The term is "blow over".

Hyroplanes do it and race cars use to pretty often before areo forces were fully understood.

It looks like he needs canards or winglets near the bow, but I'm sure he is on top of that now. If he could design and build it, he surely can fix it and solve the issues as speeds increase.


Bingo.

From Paul's blog-

"Malcolm is working hard on this with input from all the team. We want to dampen the whole boat down a little and approach these speeds again from a point of safety. We will angle the foil a few degrees more so it is pulling the front planing surface down harder and stand the rig up so it is pulling up less. We had already begun moving in this direction and you can see that the leeward pod isn't flying quite as high as it had in some of the previous runs. We think that the main foil may be flexing a little more than we anticipated and that we should speculatively account for this with safety in mind. We will also look at adding 'lift-spoiling' devices on the inboard end of the beam.

From my perspective I will be a little more cautious of how aggressively I sheet in. The main flap wasn't even pulled in on the flying run. When it is it helps keep the nose down."


Race cheap, race faster, Damnit!
