I would call that an "OOPS", or not too much of a big deal. Since you've already decided to fill those areas that didn't quite make it, there are two things you need to do:
- fill those areas with either straight epoxy or epoxy mixed with silica fibers, West Systems 406 is what I use in areas like what you showed in your picture
- sand the filled areas flush with the adjacent sides/bottom after it has several days to cure. BE SURE TO KEEP THE EDGES SHARP OR THE WATER WILL SUCK THE BOAT DOWN!!!!!!!!!!!!!!!!!!!!!!!
Just remember, when you put a coat of primer on it no one will see or know it's not perfect
