Still no luck I'm afraid.
The double tap centre thing is a neat trick to know, but I don't yet need it for the rudder, because even if I turn it all the way to the right the boat still doesn't turn enough to follow the blue line. In fact, after the initial slight turn which is initiated by the game, it seems to me like I lose control altogether. I can still set speed, but no amount of turning the rudder seems to make the boat turn in any direction.
I used two fingers to zoom in and out, but only one to manipulate controls.
