So I'm a newbie at surfing and I'm trying to move to bigger waves...like 3-5 ft, and these waves break pretty fast. The problem I have is that when I drop into a wave the actual drop is higher and steeper than before and the tip of my board drops down and goes in the water and pretty much wipes me out. I tried standing up faster and kinda pushing down the back of my board but I still have the same problem. I have a 6' 9'' shortboard (well its not really short) and the tip is even raised a bit. But once the tip goes a few inches under water the whole board flips foward.
What am I doing wrong?
