Crack in a Boston Whaler?

I have a 1960's 13' Boston Whaler and upon flipping it, because it's so old, the weight of the boat made a crack from the rub rail, all the way to just before the hull. I would like to know how to fix this. Should i just grind out along the crack, plug it with fibers and cover it with cloth? Thank you.Crack in a Boston Whaler?
