I suppose if you want to get pedantic about it, you could argue it was the market discouraging it not the govt but the point is when they first came out, no one was suggesting these for small pleasure craft and there was a lot of concern expressed about pleasure craft signals cluttering up the system (we still get that complaint now from folks who can't handle an occasional docked boat transmitting that it is sitting quietly in it's slip).
Class B was the eventual outcome but by then production of recievers was already happening creating the split between recievers and fully functional units. I'm guessing in the next 5 yrs the recievers will fade away as no new development goes into the recievers and the economy of scale catches up making the differential cost negligible.
It was always the intention to develop a solution for small( well smaller) craft, initially this was to be SOTDMA based, but a simpler version was then developed. planning for AIS
stated in 1990, so its some time ago, the IMO mandate for class A was only issued in 2002 and class B followed in 2003.
The main issue was the slow update by the leisure industry of full class B, and this development was hindered by the red herring that is receive only AIS
. The class B development was then furthered hindered by the ridiculous delay by NMEA
in sorting the PGNs , especially the static data ones.
I don't think Ive seen any cohesive issue from the marine
industry about leisure AIS.
