Hello out there, Odysea fans and internet dwellers alike. We, at Odysea, after many cups of coffee (and the nervous twitching that follows) decided that we wanted to create a blog series for the beginning and uninformed surfer.

In today’s “blogisode” we wanted to talk about what makes a surfboard i.e. the core of the board.

When you go to purchase a surfboard at your favorite local surf shop, there are two different core materials they are made of. First, and most commonly used, is Poly-urethane, or PU. The second,  Expanded Polystyrene or EPS. The best way to describe the differences is: PU is a tightly packed, dense foam, with very little air. EPS, is like stryofoam, the only difference being it is a little stronger. See photos below.

                                                                      PU Blank

                                             EPS Blank (Note the styrofoam like consistency)

Both photos above feature the blank, one untouched and the other in the beginning stages of shaping. A blank is the building block of any surfboard. It’s where it starts, and for the most part, where all the magic happens.  From the blank a shaper  can create a surfboard using a myriad of tools like, a planer and a sureform. At this point of making a surfboard the  shaper can add rocker, concave, decide what kind of tail, etc. (more on this in the next post). After the shaper thinks their vision ready for lamination, the blank goes from the pictures above to something a little more recognizable.

Join us for the next “blogisode”: “They do what with that?!” We’ll go over the next process after the blank is finished: Lamination and we’ll also cover rocker, and concave. Catch you next time.
