At 207’ in length and 60’ in breadth, the boat was designed to carry 3,200 passengers comfortably on her five decks. Her beautiful interiors were created in collaboration with the painter and designer Louis O. Keil. The boat is adorned with mahogany paneling, etched and leaded glass, gilded moldings, a grand staircase, and an innovative open-air ballroom. Columbia’s massive 1,200-horsepower triple-expansion reciprocating steam engine, surrounded by viewing galleries, will become an unforgettable demonstration of early steam technologies for visitors. Laid up and minimally maintained for the past 15 years, the boat has suffered an accelerating decline in her condition. However, unlike many historic vessels, Columbia is a good candidate for restoration. Her modern structure gives her a unique advantage.
