Their massive, 27m-long multihulls, with 50m masts, estimated to have cost tens of millions of dollars each, are due to begin a best-of-three race event on February 8 to contest the 33rd America's Cup.
But even now, the rival syndicates are mired in litigation which could postpone the event.
The deadline for setting up graphics coverage passed earlier this month for Animation Research Ltd, the pioneer of America's Cup graphics coverage with its Virtual Eye, but a late call about a fortnight ago, from organisers, prompted the company to send three staff members and equipment to Spain last Saturday.
Seven staff are expected to be in Valencia when racing begins.
Animation Research managing director Ian Taylor confirmed yesterday a contract with the organisers was in place.
Mr Taylor said getting ready in time for the race will be "one of the biggest [graphics set-up] challenges we've had".
"Not much is known about Oracle and Alinghi.
"They have the biggest, fastest boats to contest the America's Cup and it takes place on the largest ever course," Mr Taylor said.
The other Dunedin-based company involved is Igtimi Ltd, which has been designing and supplying electronics hardware and software for Animation Research's Virtual Eye graphics program since 2008, including the Louis Vuitton series in Auckland, recent Med [Mediterranean] Cup and other Vuitton World Series regattas.
Director Brent Russell will head to Valencia shortly, to install radio and satellite up-link technology for his u-Track telemetry system, which provides the data for the Virtual Eye graphics.
He said the u-Track had high degrees of accuracy and speed, and reliable live-data transmission.
It also provided other relevant information, such as wind speed, direction, vessel angle and compass headings.
Mr Taylor said that given Oracle was racing a trimaran and Alinghi a catamaran, there was much speculation on one becoming a "runaway, no-contest" winner, or the pair having a "straight-out drag race" while separated by up to 12 nautical miles, which could make television and graphics coverage difficult.
The vast sail area of the 50m masts meant dual GPS trackers had to be installed on both sides of each boat to ensure at least one was in satellite contact, because of interference from the "massive wall of carbon fibre", he said.
Oracle and Alinghi, owned respectively by billionaires Larry Ellison and Ernesto Bertarelli, have been arguing over the rules of the America's Cup in court since the Swiss syndicate won the last race, beating Emirates Team New Zealand 5-2 to retain the America's Cup in Valencia in 2007.
