I find it concerning how many people consider AIS a fundamental collision avoidance tool in the Solent, in daylight and good viz, on a busy summer Saturday afternoon?
There are too many vessels and watercraft, large numbers of the fastest, most manoeuvrable and least predictable of which are neither receiving or transmitting AIS, the courses and speeds of all vessels are too prone to abrupt and significant change, and the situation too dynamic for devices which present only a partial representation of that complex dynamic to be of value.
It's a head up, eyes out environment.
Indeed!
But sometimes the Mark I eyeballs just don't catch the collision risk target. Here the target was coming right out of the sun. Sometimes with the best watch in the world, you just can't see. So AIS can really save your bacon on occasion. Not as a substitute for a sharp visual watch, but occasionally crucial supplement.
