Don't know the infusion, but for all boats I sailed so far:
If the nose dives (by then you did make already an error, right? But some errors are not avoidable) push the tiller *hard* to
a) turn the nose into the wind and reduce the angle of attack of the sail's
b) pull the stern down/ nose up (if you have sufficient heel angle)
In some cases you have to drop the main too.

The trick is to use sufficient rudder

Cheers,
