  1. Oh, missed or forgot that. With the top-speeds conversation above, this newly-posted video (by Presti) just seemed to fit, on a slow news day. There was one video by MIH where (despite the apparent GTF limitation) they were absolutely screaming. And I think Nathan O hinted at AR having topped 50 knts in practice too. If they sort out the power nicely (replace 1or 2 guys and their weight, with a battery pack?) the new AC50’s could be seriously, seriously fast in a late October SF Bay blow.
  2. Would love to know what the top AC50 speeds were during practices, decent example here

  6. Interesting, from https://www.seahorsemagazine.com/24-content/august-2013/134-leading-edge As expected, the choice of keel pin axis incline angle has a powerful impact on yacht performance, ...
  7. Also from there, “From the prior AC boats the loads on the foils nearly doubled during maneuvers. I don't expect there is a way to create an articulating joint that can withstand that amount of force without some sort of locking mechanism for when the foils are in lifting mode. A difficult component of a lock is that the boat-lifting foil orientation is in the center of the foils' range of motion and the foil must articulate in both directions beyond this point. And the whole foil mechanism must be contained in a waterproof compartment!”
