The worst broaching boat I’ve ever been on was a poorly trimmed Blackman Billfisher. That thing would go from 25kt to zero with a 90 deg turn thrown in. And this was in a 3’ 15 second ground swell going downhill. Bayrunners are known to bow steer. You learn to feel it coming and back off the throttle. I know someone who broached his somewhere in the Gulf of Calif. He went from going just fine to a complete stop, boat upside down, and swimming in like 2 seconds. Radons/Davises: I don’t think it’s possible to broach those things. Amazing what you can do in those hulls.
