The model E’s seat stands 6 inches higher. And while the model D’s monitor rests on an adjustable arm, the E’s sits on unbending metal. These few technical differences do nothing to impact ride feel. We recommend the $200-cheaper model D as the best buy, but the Concept 2 E will appeal to anyone who values a higher seat and more solid construction.
Originally made from wood, shells are now almost always made from a composite material (usually a double skin of carbon-fibre reinforced plastic with a sandwich of honeycomb material) for strength and weight advantages. FISA rules specify minimum weights for each class of boat so that no individual team will gain a great advantage from the use of expensive materials or technology.
Wood is used for its unique visual appeal, but also for its ability to absorb sound vibration for smooth, quiet operation, as well as it's stable longevity. The Club edition rowing machine is handcrafted in solid ash wood and stained for color. It has been designed for high traffic or commercial areas, and its black rails have been styled to prevent scuffing. The other wooden components are finished in an attractive rosewood which is more resistant to soiling than the Natural model. Each machine has also been hand finished with Danish Oil and Urethane for protection.
The Concept2 Model D Indoor Rowing Machine includes the excellent PM5 monitor that provides all vital data. It can display your workout performance in two ways. You can choose to see your workout in total distance and time, or as “splits”. Splits is a way of seeing how your pace is varying along two set points. Either way is useful, but splits give you more of a “real-time”, in the moment calculation of how you are doing.

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.
