I am very happy that many people reply my question which was placed
only in order to remember the manufacturers that there are many users
focused in AIS and needing AIS. I think that the big enterprises are
not very focused on commercial products with AIS, and may consider AIS
a mere fancy for some. I think that Gps/Plotter/Vhf/Ais will be the
future, but it seems that it will be much late than sailors desire.
