Nice boat.
Yeah, if you are trimmed up too far it will "let go". Your pics are actually quite a good help with the explanation - as you turn, the boat heels. Ribs even better at this vgame as you have a sponson to give you a bit more "lift assist" in a tuirn. Net result - the prop is lifted slightly closer to the surface..... Does it let go occasionally in big waves too?
I assume that engine is power trim - just trim in slightly if you are planning on turning a lot. May knock a touch of your top speed, but if you are turning a lot, top speed becomes a bit irrelevant anyway.
if it's a manual tilt, you need to make a decision about whether you prefer turning or straight line efficiency........
