Just a bit bored with living in gloomy, overcrowded, overpriced Seattle. A sailboat probably isn't practical though, some of my ideas require a 3d printer and that could be a real mess on a sailboat.
My dad lived on a 42 foot sailboat for almost a decade, his brother, wife and their cat lived on a 36 footer for around the same amount of time, it can be done. Takes some lifestyle changes though, space is very much at a premium and no matter how big the boat is you'll wish it was another foot or two. It's also an expensive hobby, however if you live on the thing and can do a lot of the work yourself, it can be pretty economical housing. A big bonus is you can untie and take your house all over, Puget Sound is a fantastic area for sailing, there are all sorts of interesting places to go. A significant downside is your house can sink, and my dad did have a close call last year when a fitting that was part of the diesel engine exhaust plumbing broke and he had taken on several inches of water by the time he looked down into the cabin and realized what was happening. Good proactive maintenance, good seamanship and having a solid understanding of your boat's systems goes a long way toward preventing a disaster though.
You could look into finding a friend near your home port and keep a 3D printer at their place. Maybe you'll find someone who is interested in shared ownership of one, or offer to take them sailing occasionally in exchange for providing a home for your printer.
