I am heading down to Playa del Carmen on the Yucatan in April ’06 and have been scouring the net for information regarding freediving and spear fishing. I have turned up decidedly little. It seems that most dive outfits require the use of life vests while snorkeling(@$#*~!!!):vangry and don’t recommend swimming too far out from shore due to heavy boat traffic. While sport fishing is big they all seem to frown on spearfishing. Does anybody know anything about freediving and spearfishing the eastern Yucatan?
