Crack in acrylic bath tub, but fiberglass is ok

I managed put a small crack in the corner of my acrylic bathtub. Looking underneath it looks like the crack is just to the acrylic, and the fiberglass shell is still in-tact.

Is this enough to hold water? Looking online, the fiberglass does the heavy lifting – but didn't want it to start leaking! I'll repair the cracked acrylic at a later point.
