I assumed that North would be 0 degrees, based on a scene from The Hunt For Red October "set course, 180" which was due south. A plot line from a movie with some accuracy in the real world. See kids, watching movies isn't all a wast of time.
The 30/45 degree differences were not difficult to discern. At least you didn't go for odd angles (I would have been tempted).
- The captcha can show notches in either 30 or 45 degree increments. I thought that the extra challenge of discerning between the two would be interesting, but it seems to be causing more frustration than I would have anticipated. Definitely lessons learned from the feedback here. :)
- The fastest boat direction from the wind also depends on the wind speed, and this also depends on the boat itself. You can find a wind response polar plot for the boat modeled here shown on the site's help page [1].
