The wheel 64 comes in contact with the bottom of the water at the tip of the cutting conveyor 5, and the distance between the bottom of the cutting and the tip of the cutting conveyor 5 is always kept constant regardless of the tilt angle of the cutting conveyor 5. Since the cutting position (length) of the root portion of the aquatic plant 49 can be made constant, uneven cutting can be eliminated.

  The aquatic plant removal work boat 1 is configured as described above, and the propulsion motors 22 and 23 attached to the hulls 2 and 3 of the catamaran 4 have their screws 65 and 66 directed in a predetermined direction with a predetermined output. By driving with, it is possible to move forward and backward, turn, and further to the side.

  That is, when the left and right propulsion motors 22 and 23 are rotated forward with the same output, the aquatic plant removal work ship 1 moves straight forward and reverses the left and right propulsion motors 22 and 23 with the same output. When going straight forward and rotating one of the propulsion motors 22 and 23 with an output larger than that of the other, they turn toward the higher output side.

  Further, as shown in FIG. 8, the aquatic plant removal work ship 1 changes the postures of the propulsion motors 22 and 23 in directions opposite to each other in the direction orthogonal to the hulls 2 and 3, and If you rotate 22 and 23 in opposite directions, you can proceed in the right side direction.

  Thus, in the aquatic plant removal work ship 1, the propulsion motors 22 and 23 are arranged at the outer central portions of the hulls 2 and 3, and the propulsion motors 22 and 23 are orthogonal to the hulls 2 and 3. The position of the catamaran 4 can be moved in the lateral direction by rotating the propulsion motors 22 and 23 in the opposite directions to each other. Therefore, the cutting operation and movement along the wall surface can be performed satisfactorily, and the operation operation of the aquatic plant removing work ship 1 can be facilitated.
