All the teams are using hydraulics on the boats.
I'm aware of that, just as I (and SR presumably) was aware that there must be control over the trim of the foils. But it's the detail that's interesting, not just having seen a barrel of hydraulic oil next to the boat. One way of filling in the blanks is by taking information from the crew interviews.
So how do the 3 present designs use hydraulics and for what?
What control is there over foils in each case? How are they trimmed and in which planes can they be moved?
The rams under the AR wing have been shown for example but of course there is no schematic of their function, how they are activated or powered
It's always interesting that when you get into the detail, what was 'common knowledge' can turn out to have been very different understandings of the situation.
Good questions-let me know if you get any good answers....
