CPAS is a live safety and visibility layer for clubs and organisations on UK coastal waters — built for the gap SafeTrx left behind, and already running on the water today.
Every day, thousands of kayakers, paddleboarders, paramotor pilots, and small vessel operators enter UK coastal waters carrying nothing but a smartphone. To the RNLI crews sworn to protect them, they're invisible — no AIS signal, no float plan, no electronic trace. When something goes wrong, the search starts from the last place someone saw them, not from verified position data.
On 31 December 2025, RYA SafeTrx — the UK's only government-endorsed coastal tracking platform — closed permanently. Over 13,000 registered users lost their safety net overnight, and thousands still have no viable replacement.
This isn't just about a single dark target on a paddleboard. It's the same gap for a full crew heading out for a day's racing, or a sailor plotting an offshore passage — the traditional tools for that (a paper float plan, a phone number for "call this person if I'm late back") haven't changed in decades, and none of them are live.
Good crews already do this the old way: someone files a plan before they go, someone else is the person you call if things go wrong, and everyone keeps half an eye on the weather and the clock. CPAS doesn't replace that instinct — it takes every part of it and makes it live, automatic, and visible to the people who'd actually need it in an emergency.
Plot your route before you go — solo passage, a race, or a club day out — so there's a real plan on record, not just a guess at your last-known position.
Every skipper carries the device; crew are manifested by name, phone, and emergency contact, device or no device. Token Holders — a partner, a family member, a friend, or your club commodore, whoever you'd actually want told — can follow your position live for the whole voyage, and are notified automatically if something's wrong. It's a real-time safety net, not a phone call that assumes someone remembers to make it.
CPAS combines live AIS commercial traffic with mobile GPS position data, rendered in a navigable 3D Digital Twin that shows every vessel, kayaker, and pilot in the same shared display, in real time.
Where traditional tracking shows a flat map, CPAS shows a living volume — a kayaker at sea level, a paramotor pilot at 300ft, a ferry entering the harbour mouth, all visible, all in one place.
It's the float plan you always meant to leave with someone, the crew list that's actually accessible in an emergency, and the real-time position that means a search starts from a known point — not a guess. All in one system, running the whole time you're out.
If you run a club, you already know the gap: a Float Plan on paper or in a WhatsApp group, a Commodore who's the unofficial safety net for everyone out on the water, and no real way to see who's actually still out there. CPAS replaces that with something live — and it costs your club nothing to join.
Register Your ClubCPAS was built for clubs first, but the same live position data is useful further afield.
Anonymous CPAS position data delivered via API into existing Vessel Traffic Service displays, giving port controllers a complete picture of commercial AIS traffic and recreational users together, in real time. No new hardware on commercial vessels.
Verified users with genuine trajectory and identity data give insurers something to actually price small-vessel risk against, instead of estimating it blind.
The same verified-position baseline that protects a club member is a force multiplier for coastal security more broadly — a known, verified presence is easy to tell apart from one that isn't.
CPAS isn't a concept waiting for validation — it's running on the water now.
We're not at public launch yet. But the digital twin is built, the corridor is active, and the club conversations are already happening.
For commodores and club administrators: bring your members onto CPAS, free, in about five minutes.
