DEFINITION

Classification: 43/9.1

Trawl:

(under subclass 7) Subject matter wherein the open fabric of twine or equivalent material, i.e., net, is shaped to form a large, flattened bag and is adapted to be towed behind a boat-like vessel at a desired depth, e.g., along the bottom of a body of water, etc., or wherein structure closely allied to such a net is provided.

(1) Note. A device which digs into the earth along the bottom of the body of water in order to dislodge fish is not proper for this class.
