REST IN PEACE: Marvin Creamer, a Mariner Who Sailed Like the Ancients, Dies at 104. “His expertise helped him become a history-making mariner, the first recorded person to sail round the world without navigational instruments. His 30,000-mile odyssey, in a 36-foot cutter with a small crew, made headlines worldwide on its completion in 1984. . . . Professor Creamer continued sailing well into his 90s. In later years, he owned a boat that came equipped with global positioning technology. He did not know how to use the technology, he said, and had no intention of learning.”
