AIS

AIS is a really cool technology. It's a bit like the transponders used on aircraft. We have AIS class B onboard which means that we both receive others info as well as transmit our own.
All the blue polygons are AIS targets. The purple shading is the radar overlay. White is water and Orange is land.

There is so much shipping traffic here that it's like an extremely slow game of frogger. Each "jump" takes 20 minutes, hour after hour after hour.

Had trouble staying awake but managed to avoid hitting anything or worse yet having anything hit us.
