The effects of twin screw propellers are not so complicated as those of single screw. It is only necessary to take into account (1st) the current caused by the screw and to consider whether it is a discharge current acting against the fore side of the rudder or whether it is a suction current drawn in against its after-side: (2nd) the transverse thrust of the screws; (3rd) the athwartships distance between the propellers which results in a couple being set up when going ahead on one engine and astern on the other.
