T Dock only “draws” about 2 to 4 inches of water. The minimum functional water depth is measured at the back of the Dock where drive-on takes place. Anticipate needing about 3 feet of water or deeper if manufacturer’s recommended safe operational depth for the craft exceeds 3 feet. The forward section of the T Dock can sit on the ground during low water levels! — an extraordinary feature of the T Dock system!
