My response to Chuck got scrubbed again.. I need to stop trying to send from the phone...
Here goes:
The laylines are not necessarily set at any particular angle.. That's the
genius of it. It analyzes how you are pointing / running relative to
apparent wind speed, current, tides, direction, wind shifts, and boat speed
then does the trigonometry for the layline angle that gives the optimal
tack / jibe point to max-out your vmg to waypoint.
During that race I followed it precisely, gained 2 tacks over 5 miles..

That zeus sounds interesting. Would be nice to have the laylines. Are
they set at 45 dgrees? Can you set them lower?
