensed waters.

Can Starlink Maritime replace my ship’s existing satellite system?

Not as a primary safety system. Starlink Maritime is not type-approved for GMDSS and does not satisfy SOLAS distress and safety communications requirements, so on a commercial vessel it remains supplementary to approved equipment. Where owners genuinely want to move away from a legacy incumbent, the certified alternative is Iridium’s GMDSS service, recognised by the IMO in 2020, rather than Starlink. Vessels operating under the Polar Code face a further constraint, since safety communications must be demonstrably available for the intended area of operation — precisely where Starlink’s latitude limits bite. The settled 2026 pattern is layering: GMDSS untouched, a retained L-band terminal as fallback, and crew welfare, routine operational traffic and remote monitoring moved onto Starlink.
