According to my research, the Titanic's top speed was 23 knots.
You might also be interested to know that the ship's length was 882 ft, and the giant vessel weighed 46,328 tons.
Most people hadn't seen anything like it at the time, mainly because there weren't too many people who had $7.5million ($400 million of today's money) to blow on a ship.
