ditto. while he is tacking he has to stay clear. once he is on his new tack he has rights even if he is is dead in the water. i would say that once he tacks his jib he is definitely on the new tack. since you missed him you would seem to have had room to tack or duck unless you had to execute a crash tack to avoid him. if you did then you can protest. if you were going a lot faster could you not have driven off under him, pinched up and cut him off? where was the 2 boat circle?
