1. It is well recognized that Oracle was having serious
foiling stability difficulties at the outset of the regatta and that their
performance could not match that of ETNZ.
2. Half way through the series it was acknowledged that
Oracle had fitted an automatic control to their hydrofoil trim, and that this
modification was approved by the measurement authorities.
3. Since this modification Oracle’s performance has almost
unbelievably improved. This has been “explained” by skipper Jimmy Spithill as
being due to the superhuman efforts of the crew to improve their handling
skills. However, in view of the intensive training Oracle were able to do, prior
to the regatta, with their highly skilled team partner, it seems unlikely that
only now have they discovered the “magic bullet” they clearly have. It is much
more likely to be the result of the modifications, possibly enabled by their
surprising decision to use their lay day card and the subsequent lucky
postponements.
4. It must be remembered that this is the first time that
this contest has been sailed by yachts “flying “ on Hydrofoils and it is
probable that new and different criteria should have been applied.
5. In the aeronautical world it has long been known that the
stability of swept wing aircraft can rapidly be lost by uncontrolled yaw leading
to a dangerous situation known as “Dutch Roll”.
6. A device known as “Little Herbie” was developed during
the commissioning of the Boeing 747 Jumbo Jets over 40 years ago, to overcome
this tendency. Little Herbies, or “Stability Augmentation Systems” (SAS) as
these are now designated, are equipped with sensors such as Accelerometers and
Gyros which can detect and instigate corrections to stability with a speed and
accuracy which exceeds the ability of even experienced airline pilots. They are
therefore now installed in virtually all swept-wing aircraft.
7. The “legality” of this device has been justified and
accepted on the basis that it does not actually “drive” the trim of the
foils…..this is still performed by the muscle power of the crew, via hydraulic
linkages. That may be so, but the device, using its sensing and directives, has
been described as “automatic”. This implies that the trim of the foils is
determined by what can only be described as “superhuman” technology. If this
technology has been used to overcome the foiling stability difficulties of
Oracle it will have enabled the use of higher speed/lower drag foils which the
crew would otherwise be unable to manage. This would give a significant speed
advantage during foiling. This has been clearly in evidence since the
modification. Improvement in stability and speed has been staggering.
8. The high speed/low drag foils do have a downside in light
conditions where, due to their lesser lifting characteristic, foiling is
difficult or impossible. This was also clearly seen in the abandoned Race #13
when ETNZ were only 4 minutes from the finish, with a lead of over 1000
metres.
9. ETNZ appears to have worked within the constraints of
accepted yacht racing rules and the special America’s Cup 2013 racing Rules to
achieve foiling with these craft. This has been at the cost of using foil
characteristics and controls which can be successfully managed by a skilled crew
while having to make some concession to pure speed.
10. Although there is risk of being derided for being a
“poor loser”, or a “bad sport” it cannot go unnoticed that Team Oracle have
already been penalised for cheating, that previous Defenders have been noted for
sailing very close to the wind of rule compliance. The recent outpouring of
bluff and arrogance from Jimmy Spithill may well be part of a plan to trail red
herrings and to draw the attention off the real technological reason for their
quite literally astounding comeback.
11. The question is whether the use of a device which can
enhance performance in excess of that achievable by human endeavor should be
allowed in a sporting contest?
12. Is this grounds for protest? At least we should all be
aware that this is how desperate sporting entertainment has become.
