What is the name of a shallow boat for fishing?

A drift boat. I have only seen these boats on rivers in Montana, but I'm sure they are used just about any where. The boat is launched at the starting point, one man controlling the craft with oars while the second man fishes. When they reach their stop point the craft is taken from the water, and loaded on the trailer, that had been left at this site previously. They then return to their start point and pick up their second outfit.
