Solo safety
Garmin inReach Mini 3 Plus (348 € HT) er staðallinn fyrir einmenna siglingar í Frakklandi: 24/7 Iridium neyðarsími, gagnvirk SMS fyrir fjölskyldu og skipuleggjendateymi, 100 g í vantsjónum. Engin talan — þetta er meðvitað val, því maður kaupir ekki síma, maður kaupir líftrygging sem vegur 100 g.
Total budget (terminal + 1-year Garmin Standard subscription): ~ $530 USD ex-works

Gerfi Garmin inReach Messenger Plus (279 € HT) bætir við stuttu hljóðminnispunktum miðað við Mini 3. Ekki er um raunverulega gervihnattahljóðrás að ræða, en nægir til að segja "við erum komin til Cala Galera, allt er kyrrt". 28 daga sjálfvirkt rekstur í sporing án endurhlaðningar — gagnlegt á 30 feta bátum án stórra rafgeymis.
Total annual budget (terminal + subscription): ~ 460 € HT

Símilinn Iridium 9575 Extreme (1 573 € HT) hefur verið okkar viðmiðunarbúnaður fyrir háfjörð í 15 ár. Upplifun með beinum hljóðsambandi án þess að vera háður snjallsímum (þannig áreiðanlegur ef flugtæki um borð bilast), innbyggð fleygantennan (ekki þarf að borða í gegnum skrokkinn), IP65 + MIL-STD-810F (þolir sjávarbylgjur og fall). Til viðbótar, bæta við Iridium GO fyrir tölvupóst og samþjöppuð veðurskilyrði ef áhöfnin notar snjallsíma.
Combined budget 9575 + GO + 1-year subscriptions: ~ 3,800 € HT

Iridium GO Exec (2 106 € HT) á Certus 100 er okkar "skynsamlega" hámarkssat: 88 kbps niðurstreymi gerir það mögulegt að senda tölvupóst með viðhengjum, niðurhala háupplausnar-GRIB og hringja með HD gegnum app. Umfram það — streymi, myndasamtöl — verður að skipta yfir í Starlink Mini Marine (~ 650 € HT endir + 50-80 €/mánuð Roam Global). Skysat selur ekki Starlink-endana beint, en við veitum uppsetningarútilykni (vatnsþétt Scanstrut brú, hágæðakablar).

View GO ExecThe 3 mistakes that come up when a customer chooses their satcom equipment without consulting us.
The standard GO tops out at 2.4 kbps. That’s 1980. You can send a 200-word text email in 2 minutes. You can’t load a web page, make a WhatsApp video call, or download an uncompressed weather chart. For real data: GO Exec (Certus 100) or Starlink Mini.
The Garmin inReach Mini 3 Plus and Messenger Plus are SMS communicators; they are not phones. They send text messages (160 characters). The Messenger Plus can record short voice notes — but not live calls. To hear a loved one’s voice offshore, you need an Iridium 9575 or GO.
The Starlink antenna is easy to mount — but the PoE cable running down from the deck requires a correctly sized watertight deck gland (Ø30 mm = Scanstrut DS30-SL-BLK). Without it, a leak is guaranteed at the first slamming wave. And plugging the 12 V power supply directly without an isolated converter will fry the power rectifier within 6 months of saltwater sailing.
4 questions to identify the satellite terminal suited to your program and annual budget (terminal + subscription).
Skysat no longer distributes the 9555 (obsolete model replaced by the 9575 Extreme — improved IP65 rating + MIL-STD-810F + integrated GPS). The Inmarsat IsatPhone 2 is not sold by Skysat — its geostationary satellite coverage depends on a visible horizon (problematic at high latitudes and near landmasses). The Iridium LEO ecosystem covers 100 % of the globe without conditions. For our offshore sailing clientele, this is more relevant.
Yes, provided you have a Roam Global subscription (€50 or €80/month; check the exact coverage area before departure — central Pacific remains partial in 2026). Continuous sea coverage in the Mediterranean and North Atlantic. Since the Starlink constellation is in LEO (~550 km), the throughput is equivalent to terrestrial use. Real limitation: 12 V power consumption (25–50 W), so proper wiring and surge protection are mandatory.
The Mini 3 Plus (€348 ex VAT) is more compact (100 g vs 113 g), more physically durable, and has a sun-readable color screen. The Messenger Plus (€279 ex VAT) is cheaper, adds short voice notes (2025 new feature), and lasts 28 days on 10-minute tracking vs 14 days for the Mini 3. Solo racing / grab bag: Mini 3. Crewed cruising with family voice notes needed: Messenger Plus.
The standard GO (€1,143 ex VAT) caps at 2.4 kbps — the speed of a 1990s analog modem. Sufficient for: short text emails, compressed weather GRIB files (XGate, PredictWind), SMS, voice via app. Not sufficient for: large attachments, normal web browsing, video calls. The Exec GO (€2,106 ex VAT) runs on Certus 100 (88 kbps DL) = real email with attachments, light web browsing, HD voice. The Certus plan is ~2× more expensive (~€150/month) but offers incomparably more comfort. Our workshop recommendation: if you stay at sea 6+ months = Exec GO, otherwise standard GO.
For seasonal use (transatlantic race + 3 months cruising then boat ashore): prepay. Load 200 or 500 minutes, which roll over. No inactive monthly subscription. For continuous use (round-the-world, professional charter): postpay with included monthly package, more cost-effective beyond ~50 minutes/month. Skysat distributes both models — we calculate your break-even point when purchasing the terminal.
Skysat does not distribute the Starlink terminal (not part of our product range at this time — we focus on mature LEO + GEO satcom solutions with professional SLA such as Iridium). However, we supply and install the deck integration kit: waterproof pass-through Scanstrut DS30 or DS16 depending on cable diameter, high-quality extension cables (8 m or 30 m), 12 V → AC or marine PoE converter for clean power supply. See Starlink installation collection.
Skysat has distributed Iridium and Garmin (inReach) since 2018. Comparator based on 200+ marine satellite installations from 2020–2026, including solo racing, offshore cruising, transatlantic races, and round-the-world voyages. 2026 indicative distributor prices in France — operator subscriptions not included, rates vary by operator (Iridium Direct, MSat Communications, Skytrac, etc.). Starlink Mini Marine listed as a technical reference — Skysat does not distribute the terminal but offers the Scanstrut installation kit.
