First Degree Fluid Rowers

Water has unique “cube rule” physical properties, which means that to go twice as fast through it requires 8 times the effort!

Every competitive rower knows the feel of the cube rule, and just how tough it can be to squeeze that tiny extra bit of speed out of the boat in the race to the finish line.

The internal surface design of our patented twin cavity tanks means that there is no slack, no slippage, no flat spots, just full on resistance, in an instant, always there for you at the precise moment you want it- you set the resistance level at the stroke speed you want. So as the athlete increases workout intensity, the Fluid Technology resistance unit responds instantaneously.

FEATUREFLUID ROWERSOTHER WATER ROWERSAIR ROWERS
System DesignPatented twin tank with triple bladed stainless steel impeller to create variable water resistance rowing.Single tank with two blade plastic impeller.Chain driven internal flywheel fan with airflow interaction.
Tank PerformanceInternal baffles maintain resistance while providing a realistic on water rowing feel and sound.Smooth walled internal tank allows water to accelerate as it free flows without respect to length and rate of stroke.Air rushes noisily through the fan blades as the metal chain is driven with each stroke.
Tank EngineeringTwo-part tank joined by durable tank seal and screw fixings.Two-part tank glued together.There are many inexpensive imitations. As dust gets sucked into the machine’s vents, the performance characteristics change.
ResistanceLevel can be changed at the turn of a dial for multi-user interval training.Water must be manually added or removed to change level.Very little ability to change resistance ±10% at any given stroke rate.
Stroke ProfileConstant catch on initial pull with tank baffles holding the resistance during second half of the stroke to produce a more realistic on-water rowing feel throughout entirety of action.Resistance typically peaks at around 35% of the stroke pull and falls away as water freely accelerates within the tank. Resistance does not increase proportionately with speed of the pull-through.Resistance lag at beginning of stroke followed by a rapid increase to peak resistance, which then rapidly falls away before the end of stroke. Not conducive to good stroke technique.
Force CurveAs stroke profile is more robust, more work can be comfortably achieved per stroke. Alternatively, resistance can be reduced or increased at a turn of the resistance dial.Limited ability to increase power by “pulling harder and faster” but effectively restricted as water free-flows in tank reducing actual workout intensity from perceived effort.Inconsistent stroke pull can create a high perception of ‘work’, but less effective stroke power output.
Performance MonitorComputer can be set to allow for different water levels and resulting resistance changes to calculate new outputs.Computer does not adjust to different water level so workout becomes unmeasurable other than at one set water level.Extensive computer, but display seems to ignore registering considerable resistance lag at beginning of every stroke pull

One Tank,
Two Chambers

The patented Fluid Technology variable resistance system makes ingenious use of a twin-chamber tank.

Water can be transferred to and from the two chambers by means of a lever or dial operation. Water in the outer chamber provides resistance to paddles when rotated by the pulling force of the user. Any water in the inner “passive” chamber does not provide resistance. Thus the resistance can be varied through changing the water level in the outer tank and the effort of the user.

Fluid Rower Minimum Resistance

Minimum Resistance. Here most of the water is in inner (passive) chamber
The inner chamber purely provides passive storage of water.

So there is less weight of water to move in the outer (active) chamber.

The position of the indicator determines the relative levels between the two chambers.

Fluid Rower Medium Resistance

The water levels are even between chambers and this gives Medium Resistance

Fluid Rower Max Resistance

Here most water is in outer (active) chamber. The maximum weight of water gives
Maximum Resistance
