Protest Submitted

I was on the line with 30 seconds to go and boat 3015 tacked onto port, I proceeded to call starboard and boat 3015 ran into to us, I had no way of avoiding as I had boats above me that were head to wind, I was forced to back out and lose my place on the line, I called protest multiple times but boat 3015 failed to complete their turns during the race. Also At no point during the final minutes of sequence were we on port. Our sails remained filled on starboard whilst 3015 sails were filled on port.
