Which steamboat took three hours longer than the Reindeer?

This is from the 'Steamboat travel on the Mississippi'. The Enterprise was the steamboat boat which took three hours longer than the reindeer.

Explanation:

The Orleans was the first steamboat to go on the western waters. The speed was really good. Thereafter changes were made in the size of the steamboats to increase the speed. The Enterprise, which was set in May 1815 was a small steamboat which weighed 75 tons. This brought a cargo of ordnance from new Orleans and reached Louisville after 25 days.
