Storage is also a plus point for the Waterrower series as they are all designed to stand upright with the tank acting as ballast for stability. In this position they only take up around two square feet. Again, great if you are planning on training in the living room. However, if you have small children, I would advise fixing the top to the wall with a hook and strap.
In addition to this, certain crew members have other titles and roles. In an 8+ the stern pair are responsible for setting the stroke rate and rhythm for the rest of the boat to follow. The middle four (sometimes called the "engine room" or "power house") are usually the less technical, but more powerful rowers in the crew, whilst the bow pair are the more technical and generally regarded as the pair to set up the balance of the boat. They also have most influence on the line the boat steers.
In the patent record, means are disclosed whereby the chain/cable take-up and handle return are accomplished without the use of a spring or elastic cord, thereby avoiding the stated disadvantages and defects of this broadly used method. One example is the Gjessing-Nilson device described above. Partially discernable in the thumbnail photo, it utilizes a cable wrapped around a helical pulley on the flywheel shaft, the ends of this cable being connected to opposite ends of a long pole to which a handle is fixed. The obvious disadvantage of this system is the forward space requirement to accommodate the extension of the handle pole at the "catch" portion of the stroke. The advantage is that, except for small transmission losses, all of the user's energy output is imparted to the flywheel, where it can be accurately measured, not split between the flywheel and an elastic cord of variable, unmeasured resistance. If a similar system were installed on all rowing ergometers used in indoor rowing competitions, consistency between machines would be guaranteed because the variability factor of elastic cord resistance would be eliminated, and this would therefore ensure that the monitor displayed actual user energy input.
