Abstract
Abstract A launching and recovery process for top-of-vehicle transported watercraft in which the watercraft always remains correct side up and which is a true one man operation, even for heavier watercraft. The process is accomplished by means of a relatively short length primary dolly located under the watercraft (that is removed only when the watercraft is floated) and a removable transom dolly. Both dollies are used in conjunction with simple tracks and a single winch. The primary dolly provides a means for ground transport of the watercraft and a means for transporting the watercraft up and down a marine launching ramp. This transport can be either manual or aided by the winch previously mentioned.
