  • Patent number: 4211513
    Abstract: This invention is a releasable pulley device that can be readily attached to the center rear of a boat trailer and through which the tow-in line for a boat is threaded. As the boat is winched in to the rear of the trailer an alignment of the prow with the center rear of the trailer is effected. The pulley device is released from its seating and rides free on the line as the boat is fully winched on to the trailer. This enables the dry loading of a boat from rough water as a one-man operation.
