Choosing a tower that is strong, self-supporting, and versatile is the first step to assembling your perfect tower setup. Regardless of whether you're looking at an OEM or aftermarket tower, it must be structurally sound and unflinchingly strong in the face of a powerful pull. Look for substantial tubing that doesn't so much as budge if you hang, swing, or otherwise jerk it around. Next, look for a self-supporting design that won't stress your deck. "You want it to be over-center, so the center of gravity is over the tower itself and it's standing on it's own," says Ben Smith, vice president of towers and accessories at Roswell, which produces towers and accessories for the likes of Centurion, Nautique, and Skiers Choice. "You want to avoid having big levers that are torqueing against themselves." Finally, look for a tower that is primed for additions and makes it easier for you to adapt to your unique boating situation. If, for example, you have to navigate under bridges or other low-hanging obstacles on the way to your waterway, you'll want to opt for a tower with weight-assisted fold-down. Pre-wired towers make it easy to add on everything from speakers to light bars.
