Operating Instructions
Once fully assembled, the Ship Gravity Swing Model operates through a kinetic balance system. To activate the motion:

- Gently turn the gravity hammer (the weighted pendulum at the bottom).
- The oars of the boat will begin to swing, creating a continuous, soothing motion.
The model is designed for kinetic motion and does not require batteries.
