WHY PRESSURE, AND BEING 'BEST UNDER PRESSURE' IS IMPORTANT Absolute top pressure must be maintained at all times in order to enable small adjustments all the time, at any time. The higher the pressure, the quicker the reaction and adjustment. If you imagine standing on a narrow balancing beam, then starting to walk - you put your arms out on each side to steady yourself. You make small adjustments with each arm, as required, to keep steady to ensure you don’t fall off. This is the equivalent of what the sailors are doing - making continuous, small, reactive adjustments to steady the boat as it powers along – to ensure it does not fall off the foils. These incredible boats are more like aircraft and use systems and controls very similar to those used on an aircraft wing. Many would have seen the flaps on an aircraft wing move – which is also all hydraulically activated. Thus why you might see these boat teams associated with companies like Boeing, Airbus, etc. One of the differences on ETNZ, other than the cyclists, is Glen using a hydraulic hand control to trim the wing in and out and the twist. Other teams use a rope on a winch. Glen sits low in the boat, the cyclists are hunched over, and Peter sits positioned to look over their heads. This allows ETNZ to have less windage or drag when sailing - very important in light conditions. You often see the opposition grinders start the race bent over the pedestal grinders and later in the race when they are tired and need more air they stand more upright to grind - more windage. There is a lot of focus on top speed, which is important, however just as important is the speed of the tack or turn. If you can maintain a higher speed through the turn and stay on the foils you make up a lot of distance on the opposition. In this way, it is similar to car racing - the faster you come out of the corner, the higher straight-line top speed you can achieve before the next corner. “I was really impressed at how fast the boys were tacking the boat – something you can do when you have faith in your hydraulic systems delivering the pressure,” adds Lee. The ETNZ team handled the pressure of the race, the media and a demanding New Zealand public. But for the pressure that powered the actual boat, well ETNZ left that up to Hydraulink. Frame 04.
