I thought the idea was to keep the keel vertical????? surely it's more efficient that way.
The idea is to maximise the advantage of the weight bulb on the end of the keel. They wouldn't normally sail heeled right over on their ear like in video, though and they wouldn't normally cant the keel until it clears the water surface. That clip is done for an ad, not for maximum performance.
A couple of boats have been released where the canting keel is designed to fly just above the water line to reduce drag. Makes for interesting racing in thight situations.
Ill also add that its not 100% sucesfull yet as under spinikar is Sydney Harbour the bulb fell off
