I'm no expert, but I would think that the hull looks repairable to me. You might have to cut in a access port or two so you can lay up some glass from the inside, but that's no big deal. I would try to dissamble the boat so you can work on it upside down, to lay in the interior repairs. It might not be pretty when it's done, but I would bet that you'll be sailing it again.
