Function plays a large role in defining good design. When designers look at an object, they don't just consider its aesthetic appearance; they should also challenge it to be more versatile, to respond to the user's need, or to achieve its purpose more elegantly. Good design has the capacity to solve problems that sometimes we didn't even know we had. This is one of the ways design touches and enriches our everyday life.
The advantages with air rowers is that there is smooth action; there is only small wear and tear to its mechanism; its automatic feature adjusts according to your rate of strokes; and there is a wide range of the resistance readily available in replicating the feel of rowing through the waters. The only disadvantage of this machine is that it tends to be noise indoors.

The machine was easy to put together and worked well mechanically. The problem is the electronic monitor. The strokes/min registered as double the actual pace, and the distance registered as 1/10th the actual distance. I contacted customer support via email and their response was slow and inadequate. I am returning the machine and plan to buy a WaterRower.
Single, and double sculls are usually steered by the scullers pulling harder on one side or the other. In other boats, there is a rudder, controlled by the coxswain, if present, or by one of the crew. In the latter case, the rudder cable is attached to the toe of one of his shoes which can pivot about the ball of the foot, moving the cable left or right. The bowman may steer since he has the best vision when looking over his shoulder. On straighter courses, the strokesman may steer, since he can point the stern of the boat at some landmark at the start of the course. On international courses, landmarks for the steersmen, consisting of two aligned poles, may be provided.
Unfortunately, the direction of water movement at the top and bottom of the wave (thick arrows) rotate the boat in the direction you don’t want to go. As you realize this you try to pull your down-hill oar up out of the water, but this just pulls you over more in the bad direction. I spare you, gentle reader, a picture of the result. As the wave carries your boat up to a crest you try to lean into it to keep the boat level, but it’s natural to also push down on the down-hill oar to help.
If you are accustomed to the natural catch and feel of on-water rowing, your rowing technique will immediately appreciate the Apollo’s unrivalled emulation of a boat gliding through water. FDF’s patented twin tank design generates a smooth uniform stroke, including no lag of resistance at the catch and continued resistance all the way to the finish.
Balanced Tear-drop Handle: The handle of the WaterRower M1 LoRise is made of aluminum for strength and lightness, with a tear-drop shape that fits comfortably into the palm of the hand to minimize wrist torque - a common cause of tendonitis. Because of its strength and lightness, the drive strap of the WaterRower M1 LoRise is high-density polyester webbing, guided by nylon pulleys. The drive strap does not wear and is maintenance-free, requiring no messy lubrication.
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.
