Local thieves had made the error of picking on Obsession, anchored in a secluded cove in the Golfete known as Gringo Bay, about four miles from where Ithaka is right now. Carel and his wife Bea were aboard, as well as Bea's elderly parents, who were visiting from Switzerland. At about sundown, Carel heard a knock on the side of the hull. He hopped into the cockpit to find three guys in a cayuco asking for gasoline. The policy on Obsession is that no one is allowed on board without an invitation, but two of them started to climb on. Carel tried to dissuade them with words, when one man grabbed his arm, and he saw a gun in the hands of the second. Bea could hear that there was a problem. She took the pepper spray, which was near the companionway, reached her arm out and, unsure of how to use it, began spraying a wide arc in the direction of the voices. She hit the two boarders, one of whom twice fired his nine-millimeter gun into air, before both fell back into the cayuco and fled. "I got a good dose, too," said Carel. Bea's parents, eating dinner at table, didn't know anything was wrong until they heard the shots.
