I know there was some discussion about Furuno
, and have searched the Wiki.
Thanks very much.
It depends on what, exactly, the friend wants to do with the waypoint.
As for digitally transferring a waypoint to a Raymarine chartplotter
, I suppose it depends. Some converters (like the one I have) are one-way only - they'll transfer from Seatalk
to NMEA and output the NMEA result. But they won't go the other way. I believe there are others that go both ways, in which case it would depend on whether the Seatalk chartplotter
is set up to actually receive a waypoint from another source and knows what to do with it. I don't know enough to answer this.
However, I do know that my Raymarine ST4000+ autopilot
has NMEA inputs and can act on the appropriate NMEA sentences that it receives. OpenCPN
sends DTW, BTW, XTE, and SOG information to the autopilot
, and upon putting the autopilot into "track" mode it will navigate the boat
to that waypoint. If I right-click and select "Navigate to Here", the boat
goes there. Similarly, if I activate a multi-point route in OpenCPN
, OpenCPN sends this information to the chartplotter, one waypoint at a time, with a manual "acknowledge" required before advancing to each next waypoint. If this is what your friend means by "sending a waypoint to Raymarine," that it is definitely possible with the correct model of autopilot and the correct setup.
My autopilot also has a "wind vane" mode. It will receive wind transducer
data though the NMEA inputs and maintain a constant angle to the apparent wind
. I have not tested this yet - it's a project
for this spring.
