approximately twice the mean chord of the skeg elements as shown in fig4 while two skeg elements could be used in each set or more than three could be used it is preferred that there be three skeg elements in each set if there are more than three the aspect ratio of the skeg elements should be increased by reducing the mean chord of each element consequently adjacent skeg elements could be located closer together but they should not be closer than 11 2 times the mean chord to provide the best yaw deterring performance and the greatest reduction in drag also the two outboard skeg elements of the sets are located closer to the respectively adjacent sides of the barge than one half of the spacing between each outboard skeg and the next inboard skeg of the set as shown in fig4 the individual cantilever dagger skegs shown in fig1 to 4 inclusive are somewhat vulnerable to being struck by floating objects over which the barge b may be towed the skegs can be unified and strengthened by connecting the lower portions of the skegs in each set at opposite sides of the longitudinal center line with an elongated bridging member.
