Hi Everyone,
I accidentally dropped my friend's older board the other day and now it has a hole in it

After I finished swearing at myself, I took a picture and now I need to figure out the best way to fix it.
He hasn't sailed it in 6 years, so I don't need a fix for optimal performance. I just need the best way to patch up the hole. Can I epoxy it?
It looks bigger than it is in the picture. The crossbar on the "T" is about 1.9 cm and the long part of the "T" is about 2.5 cm. The hole is on the side of the board, right in the crease there. Am I totally screwed?
Any tips would be greatly appreciated.
