They've been showing video clips of what happened when OTUSA-1 hit a buoy. Its amazing to see the difference between ETNZ and OTUSA stopping dead from being up on foils.
Oracle looked a lot less dramatic than ETNZ even with a chain hitting their foils.
I can't find the videos of them hitting the bouy. Can someone link it here? I'm getting spoiled by this one-stop shopping for all that is AC.
