Yes, I think you're on the right track. The AUS team is known to be quite aggressive in pushing their boat to the limit in stronger winds, but we could see GBR with a slightly higher speed than even the Aussies. So losing the starboard rudder foil was most likely the primary cause for the loss...
There is a very complex relationship and balancing act between the forces acting on the F50. Basically, the main foil provides lift, and the windward rudder foil is providing down force to increase righting moment. In those high wind conditions, that rudder foil is adding around one tonne or...
29.4m wing, that's not much under 100' - big bugger. Interesting that the jib is contributing 15-20% to power, but I'd assume part of that is the amount they complement the wing.
No doubt you're right, I've only been around here less than a year.
When I began participating in this forum, I made myself 3 rules:
Rule 1. Don't join in on arguments
Rule 2. Don't down vote other posters
Rule 3. Don't put other posters on the 'Ignore' list.
I've only broken Rule 3...
Given the "Abbreviated Rules" linked at the top of the page, this probably won't happen again. Fair enough, it's their forum, so 'It is what it is.' :rolleyes:
Note that SailGP started with a 4 segment (all-purpose) 24m wing, then removed a segment which became the 3 segment (strong wind) 18m wing.
The 24m wing is now a "moderate wind" wing, as they have been testing a new "light wind" 5 segment wing, but I gather they were not yet production-ready...
Allow umpires to exercise "leeway" with the Rules, and I think you'd open Pandora's Box.
I've seen BA in races from years past; if positions had been reversed, I very much doubt he'd knock back that opportunity to force a penalty if he could.
These are complex questions! To the best of my limited ability:
Foils. Due to their shape, they provide both vertical lift, and lateral lift (like a keel). To minimise drag, the teams try to fly the F50s as high as they can without causing the foil to ventilate, thus stalling the foil. ...
I'm not quite sure what you mean by "point of lateral resistance"? If that is resistance to leeway, it's mainly a function of the foil.
Being roughly "L" shaped, the vertical component of the foil provides most of the lift to windward, thus reducing leeway.
To a minor degree, the rudders also...
