A Hewes boat can run in very shallow water, often floating in well under a foot. For example, the Hewes Redfisher 21 draws only about 14 inches of water, and smaller Hewes models float even shallower. That shallow draft is the whole point of a flats boat: it lets you reach backcountry spots and fish over flats that bigger boats simply cannot get to. Keep in mind that how shallow any Hewes can run also depends on how it is loaded and whether the engine is trimmed up. Shallow draft is one of the main reasons anglers choose a Hewes.
