The USS Marmaton (NCC-74749) was a Danube-class runabout formerly assigned as an auxiliary craft of the USS Hainan. In 2377, Marmaton was used by Roslyn to evacuate the Hainan after Hainan was rammed by a "warbug." After the Hainan crew was rescued by the USS Ottawa, Roslyn used the Marmaton to recover the damaged Verdigris and crew from Grecon IV. (USS Baldwin: "Like the Rain")
