I see that. Frame is bent. That is going to give the boat a unique sonar signature from now on.

Could one assume that every boat has a unique sonar sig, and that slight bulge changes its sig, or does it make it worse?

I would think that having a bent frame in the middle there is not at all desirable but given its location, makes it even more of a *itch to fix.
