Im 14 years old, i've been surfing for 3 years now and im now looking for something i can catch waves easily on. I was looking for a Al Merrick Waterhog preferably 7'1", good condition, and a low price. I know this is a lot to ask for but its worth it to try.
I agree that 7'1" seems big if you are looking to ride a shortboard. My 14 year old son has a 5'8" CI Pod, which has great float and paddling, but he wishes it didn't have as much float when the waves are over 3'. The float makes it difficult to duck dive so he has to ditch the board and try to swim through the white water. It's not fun getting knocked around by the waves on a board you can't control.
But if you are looking to longboard it looks like a good choice. Good with your search.
