Abstract

An information system for trawler operation includes a radio link between the bridge or other vessel control station and each of a plurality of fishing devices on the vessel. Each fishing device has a radio transmitter that sends signals from which the vessel operator can determine for such fishing device, such variables as line speed, line tension, line payout and the like. Suitable sensing mechanisms are provided together with appropriate electrical circuitry.

Claims

1. A trawling line information communication system comprising a fishing device mounted on the deck of a trawling vessel, a sensor for detecting the delivery winding speed of the line of said fishing device, a sensor for detecting tension applied to said line, a transmitter for transmitting line information detected by each of said sensors, a receiver mounted on the operator side of the trawling vessel for receiving and demodulating a transmitted signal from said transmitter, an indication part controlled by a demodulated signal from said receiver for indicating the length of the delivery and winding of said fishing line, a means for informing a vessel operator of the delivery and winding speed of the fishing line, a line tension indicating part controlled by the demodulated signal from said receiver for bar-indicating the tension of the fishing line, and a timer means starting to operate when a fish is caught by said fishing device.
