"Tropical Dance", I believe, has some charts that were taken off new data from a new Mexican Navy survey that are suppose to be pretty accurate. My Garman 3210 doesn't support them as far as I know so I don't go in at night. When I go in during the day I save my track and turn it into Way Points so I can get out at night if I have to. You know that if it's going to happen, it's going to be pitch black so I set it all up prior to turning in for the night. I do that EVERY TIME I go into a new anchorage.
