Salem had grown up in the desert. He dared not to claim that he knew everything about the desert, but perhaps he knew at least 70 to 80 percent of its happenings. However, it was a vastly different story with the sea. He knew little about the sea. Yet he didn't feel that he needed to know more. For Salem, as long as he could swim in the waters, he was satisfied. Under the guidance of his cousin, he'd learned to swim in a few hours. His cousin was extremely proud of his remarkable learning abilities.
Salem didn't plan to work on an ocean liner and merely did surfing near the beach. That probably didn't warrant a deeper understanding of the sea, did it?
