I have AIS fitte.
We have a full class b tarnsponder fitted to the boat. We use the AIT250 from MES. In our ickle office we have the Easy AIS and Easy Split from Echo Pilot.
We use the system for two main reasons:-
1, so the we can see and be seen by all the commercial vessels when we are out and around the Goodwin Sands or anywhere.
2, anyone in the office can see where the boat is and or track it at anytime ( we are normally never out of AIS range of the office.
Both are interfaced into a plotter both Standard Horizon. Have to say works really well and on the back of it a good number of locals have now and or are fitting it.
I know there is all this "big brother" stuff but IMHO its a great add on safety feature and getting cheaper all the time.
