Starlink on a sailing yacht: what actually works in 2026

Three years ago, "internet on a sailing yacht" meant rationing data, praying for a marina signal, and cancelling the afternoon call when the anchorage was one bay too far from the cell tower. Starlink Maritime changed the ceiling — it did not change the floor. This guide covers what actually works in 2026, from someone running eight boats a year on it.

What Starlink delivers in practice

On a static anchor in the Mediterranean, Starlink Maritime gets us 100–250 Mbps down, 10–30 Mbps up, and 30–60 ms round-trip latency. Those numbers are stable enough for 1080p Zoom, Google Meet, Loom recording, SSH sessions, and git pushes. They are not stable enough to treat like a home fibre line: the dish occasionally drops for 1–5 seconds when it re-aligns with a new satellite, and any video call will stutter through that.

Latency is the real story. The old geostationary satellite internet (V-Sat, Inmarsat) had 600 ms+ round-trip times — unusable for anything interactive. Starlink's low earth orbit puts you under 60 ms from the open sea, which is why the "is this a video call I can actually take" question now has a yes for the first time on a 40-foot catamaran.

Where coverage actually drops

Three situations cost you internet even with Starlink on board:

• Anchorages shadowed by steep cliffs. The dish needs a clear view of about 100° of sky. Some Croatian bays under 300-metre cliffs fall below that threshold from certain positions on the boat.
• Long passages in a sub-optimal Starlink service zone. The "mobile" plan covers most of our routes, but a handful of open-water stretches in the Aegean and Andaman have intermittent drops.
• Under sail with the mainsail casting a shadow on the dish. Easy to fix if you think about it when rigging, easy to forget.

Why we still carry 4G

Every captain on our routes carries a Turkish, Greek, or Croatian SIM with a 50–100 GB monthly plan, split on a MiFi or phone hotspot. Near shore — which is most of our anchorages — 4G or 5G is faster than Starlink's "busy" moments and has zero satellite-realignment stutters. On every cruise, guests end up using both: Starlink for bandwidth, 4G for latency-critical moments.

Practically: if you are about to join a high-stakes call, plug into the 4G hotspot 30 seconds beforehand. Pairs beautifully with a USB-C Ethernet adapter if you care about stability.

Bandwidth etiquette on a shared boat

Eight people on one Starlink is more than enough for normal work — but not if three of them are running simultaneous Loom recordings in 4K. We do not police it; we just ask guests to check with the rest of the boat before starting anything heavy. In three years, that social norm has been enough.

What to test before you commit

If you have never worked over Starlink, try the ground-based Starlink Mini for a day first (every major city has one you can borrow or rent). The connection on the boat is very similar — if your workflow tolerates one there, it will tolerate this.
