The first part of the railcart tracks at the shipyard were fine. I am at the second part now and there is a section of the tracks that are broken. I have tried to jump the cart at the right time but always fall short. I have also picked up some speed but it is never enough to make it over the gap. How are you meant to ramp over to the other side of the rollercoaster part in the desert?
It is all about speed. When you are turning a corner, if you counter the turn with your body you will get a speed boost. The better you counter your weight the better the boost.
Just before the jump in the tracks, you will get a few bends that you must nail down in order to gain enough speed to make the jump across to the other side.
