Bar from the hang to overhead in one violent pull, caught high.
Keep the bar close and brushing your hips, punch up hard to lock it overhead.
The hang power snatch is built on a violent hip hinge: the hamstrings load hard as you push back to the hang, then snap the hips through with the glutes to send the bar overhead in one pull. Catching in a quarter squat rather than a deep one means the hip drive has to supply all the height, so every rep trains raw posterior-chain speed. It earns its place with athletes who want snatch explosiveness and overhead confidence without the mobility bill of a full squat snatch.
The power version catches high in a quarter squat and trains pure pulling speed with lighter loads. The full hang snatch catches in a deep overhead squat and demands far more mobility. Most lifters start with the power version and it stays useful forever.
You are bumping it forward with your hips instead of brushing it. The bar should skim up your thighs and stay over your feet. Think vertical hips through extension and keep the bar close enough to feel it.
Wide enough that the bar sits in your hip crease when you stand tall with straight arms. That is your reference. Too narrow and the bar hangs at mid-thigh, forcing a longer, weaker pull to get it overhead.
