How to sign

Use Dominant upright 1-hand or vertical flat-B. The base or passive hand is Non-dominant horizontal flat-B, palm down: boat base. Set the boat. Start the upright hand at the center of the hull. Raise it vertically in one straight path. Hold it upright and still above the hull as the mast. From the center of the established boat, raise a vertical 1-hand or upright flat-B hand. Keep it straight and stationary after the upward placement.
