Pictures would help to see the extend of your damage and a possible solution. Is it just the gelcoat that is scraped up, or do you think you have some fiberglass (structural) damage as well?
If this is an area that is easily visible and you want a repair that won't be noticeable, you will probably have to take it in and get it repared. Otherwise, I know they make an auto body type filler that is fiberglass based. I think I have some at home and it is called Duraglass. It works just like the auto body fillers. If the damage is not too bad, you might get away with using Marine Tex.
Again, pics. would help us see what you are up against.
