Stuck at an invisible wall in water hazard

[zzornn]

I can't seem to get my air boat across the gap at the area where the two rocket launcher trucks were above me. I can jump the gap but my air boat seems to smash into something. I can run through it but I need the airboat for the helecopter in the next section.
Did anyone else have this problem?
I don't want to use a cheat to get through.
Thanks,
Zzornn

Just load up an earlier savepoint and blow up the cars again.. should help. Not that your problem happened to me
