Abstract

In one example, a board includes a body having a single piece structure, the body including an upper surface that defines a deck, and a lower surface. The board also includes first and second retractable fins, where the first retractable fin is rotatably connected directly to the body at a first fixed location on the body such that the first retractable fin is rotatable about the first fixed location between an extended position and a retracted position, and the first retractable fin including an engagement portion that is engageable with a first portion of the body and with a second portion of the body. The first retractable fin assumes the extended position when the engagement portion is releasably retained by the first portion of the body, and the first retractable fin assumes the retracted position when the engagement portion is releasably retained by the second portion of the body.
