A boat situated on a boat trailer is fitted with a launching rope, attached at one end to a bow eye on the boat and at another end to an eye bolt attached to the rear of the trailer. The rope is supported between its ends by one or more rope retention guides that are situated adjacent to obstacles on the trailer, notably the keel support rollers, that might otherwise interfere with the rope when the boat is launched. To launch the boat, the launching rope is secured to the bow eye and the eye bolt and the trailer is backed down a boat launching ramp to a point at which the bow of the boat is at the waters edge, at which point the winch cable and safety chain securing the boat to the trailer are detached. The boat may undergo spontaneous premature launch at this point, but if not, the trailer is backed farther into the water, allowing the boat to float free as the trailer enters deeper water. The trailer is then pulled up the ramp to a point at which the boat, tethered to the trailer by the launching rope, reaches the beach. The rope is then released from the eye bolt and secured relative to the beach while the trailer is parked. The rope retention guides are made of spring steel wire, formed with a heart-shaped head having a notch that grips the rope, and a long shank to position the head above and to fasten the device onto the frame of the trailer below.
