The Water Rower rowing machine is unsurpassed in terms of design refinement. Its patented WaterFlywheel design emulates rowing like no machine before it. Smooth, silent and storing conveniently upright the Water Rower is perfect for any user and in any environment.The Water Rower's unique patented WaterFlywheel has been designed to emulate the dynamics of a boat moving through water. When rowing the workout is generated by overcoming the effect of drag as the boat moves through the water. So with the WaterFlywheel the workout is generated by overcoming the effect of drag as the water moves past the tank. When rowing faster you move the boat, the greater the drag and the greater the intensity of exercise required to maintain your speed. The limit to the speed you can maintain is you, your physiology. Not the machine. Because the Water Rower's precision sprag clutch engages the instant the handle is pulled there is no jerkiness or jarring at the beginning of the stroke. Because the Water Rower's frame is wooden much of the machanical vibration tyipical of other exercise machinery is dampened. Because the Water Rower's patented WaterFlywheel uses the same physical dynamics as rowing, its operation is equally as peaceful. Simply pull the handle and you are greeted with the sound of surging water. The noise, while not silent, is soothing to the ears and is far from intrusive. The Water Rower's wooden frame also assists in dampening out any noise or vibration, there is no metallic clanking, just the soothing sound of running water, making the Water Rower the quietest rowing machine ever. Designed with an obsession for detail, the Water Rower is unmatched by any other fitness equipment. The overriding design philosophy of the Water Rower has achieved "beauty by simplicity". Every detail has been resolved to compliment the overall appearance and performance of the machine. Dimensions: 83"L x 21"W x 19"H Warranty: 3 Years Home, 1 Year Commercial
