The rod protector includes a plurality of openings through which a fishing rod may be at least partially inserted and easily removed. The shield includes an anti-slip or other safety surface to provide improved safety on the fishing vessel.

An outrigger assembly includes an outrigger tube with a longitudinal axis. A swivel ring is disposed on the outrigger tube. The swivel ring is rotatable with respect to the outrigger tube about the longitudinal axis. The swivel ring has a line guide for guiding an outrigger rigging line in a direction along the longitudinal axis.

The present disclosure belongs to the technical field of fishing operation equipment in fishery, and relates to a net hauler for a trawler. The net hauler includes two rope drums, a drum rotation shaft is disposed on each rope drum and includes a first rotation shaft and a second rotation shaft, a drum is disposed on the first rotation shaft, a cylindrical housing is disposed between two ends of the first rotation shaft and the second rotation shaft, a pivot is disposed on the cylindrical housing. The present disclosure has advantages of changing a net hauling speed and improving a fishing efficiency.

The present disclosure provides a trawler with a fishing and conveying device and a fishing method, and belongs to the technical field of trawlers. The trawler of the present disclosure includes a hull structure and two fishing devices, wherein the fishing device includes a first rotary rod, a second rotary rod, a fixing frame and a fish suction mechanism, the first rotary rod is hinged at the bow of the hull structure, a fishing net is connected on the first rotary rod, the second rotary rod is hinged at the stern of the hull structure. The present disclosure is capable of realizing continuous fishing and directly conveying the fish onto the trawler, and thus is simple to operate.

This publication relates to a system and a method for hauling fish gear, such as longlines, gillnets or demersal seine nets, into a fishing vessel (10) and collecting and transporting catch (12) to a working station, using a hatch (16) in a part of a hull exposed to the sea and arranged in a water line region (27) of the vessel (10); a vertical well (18) for receipt of at least pa rt of the catch through the hatch (16); a transport device for transporting the catch to the deck; and with means for bringing the catch to flow towards the transport device. The transport device (24,25) used is arranged in a shaft (19), separated from the well (18), and a closeable opening or hatch (23) is arranged in a wall or bulkhead (21) between the well (18) and the shaft (19) 127 and with devices for opening and closing the opening or hatch (23), and a bottom (22) in the shaft (19).

Arrangement and method for manoeuvring a vessel that is towing a load. The vessel has a block at the aft end, over which at least one tow line extends. The block is moveable transverse to the longitudinal axis or longitudinally of the vessel. The position of the moveable block defines a point of attack for a tension force from the tow line. An autopilot is coupled to an actuator moving said block, in order to change the moment of force about a rotation point of the vessel. The autopilot has a calculation unit, which detects the tension force (W1, W2) and calculates the moment of force on the vessel. The autopilot can thus use a change in said moment of force to manoeuvre the vessel.

A spreading device for trawl fishing, seismic survey operations or other water activities where it is desirable to keep distance between two sides of a towed device is provided, the spreading device having at least one part comprising two or more foils, where each foil has a front surface and a rear surface, the surfaces each being defined by two edges and two side limitations, in use being front and rear edges, an upper and lower side limitations connected to respective upper and lower frames, where at least one foil is stationary and where one or more sections of another foil is pivotably connected to the another foil, such that the section may be moved from a position where the surface of the section is flush with the surface of the another foil, to a position where the surface is out of plane with the surface of the another foil.

The present invention provides a catamaran centralized-transportation fishing ship and a control method, which relate to the technical field of fishing of fishing ships. The catamaran centralized-transportation fishing ship has the fishing assembly and the concave chamber for centralized transportation of fish bodies, which can simultaneously have two functions of fishing and centralized transportation, and has a wide application range. Compared with existing fishing ships for fishing operations, the fishing ship can place the caught fish bodies in the concave chamber, so that the fish bodies can be in original water quality during a transfer process, and thus a survival rate of the fish bodies is increased. Meanwhile, setting of the limiting mechanism can prevent the fish bodies from escaping and increase a fishing amount of a single fishing operation.
