"the captain and first mate were rescued first"
I would like to make a correction for that statement because people would think wrong.
The captain called the company and ask for help, than he left the boat before it sunk. Than he swam to the shore.
The company gave me a call to help them out with our resort's boat. He sent his crew right a way to my resort, we went there and rescue 3 tourists and the dive master (in this order).
