Fetch is the distance over which the wind interacts with the water surface to creates waves. The longer the fetch the bigger (higher) the waves are. If the shore (green in the diagram) is a hill, there will be a wind shadow which gives protection from the wind, but even if the shore is flat as a pancake and gives no protection, the waves become progressively smaller as you for upwind to the shore. Thus, rowing upwind toward shore is always an escape from waves.
One of the most common brand of ergometers is Concept2.[33] The company offers multiple types of models, including the Model D, Model E, and the dynamic rower. An updated Rowperfect brand of dynamic rowers, RP3, produces ergometers that more naturally mimic the feel and resistance of rowing in a shell on the water. It additionally, shows a dynamic force curve of power that provides the rower with detailed information about their stroke which they can use to improve technique and get stronger.[34]
Floating Heel-Rest Design: The Rowing Machine's footboard incorporates the all-new Floating Heel-Rest design. The cup of the heel-rest follows the heel as it rises from the footboard providing stability and comfort from the beginning to end of each stroke. The heel-rest position is adjusted simply by pressing the central button to disengage the lock pins securing the footpads.
In sweep or sweep-oar rowing, each rower has one oar, held with both hands. This is generally done in pairs, fours, and eights. In some regions of the world, each rower in a sweep boat is referred to either as port or starboard, depending on which side of the boat the rower's oar extends to. In other regions, the port side is referred to as stroke side, and the starboard side as bow side; this applies even if the stroke oarsman is rowing on bow side and/or the bow oarsman on stroke side.
