Abstract
A device that enables a person positioned in a body of water to hold onto the exterior hull surface of a watercraft. A handle has a straight central part and a pair of parallel arms that are perpendicular to the central part and which extend from opposite ends of the central part in a common direction. Each of the parallel arms has a distal free end that engages a suction cup on its convex side. An O-ring is integrally formed with each suction cup on its concave side, and is positioned on the outermost peripheral edge of its associated suction cup. The O-ring increases the volumetric capacity of the suction cup and therefore increases the strength of the vacuum that holds the suction cup to the watercraft.
