Talk to Drshark. He used to live down there. I think he will probably tell you to go down to Punta Aventura _ I think that's what it is called. I've fished out of there a couple of times, and it was ok- biggest problem was it was the wrong time of year.
went there two years ago and went out of acumal on a panga , 2 boats we had 5 dorado in less than 2 hours on 1 boat had to come in because girls got sick. buddy just got back a month ago and they had a 50# wahoo and 3 dorado with capt riks good luck! it is a great place.
