You can do a quick patch job or take the time to do a real repair. If its just the gel coat(tinted resin), easy fix with a gel coat repair kit that has multiple colors to get the shade just right. 80, 120, 320 grit sandpaper, acetone.
If the damage is a little deeper, looks like it is(fiber strands are white and stressed, no longer bound in resin) same as above for finishing but you'll need to grind out the damage and flair out from the center. Quarter size damage could go to 2" or even 6" or more depending. flapper wheel on a grinder works great, 5 bucks at HF.
After grinding and cleaning, the depression needs to be built back up in layers with fiberglass and resin. cut small circle of fiberglass cloth the progressively larger for each additional layer until its just above level the sand flush.
Sounds harder than it is. I did an entire boat with no previous experience. Mine suffered from an owner that had a drill and a saws all.
