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?
