A novel trailer securing and releasing mechanism for a boat is disclosed to facilitate the process when unloading and releasing a boat into the water as well as loading the boat back on the trailer via securing the boat's eye bolt, or ring. The invention device encompasses a spring- or hydraulically-activated mechanism normally attached to the trailer tongue. The boat loading mechanism operates by movement of a horizontal rod being forced in the direction toward the trailer resulting from contact by the boat ring. This contact and movement of the rod forward results in positioning the boat ring within an open claw-like device and, simultaneously, causes the open claw to slam shut wherein each claw arm lies with the boat ring and thereby affixing the boat to the trailer. As the rod arm is moved back within its housing by the forward motion of the boat the energy of said movement is captured and retained, either by a compression of a spring or of a fluid (gas or liquid) within a hydraulic mechanism. Subsequent disengagement of the boat ring from the claw-like device on the boat trailer results from release of the stored energy within the compressed spring (or fluid) to reverse the direction of movement of the horizontal rod that will result in the simultaneous opening of the claw mechanism and pushing of the rod head against the boat ring to release the boat from the trailer.
