The foil is part of the daggerboard.
In the below attachments--taken from the video--it forms an "L" shape, which is tucked against the hull when retracted...

...and forms "V" shape when immersed--a sailing foil
shape learned from sailboat designs dating from the 1950s--perhaps earlier. Note the outboard
and inboard spray from the "V" in the first photo.
Since the top of the "foil-board" is still exposed to drag, I think it is retracted to avoid "tripping-up" the boat when the hull returns close to steep waves at high speeds.
