I did a similar thing with the rudder on my M-15 nearly 20 years ago. I went to a store, bought a fiberglas patch kit, repaired the rudder with the kit, and am still sailing the M-15 with the same rudder, I think it may even be stronger than the original before the patch.

I ran my M-15 aground on a sandy bottom, which would have been no problem, however as the rudder kicked up I turned it unknowingly into the prop of my engine. I took about an inch off the trailing edge of my rudder that I will now have to fix. I don't know if this has happened to anyone else or if it has been posted before but I wanted to make you aware that this can happen.
