I defy you to show me one panga on the coast from Cancun to Tulum that could possibly pass a Mexican Coast Guard inspection. I agree with you on one thing, stick to the cenotes. If you want a good dive op in the Yucatan, go with the ones the cave divers use.
First, Ed, sorry to hear that H10 wasn't up to your expectation and I am more sorry to hear that you didn't like Tortuga. I wonder if they dropped you in the wrong site??
Pietro is a great guide who works freelance so you may not get him next time.
As for Baracuda, that is one difficult site to navigate if you don't know where you are going.
I will defy you
