Divetech boats will leave from Cobalt's dock, Depends on wind and water current . That includes depth of water near dock. Everything must be perfect for boat to leave from there.This past Summer We were there,July in fact, boats left from there alot. If you go to divetech, You should ask Greg about the boats from CC. He keeps a close eye on all the details. As for Turtle Reef the car thing can be a pain, but divetech will transport you to and from. If you do a night dive From Turtle Reef and they transport you, And they Guide you on dive,A staffer can lock valubales in shop, or the van. Both dive sites was major fun. Have fun, Turtle gal
