thats a major structural repair......that needs a big footprint from both sides of the hull....at least a 12:1 ratio scarf each side, if not more....go as for as you can on the tapered scarf in all directions.....the layering depends on the original thickness....you want to make it the same thickness........I would use multiple layers of either 12oz or 17 oz 0/90 biaxial glass without matt......and use epoxy for the best secondary bond strength......scarf from the inside first and build the thickness back to original....then do the outside and build it back to the same original thickness or slightly under by a few thousands to allow for fairing....then fair and paint or gelcoat...
