When the surfer gains forward speed because of the wave, he turns 90 degree or a bit less. This means he is now gaining sideward momentum from the wave in addition to the forward momentum he already got. There is a net gain at 45 degrees (or a bit less due to friction) of relative air/ground velocity.

If the univers expansion is the wave and light propulsed by it, a ship turning 90 degrees to it could ride it faster. It’s a conjecture theory of sorts.

That's exactly how a sailboat (or sailboard) on a beam reach (wind from the side) works.
Under ideal conditions the boat can actually go faster than the wind that provides the force propelling it.

When the surfer turns, he is slowing his fall off the wave.
