Abstract
Abstract Aquatic harvesting apparatus employs a harvesting barge with vertical and horizontal weed cutters and a tunnel extending from the cutting throat through the entire length of the harvesting barge for discharge of the cut weeds into a collection container coupled to the stern. The cut vegetation is not elevated from the water during this procedure. The collection container is paneled with mesh and has a gate which can be opened to receive the weeds and closed to seal the container. The container can be towed to shore or elevated by a crane.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
145 words
A method of harvesting aquatic vegetation comprising the steps of providing a harvest vessel with a through tunnel extending fore and aft and above and below the water line, and with converging wings defining a collection throat, providing a transport and collection barge having flotation means to independently float the barge, said barge having a rigid frame and foraminous walls with a fill opening and gate therefor, coupling the transport and collection barge to the harvest vessel with the fill opening in line with the tunnel and causing relative movement between the vegetation and the harvest vessel to cause compacted vegetation to move in line through the tunnel and into the collection barge without elevating the vegetation from the water and when the collection barge is filled to set it free and connect a second collection barge to the tunnel and repeating the foregoing steps.
