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 coxswain (or simply the cox) is the member who sits in the boat facing the bow, steers the boat, and coordinates the power and rhythm of the rowers - by communicating to the crew through a device called a cox box and speakers. They usually sit in the stern of the boat, except in bowloaders where the coxswain lies in the bow. Bowloader are usually seen as the coxed four and coxed pair type of boat.
Assembly was challenging. One of the rails could not be attached because the embedded screw in the cross-beam was too crooked to fit into the hole on the rail. I had to place a nut on it to protect the screws and tap until it was true enough cap nut to be attached. The foot board is slightly wider than the top board. I will sand this to match when I reapply the finish. This will need to be done because the wood has a dry, ashy appearance. The wood is beautiful and mostly uniform. This rowing machine is a nice product, but the build quality of the unit I received was disappointing. I felt lucky that the gashes in the carton did not damage the product as the packaging was optimistic. The leading competitor I use at the gym seems to provide slightly more resistance. It is beautiful and useful, but with room for improvement.
Rowing is a cyclic (or intermittent) form of propulsion such that in the quasi-steady state the motion of the system (the system comprising the rower, the oars, and the boat), is repeated regularly. In order to maintain the steady-state propulsion of the system without either accelerating or decelerating the system, the sum of all the external forces on the system, averaged over the cycle, must be zero. Thus, the average drag (retarding) force on the system must equal the average propulsion force on the system. The drag forces consist of aerodynamic drag on the superstructure of the system (components of the boat situated above the waterline), as well as the hydrodynamic drag on the submerged portion of the system. The propulsion forces are the forward reaction of the water on the oars while in the water. Note also that the oar can be used to provide a drag force (a force acting against the forward motion) when the system is brought to rest.
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.
