Due diligence... bird on post (upper left), not a seagull 20201129_171254.jpg

Yep, looked slow.

Well certainly not impressive sailing overall: off foils, bouncy ride height, looking slow. But how would the others do in such light airs? Does anyone on the scene know how the other teams do in similar winds?

Just to liven things up here's the most recent video I could find.  Luna Rosa in a good breeze and a brief glimpse of ETNZ.  


LR looking pretty damn fast and stable in that vid

does anyone realize they will have to maneuver in the pre starts... Perhaps training for such instances. Straight lines are fun and all but the boats will need to do some strange maneuvers at times

It appeared like ETNZ were almost hunting out light winds today for their testing. All the other teams have headed to areas with better breeze. And now with 13 knots they sailed back into the harbour and have dropped all the sails.

Maneuver in the pre starts? Strange maneuvers? I had no idea! I thought they just let each other pass with a hand wave and blew kisses. I am so glad you are here to inform us! Fucktard level comment there newbie.

Agreed - as noted above their speed this morning was definitely well under what the wind would have produced - it felt like they were sailing deliberately very high, or in a mode that almost felt they were using flaps to maintain stability while not climbing up...

Why would you want a body that doesn't want to fly ? you'd just have more downfoil to support on the foils .. and that'd be more drag.
It does seem counter-intuitive, but a major issue in using "full power" is in keeping the boat upright. As they have no way to substantially increase RM, such as a canting keel etc, they have to balance the boat in the transverse plane.  Balancing it in the longitudinal plane by using downforce on the stabilator is not a problem, apart from being somewhat "delicate".

That's why they often have to "depower" the rig a lot, through the use of twist - which also lowers the CE.

There is no shortage of lift from the foil, so if the hull is able to exert some downforce, that would be very beneficial to RM, so they can utilise more of the sails' forces.

I've wondered why the boats are mostly sailed bow down... perhaps to add hull downforce?

Nice on Mike.  Good to see some footage being posted again.  It looks like they might be practicing some low wind range starting manoeuvres with one of the chase boats acting a surrogate competitor.  Do you have any thoughts about what they were up to?
