The Universal Shipborne Automatic Identification System (AIS) is a system of transponders installed on vessels which transmit over two dedicated digital marine VHF channels. An AIS transponder sends AIS signals, making your vessel visible to others with AIS equipment. It also receives AIS signals from AIS equipped vessels, Aids to Navigation and portable man overboard devices.


Unlike an ordinary AIS which only sends and receives data, smartAIS from Vesper Marine is an active safety system with smart alarm logic that proactively alerts you when you have potential collision situations, it plots your anchor position and alerts you if your anchor drags, it continuously watches for a man overboard and triggers an alarm for quick action.

This is a fantastic piece of kit. The menus are simple and easy to use, even while in a heavy seaway, it’s incredibly smart about conserving power, and best of all it has the smartest alarms I’ve ever seen on an AIS device.

The WatchMate Vision is a truly magnificent instrument with intelligent in-built software. One may compare its features to some sort of ‘ABS for a car’. Nothing less! It proved to be a true ‘anti-collision’ device. I consider myself a happy owner and for the record, I have never given such feedback to anyone yet.
