Released boat, killed sharks, but cant figure out how to get boat, or go back around to the hole mentioned in the walkthrough. See a spot where it looks like i can jump up, but cant jump that high.
 
 Imust be missing something obvious
  
 
  
  
    Face the ornate door while in the water, then turn left. There is a ledge you can climb onto. Then, jump and grab onto the next ledge.
 
 It's the same way you go to get to the hole the first time.
