Narrative:

During taxi out my first officer picked up the clearance from freeport, bahamas to mia. I discussed the clearance with him and it became my understanding that we had been cleared via BR64V to AR1, which I flew. Approaching AR1, ZMA asked how we had been cleared. This raised doubts in my mind so I looked at what the first officer had written and it was BR68V to AR1. In the future I plan to watch the clrncs more, as what I thought I heard wasn't what was given.

Title: NON ADHERENCE TO ATC CLRNC IN RTE FLOWN DURING AN OVERWATER OP.

Narrative: DURING TAXI OUT MY FO PICKED UP THE CLRNC FROM FREEPORT, BAHAMAS TO MIA. I DISCUSSED THE CLRNC WITH HIM AND IT BECAME MY UNDERSTANDING THAT WE HAD BEEN CLRED VIA BR64V TO AR1, WHICH I FLEW. APCHING AR1, ZMA ASKED HOW WE HAD BEEN CLRED. THIS RAISED DOUBTS IN MY MIND SO I LOOKED AT WHAT THE FO HAD WRITTEN AND IT WAS BR68V TO AR1. IN THE FUTURE I PLAN TO WATCH THE CLRNCS MORE, AS WHAT I THOUGHT I HEARD WASN'T WHAT WAS GIVEN.
