intereating how the mainsail track is right up to windward. at best i have the boom amidships on our boat and now wonder if i am not trying hard enough.
But your keel doesn't cant. Maybe the pivoting point for the boat follows the keel to windward, so they need to move the centre of effort to match.
Just a thought.
The boat on the left was in the process of tacking and had their sails aback. Equinox should have luffed up to clear the other boat and then lodged a protest. Less spectacular but certainly less expensive.
Is the boat on the left flying a protest flag from an earlier incident or is that a red 'class' flag?
