The Development of Rowing Equipment By Bill Miller This page contains information about the development of rowing equipment beginning about the end of the 18th century.
There are two forms of rowing: 1  In sweep or sweep-oar rowing, each rower has one oar, held with both hands. This is generally done in pairs, fours, and eights. 2  In sculling each rower has two oars (or sculls), one in each hand. Sculling is usually done without a coxswain, in quads, doubles or singles.
