Okay... now to the nitty gritty.
Getting out past the surf:
First thing's first. When paddling out timing is everything. Typically, waves come in sets; get out between sets. If a wave has already crashed and a foam pile is coming, you MUST get the nose above the foam-pile. Rock the bow up just before the foam pile hits, then as soon as the nose is above the pile, immediately lean forward and paddle like hell. This will bring you to the top of the foam pile, keeping you from getting stuck in a backward-surf. So to recap; clear the nose, then lean forward and paddle like hell.
Catching waves:
Okay so one quick thing about catching a wave; as the wave comes under you, paddle hard and put your boat on edge so the hull cuts into the wave. You will be able to catch waves more easily as you are putting your boat on a track. You should also be heading slightly right or left on the wave. Very important, don't look straight ahead as you surf the wave. Turn your head so you can see where you are on the wave, and then pick a spot where you want to go. Spot your target, lead with your head, and go to it. Be decisive and look at where you want to be. Especially with longer boats, it helps to cut one way or the other to prevent the nose from diving. This helps pull you higher on the wave and prevents the nose from diving under.
Quick Tip:
When trying to turn on a wave use a combination of forward sweep strokes and stern rudders on the opposite side. If you only rudder you will not have the momentum to carry you into the next turn (kind of like planting your pole when you ski).
Last but not least:
If you capsize and you miss your first roll, wait a few second for the water to settle down a bit before you try again. It can be a bit difficult to roll in a foam pile because the water is turbulent in many directions and the water is filled with air, making it less dense and therefore harder to catch tension with the paddle. Feel free to ask more questions if you have any. I hope this helps, let me know how you do.
