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.

Described herein are methods and systems to dampen oscillations of a payload coupled to a tether of a winch system arranged on an unmanned aerial vehicle (UAV). For example, the UAV's control system may dampen the oscillations by causing the UAV to switch to a forward flight mode in which movement of the UAV results in drag on the payload, thereby damping the oscillations. In another example, the control system may cause the UAV to reduce an extent flight stabilization along at least one dimension, thereby resulting in damping of the detected oscillations due to energy dissipation during movement of the UAV along the dimension. In this way, the control system could select and carry out one or more such techniques, and could do so during retraction and/or deployment of the tether.

Described herein is a hoist fleet system including a head block and a guide fleet assembly. The head block includes a plurality sheaves having more than one diameter. The guide fleet assembly can be arranged proximate the head block such that an array of lift lines can be routed through the plurality of sheaves of the head block into the guide fleet assembly. The guide fleet assembly further includes a plurality of guide sheaves and a plurality of plates. The plurality of plates is configured to house the plurality of guide sheaves. The plurality of guide sheaves is positioned substantially orthogonal to the head block. The plurality of plates is further arranged such that the plurality of guide sheaves is arranged on more than one plane. The plurality of guide sheaves is configured to reduce the spacing of the lift lines.

A crawl space winch system including a base plate; a winch box carried by said base plate; a winch mechanism disposed in said winch box and having a cable extending out of an opening in a front side of said winch box for attaching to an item; a winch drive shaft extending through a sidewall of said winch box and being operatively associated with said winch mechanism for retracting said cable; and, a primary anchor opening disposed in a generally central portion of said base plate for receiving a portion of a primary anchor to secure said base plate to the ground, and wherein said primary anchor provides a pivot point around which said base plate rotates.
