Half Towers for boats are most commonly reffered to as Hard Tops unless the top is made with sunbrella canvas.  Half towers are designed to give the captain a weather resistant drive while also providing shade on sunny days.  High Speed Welding Half Towers can either be made with a fiberglass top for mounting lights and radars or with a sunbrella canvas.  Our Hard Tops are fabricated with various sized pipe depending on the size of the boat and tower.
