My garage is 48' deep. Just right for my 32' with a little room to spare on the ends. Takes the full 8' tall door to get'r in, so I am limited to the size and make of the boat just do to the door height. A couple buddies have a 34PQ and 35 Cig, they need 9' doors to enter. The door height will be your biggest obsticle for an attached garage.
