No - it will cost so much money to repair properly that you could buy two or three other used boats instead. If you don't repair it properly you may well drown.
That is nonsense. Any fiberglass boat can be easily, EASILY, repaired. But I can understand why you would be frightened off. It takes some skill, as well as confidence, and more importantly gumption. If you are lacking in these, you would be better off hiring someone with these qualities.
Now let us consider cost, the other area where you are badly mistaken. First, you can find holed boats for NOTHING. So the cost to repair is your only cost. That is much less than buying two or three other used boats, which will also need work--that much is certain.
If anyone is considering repairing a damaged boat. Start with a smaller boat, and when you find out how easy or hard, depending on your point of view, you can decided to take on bigger jobs.
Let me make one more point. There are lots of boats that were not designed all the great, but you can make changes to them to make them great boats. For example, changing dead-lights to portlights, installing a spade rudder, lengthening a boat or adding a scoop transom.
So ignore the above poster. He is one of the "Can't do it people, who has to convince everyone else not to do something, simply because he can't." There is nothing you can't do, up to and including building a boat from scratch.
