In the New York Surpeme Court, Justice Shirley Kornreich has released her decision which permits the use of engines to sheet sails and perform other sailing functions.
She has also called a hearing for 10 August (allowing six hours) to hear submissions on the question of BMW Oracle Racing being required to produce their Customs House Registry document 'as soon as possible' and the meaning of that phrase.
If BMW Oracle do intend have as second yacht underway, to be named USA, then the team will be in the clear, however if it is their intention to re-use and re-name BOR90, then it would seem they may have problems in the light of Kornreich's earlier ruling and threat of disqualification.

Alinghi 5 - with what some believe could be a ballast water pipe highlighted with the red arrows. To our eyes the pipe diameter appears to be too small, however the water would be fed under pressure, rather than gravity fed as with other ballast systems. - David Lenoir

The ruling on the engines was not unexpected, on the basis that provided the vessel is propelled by sails, then there are no restrictions on the technology used.
It would seem that the engine technology is not refined to be reliable (since most supermaxis use their primary diesel and not an auxiliary hung off the stern). Sail-World's information is that the grinder system is lighter (even without the engine) - the weight saving in the engine/hydraulic option coming from the reduction in crew - which some point out are moving ballast anyway. We will examine these issues in an upcoming article on Sail-World.com
While the decision will be seen in some quarters as a big plus for Alinghi, the fact is that the technology is unproven in the context of using a externally mounted engine to provide power for sheeting and other onboard systems. Supermaxis and the like do use engines for the same purpose, however these are located below decks and are reliable and known diesel technology.
Further the decision permits the use of such engines in the America's Cup, in the style of the 33rd America's Cup. However there is a lot of ancillary technology required, or that can be applied, such as the use of PLC's (process logic controllers or very small programmable computers to control various functions, and with a technology partner such as BMW, it may be that BMW Oracle Racing are in a better position to make use of Kornreich's decision than Alinghi.
Kornreich's decision opens the way for the use of computers on am America's Cup boat which can sail the boat in the same way that on-board computers can fly a plane, with the crew having more of an oversight function than direct control.
The use of PLC's and the power they can control, generated by the engine, in can obviously be used for both safety - monitoring fibre optic load sensors, and performance optimisation - replicating settings that have proven to be the optimum from hours of test.
In many ways it is similar to a Formula 1 car which can effectively be driven at its optimum from the pits, via the use of onboard computers and wireless systems - with the driver really in an over-ride role. And from this perspective BMW can bring a very useful source of proven technology to the BMW Oracle Racing campaign.
Of course, from Alinghi's viewpoint, the decision by Kornreich is crucial as their design has been moded around the used of an auxiliary and it would be very difficult to retrofit grinders into the yacht, had her decision gone the other way.
