Hi tried this for the first time today.
One thing I notice is that it's difficult scull such that the force is propelling you forward. It's like you can scull but the force alternates between outward then inward.
Is this correct? Or should you be trying as best you can to to scull and feel the water in order to move forward effectively?

Take attention to the position of the hands, they change between two positions inwards and outwards
