I watched a show were they made a repair like this. They started by taking a peice of carboard and rubbing it with wax on the side facing the hole. Then they taped it to the bottom of the baot over the hole forming it to the boat. They then did the glass layers to the inside and after it set they removed the cardboard and sanded. Did the outside layers sanded and it was good to go. The guy said he used the card board as backing so he could work the glass over the hole area.
