A boat tower, comprising a support frame comprising a first leg having an upper end and a lower end attachable to a first side of a boat, a second leg having an upper end and a lower end attachable to a second side of the boat, and a cross member extending from the upper end of the first leg to the upper end of the second leg; and a vibration dampening apparatus having a first end, a second end, and a longitudinal axis extending from the first end to the second end, and connected to the support frame in a substantially perpendicular relationship to a vertical plane which laterally bisects the cross member between the first leg and the second leg in a way that the vibration dampening apparatus mitigates lateral vibrations of the tower when the first and second legs are attached to the boat.
