Marlon looked away and tended to his own problems for a moment. His upper body was out of the water, but his legs were being dragged along, creating powerful suction that threatened to rip him off the tire. Inching, like a rock climber, to a slightly better grip, he was able to lift a leg out and drape it over the adjoining tire, and this both reduced the suction and gave him leverage to clamber up and get better handholds. He worked his way to a place where he was standing with one foot on the tire’s rim and reaching up over his head with both hands to grip the boat’s gunwale.
