Gouge in bottom

[Seacraft1974]

I just purchased my old Seacraft back after 8 yrs. it appears to have a gouge from the trailer the previous owner was using. It's about 1/4" wide x 6" long. It went through the bottom and I can see the glass. I may be seeping. It's right alone the stringer. What's the best way to repair? After the summer I will have a complete redo on the entire boat so I'm looking for an easy but safe "patch" idea.
