Developed by Seaspan Development Co. Ltd. of British Columbia, the new skeg design for towed barges results in a 10 to 15% higher speed for 20 to 30% reduction in power required to tow loaded barges at the same speed. The hydralift skegs consist of a number of vertical foils fitted to the barge at each side of the stern rake with horizontal foils connecting the bottom tips of each set of vertical foils. A lift is induced by the airfoil shape of the skegs to establish stability while at the same time producing a forward component of lift, thereby reducing drag. Order from BSRA as No. 49,258.
