It also serves as an inspection boat for the Mississippi River Commission (MRC) during a high- and low-water inspection trip each year. Commissioners hold meetings at river towns in the boat's hearing room, which can seat 115 people. Its dining room has a capacity of 85 people. The boat has 22 staterooms and can handle 150 passengers. The Corps also uses it as a "giant floating ambassador".
