I have a question regarding tacking on top of another boat that was raised at a regatta I did recently.
It was towards the end of the first beat, I was on starboard and a boat was coming in on port. I wanted to tack over to port as well but wanted to make sure he was behind me before doing so. I called starboard and he ducked me and then I tacked as soon as he had completed his duck so that when I tacked he couldn't hit me but this meant I was taking his wind. After the race he asked me at which point I was allowed to tack after he ducked me because he thought I couldn't tack immediately and had to give him space to have clear wind whereas I thought I just had to allow him to complete his manoeuvre.
If anyone knows the answer to this could they please let me know?
