Full throttle, still connected.

SHORT ANSWER

A jet ski covers more water in ten minutes than a swimmer in an hour — the beach where they last saw you becomes irrelevant fast. VesselSOS keeps your live position, course and battery in a browser ashore, and puts the right rescue centre one tap away.

Navigation apps stop where trouble starts

Most jet-ski apps focus on charts, no-wake zones and tides, not on calling for help. When someone is in the water, you need the rescue centre responsible for where you actually are — anywhere on Europe’s seas. VesselSOS picks it from your position, not your SIM card, and pre-fills the MAYDAY wording and the SMS to your people.

The link rides with you

Start tracking at the ramp, put the phone away and ride. The person ashore watches your position and course live and sees your battery level — a quiet phone never has to mean the worst. Nothing to install and no account on their side.

A breakdown is not a MAYDAY

An empty tank two miles out is a technical-assistance case, not a rescue case. In Estonia, Finland, Sweden and Germany the app points you to the local assistance service and dials the member number from your profile — and when it genuinely is life-threatening, one tap on SOS, one yes/no question, and the app dials the rescue centre. Unsure of the line? Read Mayday or a tow?

HONESTY CLAUSE

VesselSOS is not an anti-theft tracker and it does not promise rescue. It is a quick way to be seen from shore and to call the right number.

Frequently asked

Does tracking work at speed, with spray?+

Yes — the phone stays zipped in your vest or a mount; tracking runs by itself and needs no attention while you ride.

I ride abroad on holiday. Does it still know who to call?+

Anywhere on Europe’s seas, yes — the responsible rescue centre is chosen by your position, from the Baltic to the Mediterranean and the Black Sea. Further afield, call 112 or the local emergency number; the app does not know those centres yet. On a rented ski, set the craft type to jet ski in your profile.

What does the person ashore need?+

Nothing. The link opens in any browser, no app, no account.
