Chartplotter - Course To Steer (CTS)

>...which is as the integrated systems people (because of course ability to make an autopilot track to a waypoint predates chartplotters) seemed to have ended development of their product at the "reacts to COG not matching BTW then corrects heading" stage. Rather than the next stage, which is "measure current tide using instruments, and use this to predict best heading as a starting point given current STW - then compare actual COG to BTW"

That's why I've never used a charplotter, it's technical gobolldygook ;-)
