Watercraft rowing

Rowing is the act of propelling a boat using the motion of oars in the water, displacing water, and propelling the boat forward. The difference between paddling and rowing is that rowing requires oars to have a mechanical connection with the boat, while paddles are hand-held and have no mechanical connection.

This article deals with the more general types of rowing, such as for recreation and transport rather than the sport of competitive rowing which is a specialized case of racing using strictly regulated equipment and a highly refined technique.

In some localities, rear-facing systems prevail. In other localities, forward-facing systems prevail, especially in crowded areas such as in Venice, Italy and in Asian and Indonesian rivers and harbors. This is not strictly an "either-or", because in different situations it's useful to be able to row a boat facing either way. The current emphasis on the health aspects of rowing has resulted in some new mechanical systems being developed, some (such as the Rantilla rowing method) very different from the traditional rowing systems of the past.

Rearward-facing systems: This is probably the oldest system used in Europe and North America. A seated rower pulls on one or two oars, which lever the boat through the water. The pivot point of the oars (attached solidly to the boat) is the fulcrum. The motive force is applied through the rower's feet. In traditional rowing craft, the pivot point of the oars is generally located on the boat's gunwale. The actual fitting that holds the oar may be as simple as one or two pegs (or thole pins) or a metal oarlock (also called rowlock - "rollock"). In performance rowing craft, the rowlock is usually extended outboard on a "rigger" to allow the use of a longer oar for increased power.

Sculling involves a seated rower who pulls on two oars or sculls, attached to the boat, thereby moving the boat in the direction opposite that which the rower faces. In some multiple-seat boats seated rowers each pull on a single "sweep" oar, usually with both hands. Boats in which the rowers are coordinated by a coxswain are referred to as a "coxed" pair/four/eight. Sometimes sliding seats are used to enable the rower to use the leg muscles, substantially increasing the power available. An alternative to the sliding seat, called a sliding rigger, uses a stationary seat and the rower moves the oarlocks with his feet. On a craft used in Italy, the catamaran moscone, the rower stands and takes advantage of his body weight to increase leverage while sculling.
