Abstract
A semiautomatic visual trailing guide to assist a steerer in backing and loading trailers such as boat, recreational vehicle, or utility type. The device generally consists of a self-boosting self-latching mechanism capable of pivoting an element between a horizontal position and a vertical position while employing a force to hold in either position. The device is mounted on the rear most center of a trailer and will rotate the element to a visual position after being initially urged towards that position. The element is kept vertical by tension from the self-boosting self-latching mechanism until a forward force such as a boat, jet ski, or car push on the element and the element collapses to a horizontal position.
