Gel Coat issue

[Sdfish]

Hi guys - I've had these gel coat cracks or lines in my boat since I purchased it used a few years ago. Is this just cosmetic? I'm thinking it was a trailer hit.
I can dremel out and fix the cosmetic stuff, just want thoughts on if this is more than that.
Thanks!

Looks more like banging into the dock to me. Maybe when docking. Right height for floating dock.

I have some cracking up on the gunnel, smaller localized cracks, from laying the boat on the dolphins. Wind gets a hold of my bow and slams me over. Sounds awful when it happens. No more after my bow thruster was installed.
