In every case I've ever seen, you have two straps, connected to two shafts, which are geared to move in unison (typically through a chain mechanism).

You are going to have a lot of weight on a relatively wide strap. This results in high friction, so if you lift the strap from one side only the boat is going to tilt, until gravity takes over at an unpredictable time when it shifts suddenly.
