The upcoming boat races should get interesting as the weather warms up. Notice this regatta is the domain of rich people who can afford to design and build state of the art sailboats. (Historical footnote: yes, and always has been) In Auckland NZ, people can gather in crowds and watch it live from the shore, so score one for the plebs. It looks like the crew and the helmsman really need to know their stuff, since it's all about keeping the hull out of the water as much as possible. A campaign is going to want a good crew, but this is all new stuff and the crews are still learning. Also notice, these racing yachts would be impossible not that long ago, before the age of carbon-fibre materials for one. A critical component is the hydraulic control system for the foil arms. I haven't seen this before in a sailboat.
