Fitzgerald: When A Big Ocean Gets Small
It is a big ocean. Until you have been far into it, it is really hard to appreciate just how big. Bringing a ship back from Japan to Hawaii, I once went ten days without seeing another ship, either by eye or radar. That is a long time to be alone in the world, especially if you are moving in a straight line and at good speed.
On the other hand, you would be surprised at how crowded the ocean can get in certain places. The Strait of Malacca, for instance, divides the island of Sumatra from Malaysia. Not only is Singapore at the southern end—one of the great maritime ports of the world—but most of the shipping moving between Asia and Africa, the Middle East, and Europe, travels through this increasingly narrow, 600 mile-long passage. Every year, 100,000 ships transit this strait. By the way, these confined waters are infested with pirates and literally thousands of fishing boats. While a chart may make the strait seem wide, the passable channel for big ships is only a couple of miles wide.
