Re: New board help :)
There are just a few differences between the two, but the important thing is that a longboard is more forgiving of your mistakes, a shortboard isn't
With a shortboard, and I mean just when paddling around, you have to be exactly where you can make the board the flattest, too far back you will push water and not go anywhere when you paddle and the wave goes right under, too far forward you pearl. You know when you are perfrect as you paddle, if you are too far back you go nowhere, too far forward it starts to sink the nose. Get used to having it plane on top of the water.
To paddle a shorboard more effectively hold your head high, arch your back, this does two things: First, you will paddle down,not out, scooping water back, using your arms, shoulders and lats to paddle. Second, when you are catching the wave it will counteract the pearling effect, keeping you on the wave curl.
Lastly, go back to my prior post and practice your popups, no use getting in the lineup if you can't stand on your feet. Wait for a nice strong whitewash, throw yourself forward and on top of the board as opposed to just flopping on the board, then pop up, right away, even if you don't surf. You are practicing popups, not surfing. All begginers start this way, it's just easier on a longboard because they don't sink LOL
