They're big, slow and ugly, it's true. But when it comes to providing space, stability, comfort and family-friendliness, you can't beat a pontoon boat. You get all the amenities of home: a couch to stretch out on for a late-morning nap, a top for shade and a dinette table for eating lunch. In many cases, there's even a portable head and shower. In addition to all this, you can't beat the price; most pontoons sell for less than half the cost of a tricked-out, V-6--powered bass or walleye boat. An 18-footer, complete with a 25-horsepower outboard, can go for as little as $9,000.
