Although the oar can be conveniently thought of as a lever with a "fixed" pivot point in the water, the blade moves sideways and sternwards through the water, so that the magnitude of the propulsion force developed is the result of a complex interaction between unsteady fluid mechanics (the water flow around the blade) and solid mechanics and dynamics (the handle force applied to the oar, the oar's inertia and bending characteristic, the acceleration of the boat and so on).
As Stamina’s first water rower, the Wave Water Rowing Machine 1445 has all the necessities for a realistic, effective workout. Rowing on this machine feels and sounds like rowing in real life, making this a great option for those who are seeking an affordable water rower for indoor training. But even if you aren’t an avid oarsman or oarswoman, this machine truly offers a total body cardiovascular workout that’s enjoyable for everyone.
The large display console allows you to keep track of the calories burned, distance covered, strokes per minute and duration of the workout. The Newport also includes an improved seat roller design for a smoother glide. The ergonomic padded seat will keep you comfortable and encourage longer workouts while the rust-resistant rail system is made to prevent scuffing as you push yourself during an intense session.
The rowing machine itself is unlike any other on the market with its patented water filled flywheel. It is hard to exactly copy the action of a scull on the water, but the mechanics of the flywheel spinning in water comes in a close second on dry land. The fact that the water is 800 times denser than air means that there is no need for any extra resistance or dampening that you will find in normal air rowers. The faster you pull, the more resistance is generated giving it infinite variability. However, if you want to be able to practice rowing with a faster stroke, you will have to reduce the amount of water in the tank unlike an air rower where you just have to adjust the baffle.
