Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an algae cutting work boat for cutting algae that grow in water by an algae cutter installed in front of a hull.

[0002]

2. Description of the Related Art In the above-mentioned work boats, since cut algae are loaded on the hull to proceed with the work, when the loading amount reaches a predetermined amount, the work is temporarily interrupted, and then the cargo is transferred to another carrier. , Start working again.

[0003]
