AIS rocks!

AIS - Automatic Identification of Ships - gizmology with attitude and relevance. Big ships (>300 DWT for the techies) are required to transmit AIS data on VHF radio (Ship's GPS position, likelihood of collision, name, MMSI, course, speed, destination.....lots more) and carry expensive equipment that reads, integrates and plots the data from other ships using GPS so everyone has a position for everyone else, plus a lot of other information. Us little boats can clock in with the right gizmological goodies and use the data and it's brilliant. If it's working! Berri's AIS black box died somewhere between Lisbon and here but we now have a better and, I hope, more durable one courtesy of Udo. Pics are of Udo installing the box and two screen dumps of the data - first one shows the list of ships whose data we were receiving plus the specific data from one ship, in the right hand column. Second one has the plot of the Cape Town harbour with the ships we were receiving in their correct positions.

And Pete, fixing the leak over my feet at the same time.
