Hi all,
When a ship has 2 screws, one turns left and the other turns right. When I look at the different forces on the screw-blades, every force that is not in the axial direction has a counterforce. This leafs only 1 force, being backwards so that the boat is moved forwards. (make any sense??).
Why will a boat with only 1 screw drift a little. When a boat has 2 screws, one turns left and the other turns right, why is this??
Thank you in advance.
