Fantastic work!
I'm hesitant to ask but isn't the leeward belligerent in figure 1-3 incorrect? Atleast in part.
He flips, which is correct, but he doesn't close separation.
Perhaps the figure should show the windward belligerent turning into the wind somewhat, as a response to the leeward belligerent trying to close separation (as in figures 1-2 and 1-4).
Or would that be a wrong move by the windward ship?
