Are propellors on twin screw vessels 'handed' in the same way as the propellors were handed on the DH Hornet and P38, or do they both go the same way?
If you've got any sense yes, there's a sideways force* produced by them which is useful when manoeuvring at low speed. Obviously if they're handed you can generate a force in either direction.
*Often called the paddle wheel effect, although it's a bit more complicated than that.
