At some point in the multitude of upgrades for our
Raymarine e series chart plotter, I was able to use True
Wind Speed and True
Wind Angle using SOG (GPS Speed, no paddle wheel). A later update "fixed" this so it doesn't
work that way anymore.
So I get that it won't be entirely accurate, but it would be a closer approximation than having nothing at all. Now they've added lay-lines, but it appears these are totally disabled without speed thru
water.
I've got my PC setup on
NMEA, could I get my PC to listen to
NMEA and repeat the speed over ground as speed thru
water, to trick my
raymarine in to giving me TWA/TWS/Laylines?
