Hull
The watertight body of a boat.
How to sign
Use Dominant curved-C; palm faces the base. The base or passive hand is Non-dominant horizontal flat-B, palm down: hull base. Set the flat-B boat in neutral space, bow away from the signer. Hold curved-C at the bow-side outer edge. Trace the outside shell from bow to stern just above and around the flat-B base. Stop at the stern-side outer edge; retain the hull base for the next sign. Establish the boat with a horizontal flat-B hand. With the other hand in a curved-C, trace the outside shell from bow to stern and finish at the flat-B boat base.
