AC 72's.
The first year they have raced something this big with that big of a mast. Prior to than it was AC 45's.
Everything is carbon fiber, titanium, and or Kevlar composite materials.
Super light weight, insanely strong and, it just flies.
Like Formula 1 on the water.
We helped with the event since we are next to SF and hosted one of the teams one day for a social in our area during the AC Cup race in 2012.
The tech's told us during testing, these larger boats (Fully extended the mast is almost 13 stories tall), they could hit somewhere between 40-50 knots in certain sections of the course, and maybe more depending on the weather and current.
That is hauling butt.....
