The instant invention provides a docking device for a boat, which may include a pair of docking elements. Each docking element includes a vessel contacting element or wheel that may be retained between an upper wheel holder and a lower wheel holder. A spring element may be made any suitable material that is resistant to ultraviolet (UV) radiation, waterproof and salt-resistant. The spring element includes a first leg, which may be fastened to a sidewall of the dock and a second leg. The spring element may be straight or may include an angled portion. A wheel may be rotatably attached to the spring element by an upper wheel holder and a lower wheel holder. A first edge of the spring element may be received within a slot in the upper wheel holder, and second edge of the spring element may be received within a slot in the lower wheel holder. An angled spring element may be used, when the width of the boat does not closely match the width of the dock area. To compensate for a large discrepancy between the width of the boat and the docking area, an included angle up to 90 DEG may be utilized. An alternative embodiment of the docking device may include a pivot base having a plurality of bosses with angled faces and a pivot arm for carrying a wheel that contacts a boat. A spring may bias the pivot arm away from the pivot base.
