The Chineseyuloh^[8] (Chinese:摇橹; pinyin:yáolǔ; Jyutping:jiu⁴lou⁵) is a large, heavy sculling oar with a socket on the underside of its shaft which fits over a stern-mounted pin, creating a pivot which allows the oar to swivel and rock from side to side. The weight of the oar, often supplemented by a rope lashing, holds the oar in place on the pivot. The weight of the outboard portion of the oar is counterbalanced by a rope running from the underside of the handle to the deck of the boat. The sculler mainly moves the oar by pushing and pulling on this rope, which causes the oar to rock on its pivot, automatically angling the blade to create forward thrust. This system allows multiple rowers to operate one oar, allowing large, heavy boats to be rowed if necessary.^[9]

Single-oar sculling can occur in competitive rowing when a sweep boat is locked-on at the starting line of a race and the coxswain needs to adjust the direction the boat is pointed in. In order to accomplish this without pulling the boat away from the starting line, the coxswain will command a rower in the bow half of the boat to "scull" the blade of the rower in the seat behind them. By maneuvering the boat in this manner, the coxswain will be able to adjust the point of the boat without disconnecting from the starting line.^[10]

Modern sculling vessels come in many shapes and sizes and range from being traditional cargo barges and fishing boats to being basic or fun modes of transportation. Either way, they are typically most identifiable by their often side-mounted, unidirectional oar-locks and oars, which allow the operator, ideally, to use one hand to operate the boat. One of the greater attractions to these vessels is that they are easy and inexpensive to operate.^[11] The typical modern barge-shaped and "flats"-style boats are still made from materials ranging from a variety of wood products, fibreglass, reinforced concrete, or metals.^[12] Some are simply converted old motor boats. The traditional advantages of the smaller sculling craft as a hunting boat are that the operator can quietly sneak up upon fish and fowl without splashing or otherwise disturbing the still calm of the water. New commercially available single sculling hunting boats use very light materials and slick shapes for greater speeds and responsiveness.^[13] Notably, the oars of the more modern single sculling vessels are now more typically mounted to pivot off one side of the boat. The operator can face either forward or aft.
