To come closer to the entertainment system you might have at home, there's no substitute for a dedicated screen. As you may have seen during the run-up and aftermath of the holiday shopping season last year, the prices have never been lower, and you no longer have to settle for a small screen. Samsung, Sony, Phillips, Sharp, and many, many other manufacturers offer a wide range of screen sizes, and while a 42-inch screen may be overkill, a 20- to 32-inch screen works fine in most saloons, and they aren't that hard to install, whether or not you're a professional. Of course, having a pro do it might save you a lot of time and effort in the long run, considering how complex a boat's system can be these days. "It's just like installing entertainment systems in a house," says Jeremy Rudman, a systems installer for Flint Mobile Marine, in Middletown, Rhode Island. "But you definitely have to plan it better. We like to get a set of plans from the boat's builder or designer and talk to the customer before we install a full system."
