I wonder if they've got bladders full of helium in the hulls. I thought back when Larry won the cup on the big Tri, someone said they had some helium in the amas to lighten it up?

Aero beams are primarily for drag reduction. They are trying to re-attach the flow aft of the tramp and keep it attached forward of the tramp. Attached flow is much less drag than fully detached flow (i.e the wake coming off a round or square beam).
Remember the prototypes on hull #1? They didn't build them there for a reason; CFD is good but modelling separated flow effectively is more of a rare art form than a science at this point. Much easier to instrument your system in a wind tunnel, i.e put tell tales all over your ribbed beam and design the solid beam from there.
Gonna be a fun summer with the AC and C-class action...

The blurb released with the trailer describes it as:
'Awe-inspiring boats that reflect the unlimited reach of human ingenuity, breathtaking views, action, tension, excitement, consummate skill, the pursuit of lifelong dreams and the tempestuous romance between sailors and the sea, set against a soaring musical score: this is The Wind God's, the story of the 33rd America's Cup race.
'In a quest to bring the oldest trophy in International Sports back to America, Oracle Corporation's Larry Ellison organizes an elite team to sail USA-17, the most technologically advanced sailboat ever built, in a challenge against the defending Swiss team Alinghi, which has held the cup for seven years.
'The film documents the effort from start to finish, with intimate portraits of the competitors, fascinating insights into the cup's history, and sweeping cinematography of the race. But more than that, The Wind Gods is a tribute to the adventurous spirit that leads men to test their limits, by challenging the elements, the sea, and fate.
