You will get this achievement during the first fishing challenge in the game. Watch your fish finder and when prompted press the
to drop the buoy. Once the buoy is in place pull the boat around, so that the buoy is in front of the boat. Press
to start fishing and press the
to cast. You should be positioned far enough away from the buoy that the hook should drop next to the buoy. You will be prompted that it was a nice cast. If not, move the boat till you get the prompt when the lure hits the water.
