New or able to repair??

So.. Thanks to some of my fellow boaters (that can't pull up to a dock) on the 4th backed into my swim platform. Put a nasty 6" crack along the back edge. If I apply pressure on it the crack does move. Does anyone know if it could be repaired or if a new platform is in my future?

Thanks!

I did some reinforcing on the back side with JB weld.

That is easily repairable. most likely any body shop could do it, or do it yourself if you are at all mechanically inclined

Yea reinforcing it from underneath for sure would not be a problem. If I'm wanting to get all the scuffs and dings, do I wet sand it and treat it just like a gel coat?
