windy here too.....

that sounds so frustrating.   i have boats with colored hulls....and they get scratched....so i understand the problem.  here are the approaches i use:

quick repair/small tighly grouped scratches:  sand/fill the scratch, ensure a clean surface (per paint can instructions) and using a foam brush paint over the scratch and with a dry part of the foam brush, feather it into the remaining paint.  work when it is cool so the paint is not immediately setting up.... step back several paces and bright sunlight and it will disappear.   will be viewable upon close inspection....but that's typically not how somebody will look at it.

larger repair (long scratch or an injury to a single panel). sand, clean and repaint that individual panel.  use the break between panel (facets) to hide the repair.  for this kind of work i will use blue tape to protect, ensure i don't accidently start work on a panel that i don't want to work on.  if it is a side panel, may need to remove foot braces to properly paint behind the bolts....its hard to paint around....but you can do that too with some blue tape to mask it.

reconditioning:  this is basicially refurbishing the boat.   most of my colored hulls....will do this once every 6 to 8 years.  all the painted surfaces are sanded and cleaned and the hull is repainted.

sound like, for you i would choose one of the first two.

It isn't a Tradgety. It is an opportunity. You've had damage. You're gonna fix it. Now you are ready for rocky beaches, boat ramps, docks, etc. Get the grief over early is my normal recomendation.
