Solo safety
Garmin inReach Mini 3 Plus (348 € brez DDV) je standard za samostojne tekmovalce v Franciji: SOS prek Iridium 24/7, dvosmerna SMS za življenjsko nit družine + ekipa za rutiranje, 100 g v žepu pod suknjo. Brez glasovnega klica — to je namerno, ne kupujete telefon, kupujete življenjsko zavarovanje, ki tehta 100 g.
Total budget (terminal + 1-year Garmin Standard subscription): ~ 530 € HT

Garmin inReach Messenger Plus (279 € brez DDV) omogoča kratke glasovne sporočila v primerjavi z Mini 3. Ni pravo satelitsko klicanje, vendar zadostuje za sporočilo 'prispeli smo v zaliv Cala Galera, morje je mirno'. Avtonomija 28 dni pri sledilnem načinu brez polnjenja — uporabno na čolnih do 30 čevljev brez velike baterijske kapacitete.
Total annual budget (terminal + subscription): ~ 460 € HT

Iridium 9575 Extreme (1.573 € brez DDV) ostaja naš standard v ladjedelnicah za daljinsko plovbo že 15 let. Izvirni glas brez odvisnosti od pametnih telefonov (zato zanesljiv v primeru okvare letalske elektronike na krovu), vgrajen razširljivi antena (ni potrebna vgradnja z vrtanjem), IP65 + MIL-STD-810F (odporen proti udarcu valov in padcu). Za dodatno uporabo lahko dodate Iridium GO za e-pošto in stisnjeno vremensko napoved, če posadka uporablja pametne telefone.
Combined budget 9575 + GO + 1-year subscriptions: ~ 3 800 € HT

Iridium GO Exec (2.106 € brez DDV) na Certus 100 je naš razumni vrhunec satelitskih terminalov: 88 kbps prenosa omogoča pošiljanje e-pošte z prilogami, prenos visoko ločljivih GRIB datotek in HD klice preko aplikacije. Če želite več — npr. video streaming ali videokonference — morate preiti na Starlink Mini Marine (~ 650 € brez DDV terminal + 50-80 €/mesec Roam Global). Skysat ne distribuira terminala Starlink neposredno, vendar nudimo namestitveni komplet (vodotesna prehodna skrinjica Scanstrut, kablovje visoke kakovosti).

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 cannot 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 — not a live call. To hear a loved one’s voice from offshore, you need an Iridium 9575 or GO.
The Starlink antenna is easy to mount — but the PoE cable running 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 boarding wave. And powering the 12 V unit without an isolated converter will fry the power rectifier within 6 months of saltwater sailing.
4 questions to identify the sat terminal suited to your program and your annual budget (terminal + subscription).
Skysat no longer distributes the 9555 (discontinued 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). In the Mediterranean and North Atlantic, continuous sea coverage is available. Since the Starlink constellation operates in low Earth orbit (~550 km), the throughput is equivalent to terrestrial use. The real limitation is the 12 V power draw (25–50 W), so proper wiring and surge protection are mandatory.
The Mini 3 Plus (348 € HT) is more compact (100 g vs 113 g), more physically durable, and has a color screen readable in full sunlight. The Messenger Plus (279 € HT) is cheaper, adds short voice notes (2025 new feature), and lasts 28 days in 10-minute tracking vs 14 days for the Mini 3. Solo racing / grab bag: Mini 3. Crewed cruise with family voice note needs: Messenger Plus.
The standard GO (€1,143 ex-VAT) tops out 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. Insufficient 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, HD voice. Certus plan costs ~2× more (~€150/month) but offers incomparably better comfort. Workshop recommendation: if you stay 6+ months at sea = Exec GO, otherwise standard GO.
For seasonal use (transatlantic + 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 plan, more economical 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 current product range — we focus on mature LEO + GEO satcom solutions with professional SLA such as Iridium). However, we supply and install the deck integration kit: waterproof bulkhead 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 sat installations from 2020–2026, in solo racing, offshore cruising, transatlantic races, and round-the-world voyages. 2026 indicative distributor prices in France — operator subscriptions extra, 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.
