Olympias is a reconstruction of an ancient Athenian trireme and an important example of experimental archaeology. She was subject to sea trials in 1987, 1990, 1992 and 1994, but one of the most informative was an exercise in 1987 when crewed by 170 volunteer oarsmen and oarswomen. Olympias achieved a speed of 9 knots (17 km/h) and was able to execute 180 degree turns within one minute, in an arc no wider than two and a half (2.5) ship-lengths.
November 25, 1120: The White Ship sinks. It was the Titanic of its day, a brand-new ship captained by the son of the man who had brought William I o England's shores in 1066. The captain was hungry for glory, and volunteered to bring William's grandson back from Normandy. All souls save one were lost when the oarsmen ran full-tilt onto a submerged rock. It was said that Henry never smiled again, and it certainly changed the line of succession, resulting in a long and bloody Civil War.
