What Boats will fit in a standard garage?

I currently own a Supra santera so it would stay at the place I store it over the winter for now. But for future ideas I was wondering what boats might fit. The house we are looking at buying has a three car garage, a double bay and an extra long single bay. Single bay would work great even for the current boat as it is 25' long but the door is only 95" so it is out.

Double bay is only 20"5" deep. Yup I know that is damn shallow and things would be real tight. I am not against building a box in the back wall to squeeze and extra few inches for things like a wedge or taps. I would have to back the boat straight in as I would still need to use the other spot for parking. I know it's possible to do it with something like a Tige 20V but I was wanting to look at all the options.

So if any body has experience with making a boat fit in a small garage please chime in I would love to here about it. Yes I know it would be a pain in the but and this isn't something I will def do I just want to see what people have to say.
