From Boats to Spacecraft

I wonder if someday we’ll be able to have personal spacecraft the way that we have personal boats. I’m sure that centuries ago, nobody thought that people would have personal motorized boats like the ones that are so commonplace now, even if perhaps people back then had their own sailboats or canoes or whatever. I’m not saying this is something that will happen in my lifetime, but I’m talking centuries from now. Will people go out and buy their own spaceships?

What I wonder is if the same companies that make boats will transition over to making spacecraft someday, or if it will be car companies, or perhaps new companies entirely. And I wonder if the companies that make the maintenance supplies for boats and whatnot will be the same ones making the oil and other things for your spaceship. That’d give Mercury oil a whole other meaning.
