Welcome to the Diamond Surfboards website. Diamond Surfboards are hand shaped by Justin North in Oceanside, California. Visit this site to learn more about Diamond Surfboards shapes, dimensions, and how you can order a board online.

My Surfboard App, helps you to find the perfect surfboard dimensions by figuring out your target Liter Volume and then giving you the ability to enter surfboard specs to see the Liter volume of those dimensions.

I work closely with all my riders to make sure we get it right. I also personally test ride all of my new designs. From there I scale up or down to to match your dimensions and ability. And yes this includes step ups guns as well as longboards.
