Your question is almost unanswerable, because of the many types of boats out there. Wood, fiberglass, aluminum, inboard, outboard, open, closed, etc, etc, etc.
On the cheap and easy end is the simple aluminum skiff with a little portable outboard. It has no maintenance. Flashlight up front, little outboard plunked on the rear, and away you go. Small ones can be carried well by two people, and fit into the back of pickup trucks. These boats sit abandoned in the back yard for years, and work perfectly when picked up and tossed into the water.
Wooden boats, you don't have enough money for one. I do love them myself, but they take maintenance, lots of it. For wood rots, enthusiastically. And if it's not rotting, it's shrinking. Then the boat leaks when placed in the water.
Fiberglass sounds great, but there's usually wood behind it, rotting with enthusiasm. That boat you linked, I bet it has a rotten transom. Put in inboard motor in there, and they really rot. For what better idea than to cut a hole in a fiberglass panel and let water into it edgewise.
If it's got wires, and that linked one does, they fail with remarkable speed on boats. A fuse, a switch, the wires themselves, it just doesn't matter. The same switch that works for 15 years on your car will die in 8 months on a boat.
So if you're still with me at this point, talk some more about what you think you want to do with a boat. Then you will get better more specific responses.
