Just saw this on TA: "Posted on: 10:43 am, today Save My son was one of the tourists aboard and he said the boat wasn't overfull. He said the back of the boat started sinking first and he was (fortunately) at the front. His guess was someone just forgot a plug. He didn't mention any noise. My (uneducated) guess is that the noise some heard was the engine being shut down when the crew realized they were taking on water. There evidently was some panic. His description was "It was like something out of a movie." He said he will stick to shopping and sunning for the rest of the visit."
