Cruisers were given a sneak peek at American Cruise Lines’ seventh riverboat as the vessel was tugged out of the shipyard in Maryland, USA this week.

Carrying 150-passengers, the new unnamed paddlewheeler is scheduled to launch in March 2015. She will join the line’s Queen of the Mississippi for itineraries on the Mississippi River.

So far, the line has joined the ship’s two hulls into one piece. Over the next few weeks she will receive an upper deck before undergoing trials.

“This is a significant milestone in the construction process and also for American Cruise Lines,” vice president Timothy Beebe said.

“We look forward to introducing yet another new paddlewheeler on the Mississippi River.”

American Cruise Lines has also signed on for the production of three other riverboats.

The second newbuild is scheduled for a later 2015 launch and will join Queen of the West in the Pacific Northwest on the Columbia and Snake Rivers. She will carry 175-passengers.

“The Columbia River has not seen a new riverboat in many years,” Mr Beebe said earlier this year.

“The new riverboats will offer the finest experience available in these regions [Mississippi and Pacific Northwest], while maintaining the historic feel and authenticity of historic American river cruising.”
