Boat trailers; Boat ramps;


When loading a boat from the water to a trailer, it is preferable to align as fast and as straight as possible. This will minimize the amount of time the boat ramp is being occupied and will also allow for a safer more balanced load while trailering to the next destination. Designing a new boat alignment device, this study took the boat alignment process off the boat ramp and out of the water to dry land in the the staging area. Compared with traditional ways of aligning a boat on a trailer, this new boat alignment device shows advantages in reduced required steps to align a boat and time required occupying the boat ramp. This dry land alignment process was achieved through mechanical manipulation of the boat hull through motorized linear actuated lead screws and a scissor jack.

Through Single Minute Exchange of Dies (SMED) analysis and a detailed comparison it was found the device eliminates extra steps on the boat ramp and simplifies the boat alignment procedure. The machine is in the prototyping phase and on track to be completed in the next coming year.
