Step-up or Semi-gun rounded pin Thruster, but can be a Quad option board. Rocker is smooth and moderate with slight single to double concave and low soft rail. DSCV is a similar design but has vee in the back half of the board.
DSC has been around since 1994, slowly evolving as a dependable all purpose good wave board. DSCV was introduced as a bigger board semi gun option.
Designed to have speed and life, but balanced with control. In bigger surf DSC sets up the wave from the first bottom turn holding a pure line with no stutter or drift, a critically important element in timing your next move higher on the wave face, or setting up the next section for a possible barrel. Usually surfed an inch or two longer and similar width and thickness as your normal all-round short board. DSCV was developed to make a bigger board in a gun shape more user friendly. The vee makes it easier to go rail to rail and carve a shorter arc on a longer rail line.
