An unmanned seismic vessel system can include a hull system configured to provide buoyancy and a storage apparatus configured for storing one or more seismic nodes, each seismic node having at least one seismic sensor configured to acquire seismic data. A deployment system can be configured for deploying the seismic nodes from the storage apparatus to the water column, where the seismic data are responsive to a seismic wavefield, with a controller configured to operate the deployment system so that the seismic nodes are automatically deployed in a seismic array.

A line hauler on a fish tender vessel is mounted to a port or starboard quarter location of a deck of the vessel. A loop of floating line is wrapped around the line hauler, extends toward the bow of the vessel to a pulley mounted on a respective port or starboard side, then extends down to the sea, then extends on the surface of the sea adjacent the respective port or starboard side to at least the location where the line hauler is mounted to the deck, and then extends from the surface of the sea back to the line hauler. The loop of line moves in a circle when the line hauler pulls on the line. Lead lines are connected to the line. Fishing vessels attached to the lead lines are pulled alongside the respective port or starboard side of the vessel when the line hauler pulls the line.

A line hauling device such as a windlass is disclosed for marine craft. The device has a support, a drum held on the support and rotatable with respect to the support, a motor for selectably driving rotation of the drum in a forward (hauling) direction and a reverse (paying out) direction, and a line laying mechanism for laying the line onto the drum. The drum is adapted to store the line on the drum. When operated in the forward direction, the line-laying mechanism lays the line onto the drum in a first series of turns. On completion of the first series of turns the line-laying mechanism lays the line in a second series of turns overlying the first series of turns. The line-laying mechanism includes a carriage which is driven reciprocally with respect to the drum by rotation of the drum.

An unmanned surface vehicle for underwater investigation that is free from negative effect of a thruster is provided. A position control system for an unmanned surface vehicle includes: at least one mooring device fixed on the ground; a wire fed and wound from the mooring device; an unmanned surface vehicle connected at the tip end of the wire; and at least one rudder equipped on the unmanned surface vehicle, wherein the mooring device includes a mooring device control device for controlling the feeding and winding of the wire, and a rudder control device for drive-controlling the rudder, the mooring device control device and the rudder control device control the position of the unmanned surface vehicle to reach the target.
