I went to the York River again for the last practice derby entry before the NCC. Since I damaged one of my amas and I feared I could not do an adequate repair before the big race, I borrowed some amas from the dealer (Peter) in Florida. These amas were previously damages and repaired and I like the repair job. As the video shows, a large piece of twill weave fabric (wither fiberglass or carbon) was placed as a cap over the whole wing connection area (and farther) to really distribute the forces from the ama. I plan on doing something like this to repair my own amas after the NCC race.

The day testing them out was a fairly light wind day but they at least remained water-tight.
