Saw your post about repairing stress cracks. Where were they and how big?

I just repaired 2 huge ones. Starboard side, midship, about 3' long. Port side same location about 1.5' long. I ground the gel coat down and found that the fiberglass was also splitting, delamination I guess. I ground that down till I reached solid glass. It was deep and almost had to grind through the hull! I filled with glass strips. I then went in the cabin and reinforced with glass from the inside. I hope this holds, and more inportant, no more delamination!!
