Beginner = shorter board = easier to turn
When you advance a bit, you'll notice at higher speeds that the board you're riding begins to lack stability. You'll know immediately as you'll feel it chatter under your feet.
At that point, you'll want to hop on something a bit stiffer/longer so that you can keep crushing it.
