Sea kayaking’s real risk is not distance — it is a capsize in cold water, with minutes to solve it. VesselSOS gives you a float plan someone actually watches: a live link ashore, and an emergency screen with your position, MAYDAY wording and the right rescue centre.
A crossing that is routine in July is a survival problem in April. If you go over and cannot re-enter, the clock is short — and the person who raises the alarm will be the one ashore. With a live link they see your dot stop in open water and know it is time, instead of discovering at dusk that you never came back.
The paper float plan fails the moment plans change. The live link is the float plan: your actual position, course and battery, in any browser, no app for the watcher. How it works in detail is on the tracking page.
From a swamped cockpit you will not operate a VHF you do not carry. The emergency screen opens on your coordinates in the format a rescue centre asks for, the MAYDAY text is pre-filled with your craft and position, and the SMS to your people goes out through coverage too weak for data. GPS itself needs no network at all.
Skills first: a PFD, a re-entry you have practised, and judgement about the forecast. VesselSOS is an aid, not a rescue service — in immediate danger, 112 first.
Your position, the MAYDAY text and craft details are on the phone fully offline. Calls and SMS need a network; SMS gets through where data has already died.
Yes — each kayaker shares their own link, and the shore contact sees the whole group side by side in browser tabs.
Tracking runs only while you switch it on, and the watcher sees your battery level — so you can turn it on for the crossings and off in the sheltered stretches.
