Abstract

In one example, a watercraft includes a buoyant body in the form of a single piece structure sized and configured to support the weight of one or more users. The watercraft also includes a retractable fin connected to a pin that resides in a fixed location relative to the body, the pin including a side surface that is in contact with the body. The retractable fin is rotatable about the pin between an extended position and a retracted position, and the retractable fin includes an engagement portion that is engageable with a first portion of the body and with a second portion of the body. The retractable fin assumes the extended position when the engagement portion is releasably retained by the first portion of the body, and the retractable fin assumes the retracted position when the engagement portion is releasably retained by the second portion of the body.
