NautiCAN Hydralift skegs provide directional stability for the towed vessel without increasing total barge resistance. Hydralift skegs are so effective that it is even possible to reduce the total barge resistance. The key to this remarkable efficiency is the optimization of the skeg profile and the angle of attack to the water flow. The barge is stabilized by lateral lift, which counters the drift of the barge stern. Hydralift skegs increase towing speed and save fuel.
