stringer problem

I used to own one of those cheaper boats that was also a bass boat I was using it to fish our bay's down here in galveston anyway's the boat was slightly overpowered and after launching it off of a tug wake the landing split the hull in 5 places on both of the chines immediatly started to leak bad had to beach it and pump it out several times to get to the boat ramp. The moral of the story is if the hull integrity has been effected from my experience you would know it. I've seen gel coat cracks on some real good boats that only effected boats looks not stucture.
