101-year-old ship still working the Great Lakes

The St. Marys Challenger is a 101-year-old cement carrier that is still plying the waters of the Great Lakes.

Challenger was christened as the William P. Snyder when originally launched in Detroit. Over the years, the ship also was known as the Alex D. Chisholm, Medusa Challenger and Southdown Challenger.

The ship is currently known as the St. Marys Challenger and holds the honors of being the oldest lake boat still trading on the Great Lakes.

Powered by a steam engine, the Challenger was launched in 1906 - six years before the RMS Titanic set sail on its doomed maiden voyage.
