Not sure I can tell exactly where your leak is from the photos, but I would recommend a weld if you have access or JB Weld (an easy epoxy) if you don't. The JB Weld might be the easiest option anyway. I have used on boats and my automotive engines many times.

Specifically, marine grade epoxy.
JB MarineWeld or construction adhesive.
This is not the technically correct fix, but I've used J-B Weld on my 1993 fiberglass boat that had similar damage. It's not a pretty fix, though it would look better on your grey boat than my white one. It's a marine epoxy that I mixed up and "patched" the area. If it's on the bottom of the boat no one is going to see it anyways. It's 20 years old - it's not worth doing the proper repair. I'm on my second season and it looks the same as the day I did the patch.
My boat came with the damage and the previous owner drove it without it spreading as /u/LikesGladiatorMovies suggested. I wouldn't guaranty yours will hold up the same but that is my experience.
JB Weld is pretty much the epoxy to go with for nearly everything, they have a marine version:

I used to work in boats and there are only a few products that really work. They vary in price and are for different applications.
For smaller patches JB Weld has a two part marine adhesive that isn't too expensive (make sure to follow directions)

3M has a tape that i've used before and works well if you can dry/clean the surface before applying.

On a similar note, probably also not the technically correct repair, But 4 years ago I repaired several 1 inch sized dings through the gel coat on my keel with JB WaterWeld. Before applying I cleaned it the area well with rubbing alcohol and a toothbrush and then dried it with a hair dryer. The boat is white so it was a good match, and with just a little sanding it looked pretty darn good. Four years later those repairs are still holding strong. Good luck with your repairs OP. It should be an easy fix, just be sure to take care of right away before it gets worse.
Edit: Marine Weld might be a better match for you since it will dry a dark grey like your hull. I prefer to work with the putty that I linked above because it is easier to shape. But I bet the marine weld would do a good job for you too.
