 It did not have the pulling power necessary for dredging, however, its log construction was combined with characteristics of other vessels to form the first bugeyes, a much larger and more powerful vessel.As motor power became available, watermen who were not dredging gradually abandoned sail power; also, the supplies of suitable timber were gradually exhausted.Log canoes were often converted to motor power, and new workboats (such as the Chesapeake Bay deadrise) were motored from the start and used frame construction instead of logs.
