A device for attachment to the deck of a surfboard or paddleboard for making paddling a surfboard or paddleboard more comfortable and easier to paddle. On a surfboard the device can also assist in attaining proper speed and so that a surfer can more easily “pop-up.” The pop-up assist generally comprises a main body having a generally wedge shape attached to the deck of the surfboard generally where the lower chest or abdomen of the surfer, makes contact with the board. The pop-up assist generally creates a wedge between the body of the surfer or paddler and the deck of the surfboard, lifting the user's upper chest, neck and, head up from the deck of the board. The pop-up assist can also be collapsible, so that the obstruction of the wedge on the board is removed once the user “pops-up.”
