My wife and I will also be in that area in late April/ May. From Ft Lauderdale to Exumas and back, making all the usual stops along the way. We were hoping to bring some tanks along and do a bit of diving as well, but I've had a really hard time finding anywhere that fills tanks for private boats. It seems that there is a place in Bimini that may fill from private boats, but not many choices in New Providence or Exumas. It seems the dive ops pretty much just cater to the typical "fly in" divers. I did send an email to Stuart Cove, but I don't think they will want anything to do with me coming in their Harbor with my boat to fill our tanks.
