ABSTRACT:
A device for example for securing a boat to a dock having spaced boards. The device comprises a body having a shaft and an elongated head secured transversely to one end thereof. A plate is mounted on the shaft for slidable movement thereon towards and away from the head with its plane parallel to the head, to provide an adjustable but uniform space between corresponding points on confronting surfaces of the head and the plate. These surfaces, during operation of the device act to grip therebetween planking of the dock. A spring is associated with the shaft and plate to urge the plate towards the head as this space is increased from a minimum value. The device further comprises a ring to which a line from the boat may be secured. This device greatly facilitates mooring a boat or the like to a dock or similar anchor structure in that the device, to which a line from the boat has been attached, need merely have its head passed longitudinally between adjacent, spaced boards of the dock against the urging of the spring, and its body then rotated so that its head is transversely located with respect to that space. The device thereby grips between the confronting surfaces of the head and plate these boards of the dock.
