On a smaller boat, a Man Overboard can happen fast, and go unnoticed even faster.
No crew watching every angle. A wave, a wash from a passing boat, a dog leaning too far over the side. By the time you realise someone's missing, the boat hasn't stopped. Sails still up, engine still running. Turn back and you could be a few hundred metres from where they actually went in.
That's the gap OLAS Tag closes. A low-cost wireless MOB alarm that pairs straight to your phone. No chartplotter, no extra hardware, just the Tag and the OLAS app. Built for smaller power or sail boats, family days out, and anyone bringing the dog along.
Alert fires instantly on your phone the second someone goes over
GPS locked and stored at the exact point of loss, before you've even turned the boat
Track Back guides you home — not to where you are now, to exactly where they went in, so you can run a proper search pattern if they're not in sight yet
SMS sent automatically to an emergency contact with the position included, no typing needed
Map view with lat/long ready to pass straight to the Coast Guard over VHF
The video below shows it for real: boat moving away from the point of loss, turning back, and the Tag reconnecting as it comes back into range.
