The always excellent John Navas caught Emirates Team New Zealand doing a foiling gybe, in full flight, on San Francisco Bay.
We've seen a few foiling gybes before but this is something else - in fact it was so slick we missed it, the first time. An amazing piece of sailing.
The foiling gybe clip only is below - you can see the gybe point when the jib tacks at 18secs in:
The full video of the practice session is below:
In the images below several show Oracle Team USA with both daggerboards down - they are preparing for a gybe and must lift them once it is complete. They can't sail the leg on two deployed daggerboards.
