Hi all,

Sailing season has ended for me, next week my boat is on land and I'll
prepare it for winter.
So, now begins the "silly sailing season" when I get to prepare for next
years sailing.

This year we had some semi long trips with legs of up to 80-100 nm and a few
weeks at sea. While sailing I have my plotter right at the wheel and at the
moment I lack AIS information there. We did cross the bigger shipping lanes
and of course had to keep a sharp lookout, as always.
I will connect an AIS receiver to be able to see the other ships
earlier/better. The bigger ferries do 30 knots so in a few narrow passages I
would have liked to see where they were going earlier. But, I would also like
to see other boats that use aprs on my plotter and of course I would like to
have pskmail integrated too. So, I built an aprs to ais gateway. That way I
can have both AIS, APRS and PSKmail tracks on my plotter. It converts APRS
pos messages into NMEA AIVDM with AIS Payload containing AIS message type 1
(Position report class A) which any AIS capable plotter must handle. I intend
to add type 5 also to get some more data across. I have it on a PC now but
that won't do on the boat, I'm thinking arduino to save power and size.
So, I just wonder if that kind of thing could be interesting for others with
boats? A small box that lets you connect AIS and APRS sources to a dedicated
plotter or software (OpenCPN for PC or android works fine btw).
