Look for a "bluetooth to serial converter" in google. They are pretty common in the industry now, and should cost under $200. You hook the output of the AIS to the transmitter, and the software creates a virtual bluetooth serial port on your machine. If you have a NMEA combiner then it might make more sense to put the converter onto it so that you could wirelessly see your other navigation data. If you want to spend a bit more money, a couple of companies make NMEA combiners that support bluetooth. Combiners are handy things if you are planning to expand your navigation network in the future. I would probably go this route myself, since it would mean that I could have both the reliability of a hardwired connection (to my chartplotter) and the convenience of a wireless connection to my laptop.
