Proton Step-Up

Model Description

The Proton Step-Up is now the most common step-up in use with the CI team. With its pronounced rocker, it is a natural choice for steep faces and on-rail surfing. Single concave gives the board plenty of drive for critical situations.

    I need your advice of which board to buy for a second step up board for waves size of overhead to double overhead.

    I have already a Fred Rubble 5’9 x 18 5/8 x 2 3/16 round and I am looking for a second board for bigger waves , overhead to double overhead.

    My weight is 155 and I am an expert level surfer. So which board and specific measurements would you recommend?

    Thanks,
    Best,
    PJ

      PJ,

      The Proton at somewhere between 5’11 to 6’2″ at 18 5/8 x 2 3/16.
      Or an SemiPro12 a the same length and width but at 2 1/4.
      Both would need to be custom and with a round pin.

    I have the same question as PJ, as to what dimensions you would reccomend for either a Proton or SemiPro step up. I whiegh about 180 and i am an advanced surfer. My current every day board is 6’0 by 18 and 1/2 and 2.25 thick.

    Thanks guys,

    Joe

      Joe,

      You must be in some good waves as that is a low volume Proton for 180.
      If you are likeing that Proton, just blow up the length 3″ to 6″ depending on the size waves you are looking at.
