Boat is overpowered in a gust:

Spinnaker flogging, boom dragging in the water and cannot be eased
further.

In the pic, the boat is still moving forward but very soon the foils
will stall and she will be uncontrollable. The skipper has a few
seconds to take action or they will capsize. What should he do?

As a bonus question, what is different about the boat in the pic from
most conventional sloops that might affect the skipper's range of
successful options?

Do the opposite of what seems obvious, head down, get under the main,
jybe.
