Also if you are looking for a webcam covering the harbour: My camera at https://oceanswims.nz/webcam updates every minute - click the photo to view it full size.

Could the “definitely not a camera” be looking at the intersection of the bulb/foil when it is immersed to see at what point there is flow separation and how it interacts with flap movement?There are registration lines on the underside of the foil(s) so something must be watching those

I only caught the last 15mins of their session today, wasn't paying attention out the window.
Closest approach to me at about 10 mins in
That would be a reasonable study in a real test tank. Do you reckon you could see that viewing along a meter of wing? I've just seen tank footage from directly above in clear water. Although with the lack of rain the sea is pretty clear these days. Honest question for someone who has played with tanks.Could the “definitely not a camera” be looking at the intersection of the bulb/foil when it is immersed to see at what point there is flow separation and how it interacts with flap movement?
Mine was an honest question from someone with no idea as never played with tanks. No clue if it’s practical/feasible but worth a guess?That would be a reasonable study in a real test tank.

That was my thought, the place to monitor the entire wing was from above, just where we saw the camera bulb on te aihe. Like you said, ventilation showed up from drones.but maybe some cavitation on the bottom surface that needs a look.Mine was an honest question from someone with no idea as never played with tanks.

actually some of the drone heli shot of ineos when it first launched you could see flow/attaching detaching as the foil got close to the surface do maybe they can get something meaningful from underwater?
still, TC says they ain’t cameras so fuck it who knows! Lol
Certainly supernatural, that's for sure. ;-)Fucking voodoo boats anyway.
I posted some time ago an anecdote of a discussion with AMac circa 2015 (no idea how to find it) so I'll restate it. AMac's done his fair share of foil development and reckons bulbs are faster. Apparently he challenged some AC types with their zillion dollar design and analysis packages to design a foil without a bulb that was faster than the same foil with a bulb. They couldn't do it. Asked why the bulb is faster, he just shrugged.I just spent over 2 hours trying to find our discussion on foils where NZ was the outlier and all the other teams went with the bulb. It must have been in the "old NZ" thread that was deleted. I said that I thought NZ would eventually change over to the bulb foils. The idea was that all of the other teams had already tested the bulb-less foils on their test boats and all of them decided independently to change to the bulb foils. And all of the bulbs had the anhedral foils where as NZ started with one T-foils just like AM did on the Mule. Most of the NZ posters said that I was missing the brilliant design of the NZ foils, I said that NZ was playing catch-up because they didn't have the "on the water" test boat experience of the other teams.

Check the (barely visible) logo on the sail. Not flipped, unless someone took the time out to un–flip the logo.Interesting to see the bulb now on the port side foil, earlier pictures showed it only on the starboard side. Either they switched sides, put bulbs on both foils or just flipped the picture.
The entire foil (which is everything attached to the bottom of the arm) has to fit in the box defined in fig. 13.1 (reproduced below), the appendage on the tip seems to go well outside the box.Can you quote [the rule about stuff on the tip] please?
We’ve seen ‘bulblets’ along other test foil-wings, and there’s been guesses that they house controls for the trailing flaps aligned with them. Might not these be controllable surfaces too, if that wing-tip part is ‘trailing’ as the other flaperons are?

Fuck off troll.You mean like the words circled in bright red in @RobG's post preceding yours by over 15 mins?
Cat or Parrot?
