A swash bulkhead is arranged in the fore peak adopted as the first fresh water tank.

Description

technical field [0001] The invention relates to a longline fishing boat, in particular to a longline fishing boat for sailing in far sea navigation areas. Background technique [0002] A longline fishing boat is a fishing boat that uses longline fishing gear to catch tuna, salmon and trout. The longline fishing tackle uses a dry rope, and sets a fishing rope every 50 meters or so. A hook is set on the fishing line, a floating rope is set on the dry rope, and a floating rope is also set at a certain distance. A buoy is attached to the floating rope so that the dry rope is suspended in the water. Usually longline fishing boats are equipped with 2500-3500 hooks, so the dry line is more than 100 kilometers long. Tuna caught by longline vessels is of good quality and is usually cryogenically frozen at temperatures as low as -55°C to -60°C. The price of caught tuna is about 5,000-10,000 US dollars per ton, and the economic value is very high. [0003] Longline fishing boats in...

AI Technical Summary

Problems solved by technology

The layout of longline fishing boats in the prior art is unreasonable, the operating area is small, and the passage is not smooth enough, resulting in unsmooth operation processes of fishing, sorting, picking, transporting, freezing, processing and storing fish, keeping fish warm and unloading fish, affecting fishing efficiency
