    CTS

    Is there a way to display the Course to steer for a leg based on the GRIB/tide data, as opposed to heading to steer which is based on the current instrument data, as I understand it?  I.e. On this leg steer 180?

    Re: CTS

    I might be missing your question, but what is the difference?  Assuming your next waypoint has been set through an optimisation process, or is a corner of the course, how does a change over time alter that point?  If there has been a significant change in weather, re-run the optimisation altering whatever of your weather inputs are now different than the grib (e.g. Settings/Optimal Advanced/Wind).  And I may be missing the point of your question.

    If you have a - in that example, see screenshot - first a westerly and later a easterly going tide; there would be - theoretically - one CTS. I wonder if that is then the 183°M?
