Further, a bow thruster 61 is also installed to adjust the course by the front and rear thrusters. , The course can be adjusted more accurately. Further, when the seaweed is cut and the seaweed net is treated with acid at the stern, a large space is formed in front of the bridge 3 and the seaweed transport container 76 is formed.
It is possible to secure a sufficient space for installing and the work space.

In the example shown in FIGS. 14 and 15, a flat surface is usually formed by the nori net scooping member 45 on the front side of the bow deck 24 to form an extension of the bow deck 24. For this reason, the bow deck becomes wider, and the scooping member 45 can be used as a step when getting on and off the ship. Further, with this configuration, the hull 2 can be moved forward to perform seaweed cutting work. That is, during the seaweed cutting operation, by operating the operation cylinder 46 from the driver's seat, the seaweed net scooping member 45 is lowered as shown by the phantom line in FIG. If the seaweed net 101 is moved forward, the seaweed net 101 can be scooped up, and the seaweed cutting operation and the acid treatment operation can be performed while the seaweed is transferred along the guide 4 in the same manner as described above. In this case, it goes without saying that the seaweed reaper 41 is installed in front of the acid treatment tank 77. Also in this configuration, there is an advantage that the seaweed net scooping member 46 can be easily put in and taken out.

In the above embodiment, the nori net scooping member only shows an example in which the tip portion is submerged below the sea surface. However, it is not always necessary to immerse the sea nori net scooping member close to the sea surface. All you have to do is do it.
