Have you seen the SR260/SR261 from Smart Radio? It is a
receiver/transmiter, but not a "full AIS Class A/B" and do not have
oifical homologation yet, but can save lives.. I am waiting the AIS
support on Garmin chart ploters (pheraps this month?) to buy a complete
package (AIS receiver/transmiter, user friendly low 12V consumer, color
Gps/Chart/Ploter, not a laptop PC).
