With this setup I wonder why even have the motor on the ship? It's using an extension cord to get power to the ship so it can pull on the wire guides, but you might as well just have put the engine pulling the wire on the shore and have a "dumb" platform in place of the boat.
- AdamJacobMuller 4y agoThe wire would need to be parallel to the water at just above or below it and would always obstruct other traffic. This arrangement allows the wire to fall onto the seabed so ships can easily pass in front of and behind the ship, given reasonable clearances.

If on the shore the cables would either need incredible tension or incredible power to overcome the friction of the seafloor. By having the winch part on the boat, the boat can pull itself along without having to overcome the friction in the cable between itself and the shore. This way also has the advantage that the cables can be easily rested on the sea floor to allow other ships to pass by.
