The best Starlink for boats in 2026.

Why Starlink changed marine internet

Three years ago, the best marine internet you could buy was a Pepwave cellular router pulling 4G from shore towers — great within 15 miles of land, nothing beyond that — paired with an Iridium GO! for offshore text messages and weather files at 2.4 kbps. If you wanted real internet offshore, you needed a $50,000 VSAT terminal and a $3,000/month plan.

Starlink destroyed that entire stack. For $249 of hardware and $50 a month, any recreational boat can now have broadband internet sitting at anchor in the Bahamas or moored off the coast of Maine. That's not a small improvement. It's a category-defining change.

The complication is that Starlink's product lineup has grown into a maze: four different dishes (Mini, Standard, High Performance, Flat High Performance), five service tiers (Residential, Regional Roam, Global Roam, Mobile Priority, Business), and a rulebook that treats "at anchor" differently from "in motion" differently from "in motion beyond 12nm of shore." Pick the wrong combination and you'll either overpay by thousands or violate Starlink's terms of service without realizing.

This guide is the decoder ring.

The three questions you must answer first

Before you look at a single product, answer these three questions honestly. Your setup is a direct consequence of the answers.

Question 1: Will you use internet while moving at more than 10 mph?

Starlink's in-motion rules draw the line at 10 mph (16 km/h). Below that speed, or sitting still at anchor, any Starlink dish works on any Roam plan. Above that speed, you need Mobile Priority service ($250+/month) AND the Flat High Performance dish ($2,500). No exceptions, no workarounds that don't violate the TOS.

For most sailboats, this rule is invisible — hull speed is typically 6-8 knots, well under the threshold. For power cruisers doing 8-10 knots displacement, still under. For sportfishers and go-fasts cruising at 20-40 knots, the threshold matters enormously.

Question 2: Do you need internet beyond 12 nautical miles from shore?

Roam plans cover "inland waterways and territorial waters" — which means within 12 nm of any coastline. Once you cross that line, standard Roam plans stop working unless you've activated Ocean Mode (Roam Unlimited only) or you have a Priority plan.

For coastal cruising — ICW, Great Lakes, Chesapeake, Puget Sound, Florida Keys, most of the Caribbean from island to island — you never leave that 12nm band. For Atlantic crossings, Pacific passages, or even some Gulf of Mexico routes, you will.

Question 3: How many days per year will you actually use it?

A $165/month unlimited plan pencils out to $2,000/year. If you're a weekend boater using 20 days per year, you're paying $100 per day for internet. The monthly plan is easy to cancel and re-activate; doing so seasonally often saves more than the entire cost of a cheaper plan.

Starlink plans have no contract and no commitment. You can suspend a plan and reactivate it when you need it. Budget-minded boaters should be thinking in terms of "active months per year," not "monthly cost."

The plans, decoded

Starlink's consumer plans for mobile/marine use break down to five tiers as of April 2026. Residential plans exist but don't apply to boats — they require a fixed service address.

The Ocean Mode footnote

Ocean Mode is the cheapest legal way to use Starlink beyond 12nm, available only on Roam Unlimited plans. It adds ocean coverage at $2 per GB consumed beyond the coast. For a typical cruiser making a 3-day passage and using 20 GB of data (light streaming, weather downloads, video calls to family), that's $40 — far cheaper than upgrading to Mobile Priority.

You toggle Ocean Mode on from the Starlink app when you need it and off when you're back in coastal waters. It's the feature most offshore-but-budget-conscious sailors don't know about.

The dishes, compared

Four hardware options matter for boats. Ignore the Starlink Business offerings — those are aircraft and fleet-grade equipment that don't make sense for recreational use.

The in-motion rule that trips up most buyers

The most misunderstood element of Starlink for boats: the 10 mph threshold. Until you've internalized it, you will either overbuy or violate TOS. Here's the clean version.

Below 10 mph / at anchor / at dock: any Starlink dish, any Roam plan, works fine. This covers 95% of the time for most sailboats and cruising powerboats. Anchored overnight? Totally fine. Motoring at 7 knots through the ICW? Fine. Drifting while fishing? Fine.

Above 10 mph: you need the Flat High Performance dish AND a Mobile Priority plan. No substitutes. Running offshore at 20 knots on a sportfisher? You need the $2,500 dish and $250+/mo plan. Cruising at 25 knots on a center console? Same.

The Mini and Standard dishes are not prohibited from working above 10 mph — they'll physically continue to operate. But Starlink reserves the right to throttle, disconnect, or terminate service for TOS violations. In practice, hobbyist boaters report intermittent disconnects above the threshold rather than account termination, but we've seen reports of both. Don't plan your charter business around ignoring the rule.

For the vast majority of recreational boaters — weekenders, coastal cruisers, ICW traffic, lake users, sailboats under 45 feet — the 10 mph threshold is never a problem. If your boat tops out at 8-9 knots of hull speed, you literally cannot violate it by accident. If you regularly cruise at 20+ knots, plan for the Flat HP + Priority combination or understand you're running gray-market.

Our picks in detail

Four picks for four distinct boater profiles. Pick the one that matches how you actually use your boat, not how you imagine you might.

Top pick: Starlink Mini + Regional Roam 100GB ($249 + $50/mo)

This is the right answer for 80% of people reading this guide. You have a boat. You go out on weekends and the occasional longer trip. You want Netflix at anchor, video calls from the marina, and weather downloads before you head out. You don't go offshore. Your boat doesn't exceed 10 mph often, if ever.

The Mini is small enough to stow when you're not aboard, draws little enough power to run off house batteries, and costs half what a Standard dish does for 95% of the same experience. 100 GB per month is roughly 30 hours of HD Netflix or 100+ hours of video calls — plenty for most boaters.

Upgrade: Starlink Mini + Roam Unlimited ($249 + $165/mo)

Same hardware, bigger plan. This is for liveaboards, remote workers, digital nomads, or anyone who uses the boat as their primary home part of the year. The $115/month difference buys you unlimited data and the Ocean Mode option for offshore passages (pay-as-you-go at $2/GB).

If you're running a video-call-heavy job from the boat, streaming 4K, or uploading large files (photographers, videographers, content creators working from a boat), the unlimited plan pays for itself versus the data cap on Regional Roam.

Offshore: Flat High Performance + Mobile Priority 50GB ($2,500 + $250/mo)

The serious boater's Starlink. This is for sportfisher captains running offshore charters at 25+ knots, bluewater cruisers making Atlantic/Pacific passages, expedition yachts, and anyone who genuinely needs internet while the boat is moving at speed.

At $3,000 for the first month and $3,000/year thereafter for the minimum plan, this isn't a casual purchase. But it's still 10-20× cheaper than the equivalent VSAT setup would have cost five years ago. For charter operations where the boat's earning potential depends on guest connectivity, it pays for itself in a single booked week.

Budget: Used v2 Standard dish + Regional Roam 100GB (~$150 + $50/mo)

The eBay play. If you're technically comfortable and risk-tolerant, a used v2 Standard dish from an RV owner who upgraded costs $100-$200 and delivers the same service experience as a new $349 kit. Total startup cost under $300 is compelling.

Buy only from sellers who explicitly confirm the dish is unlocked (not tied to a Residential account). Ask for photos of the kit number and confirmation the previous account has been cancelled. Budget another $30-50 for a replacement power supply if the seller doesn't include one — RV kits often don't include the DC-power converters useful on boats.

The power draw reality

Starlink isn't free electricity. Here are the honest numbers from real boat installations:

• Starlink Mini — 20W idle, 40-50W active (streaming, downloads), 75W peak (bootup, reconnects). For a 24-hour day with 4 hours of heavy use, budget about 700 Wh/day.
• Starlink Standard — 35W idle, 75-100W active, 130W peak. Same 24-hour budget is closer to 1,400 Wh/day — double the Mini.
• Starlink Flat HP — 50W idle, 100-150W active. Runs hotter than the others and has more aggressive thermal management, so expect occasional brief power spikes.

For a sailboat with a 400 Ah battery bank at 12V (4.8 kWh usable at 50% depth of discharge), the Mini consumes about 15% of daily capacity. The Standard consumes 30%. The Flat HP consumes 40-50%. This is why Mini is our top pick for sailboats specifically — power is a finite resource, and Starlink can easily become the largest single draw on the boat.

A solar install that offsets Starlink consumption is roughly 200-300W for the Mini and 400-500W for the Standard in temperate climates. Pair with a lithium bank and you've eliminated the power question entirely. See our solar power for smart boats guide for panel sizing, controller picks, and a full kit shopping list.

Installation and mounting

Installation varies from "set it on the cockpit seat" to "permanent radome mount at the masthead." For recreational boaters, simpler is better.

Temporary / portable install

For the Mini specifically: put it on the cabin top, run a 20-foot power cable through a hatch or existing cable gland, connect power. Deploy when needed, stow when done. Takes 60 seconds and survives salt air fine because it's indoors when not in use.

Semi-permanent install

RAM mounts, Scotty mounts, and a few boat-specific Starlink brackets let you mount a Mini on a rail, arch, or existing antenna pole. This keeps it deployed while aboard but removable when you leave. Amazon sells dozens of these; most are $30-$80.

Permanent install

For the Standard and Flat HP dishes, permanent mounting on a mast, arch, or T-top is usually how they're installed. Beam-bolt mounts for the Flat HP cost $200-400; arch mounts for the Standard run $150-$300. Budget an afternoon and someone with marine-grade electrical skills if you're running high-gauge DC power through the boat.

Why you probably also want Iridium

Starlink is broadband internet. Iridium is a different thing: a genuinely-global, low-bandwidth, mission-critical satellite network that works in conditions where Starlink doesn't. Offshore cruisers should consider having both, for different reasons.

Starlink requires line-of-sight to low-earth-orbit satellites overhead. Rain, heavy cloud cover, and vessel motion interrupt service. At anchor in calm weather, it's rock-solid. In a squall line or with the boat heeled over at 20 degrees, it drops.

Iridium uses geosynchronous satellites with global coverage including the poles. It works through weather, at any boat angle, and anywhere on the planet — but at satellite-phone speeds (2-88 kbps), not broadband. You use Iridium for short text messages, weather GRIB downloads, and voice calls when Starlink is unavailable.

The Iridium GO! exec is the modern iteration — a Wi-Fi hotspot that connects your phone/laptop to the Iridium network via its own app. Voice, text, email, WhatsApp, weather services, basic social media all work at satellite-phone speeds. Think early-2000s-internet bandwidth, not streaming video, but truly anywhere.

For coastal-only boaters, skip Iridium. For anyone doing offshore passages, treat the GO! exec as a safety device more than a connectivity device — a backup to your primary Starlink and a complement to your EPIRB for SOS capability. Bluewater cruisers typically have both, often layered on top of a cellular boat monitoring setup that handles unattended alerts near shore. Charter operations doing ocean crossings often have both plus a VSAT for redundancy.

Frequently asked questions

Can I use a Residential Starlink account on my boat?

Technically no — Residential plans require a fixed service address and use that address for satellite routing. Some boaters have used Residential plans while docked at a marina using their home address, but service is often unreliable because the dish is hundreds of miles from the registered location. Starlink has also been known to flag and restrict these accounts. Use Roam or Priority plans for actual boat use.

Does Starlink work when crossing oceans?

Only with Ocean Mode (Roam Unlimited + $2/GB) or Mobile Priority service. Regional Roam stops at 12nm from shore. For an Atlantic crossing of ~3,000 nm, budget Ocean Mode consumption of about 15-30 GB ($30-60 in data costs) if you're conservative with use.

Can I pause service between seasons?

Yes, on any Roam plan. Log into the Starlink account, suspend the plan, pay nothing during the pause months, reactivate when you need it. This is the single most useful feature for budget-conscious seasonal boaters. Mobile Priority plans can also be paused but are often used year-round.

What about competitors — Amazon Kuiper, OneWeb?

Amazon's Project Kuiper is launching satellites through 2026 but consumer hardware isn't yet available in the US. OneWeb is primarily focused on enterprise and maritime commercial customers, not recreational boaters. For the next 12-24 months, Starlink remains the only realistic LEO broadband option for recreational boats. Revisit when Kuiper's consumer product ships.

Will it replace my cellular router?

Not entirely. Cellular is still faster and cheaper within 10 miles of shore in most US coastal areas. Many cruisers run both — a Pepwave router for close-to-shore cellular plus Starlink for farther-out broadband. A router that supports "SIM + Starlink failover" (Pepwave MAX Transit Mini and similar) is the cleanest setup for boats that want the best of both. See our cellular router buyer's guide for the full comparison.
