Equipped with a complete bottom trawl system, this commercial aluminum fishing vessel features heavy-duty hydraulic trawl winches, net reels and dedicated hangers for smooth trawl deployment and retrieval. Multiple fish storage compartments are available with customizable temperature settings: insulated chilled cabins ranging from 0°C to 4°C and deep-freeze cabins between -25°C and -60°C. An independent fresh water tank and circulating water system are also installed to support long-duration offshore fishing trips.

The self-draining and anti-slip deck design simplifies post-operation cleaning after fishing harvests. The fully enclosed weatherproof wheelhouse features panoramic windows to guarantee all-round visibility during navigation. The onboard living layout prioritizes crew comfort and safety, with full perimeter safety railings fitted across the working deck. Engine room facilities include automatic bilge pumps, fixed fire suppression systems and mounting bases for safety equipment such as life rafts. Clients can customize the diesel main engine, auxiliary generators and large-capacity fuel tanks to match their expected sailing endurance.

Product Superiority

1. The aluminum bottom trawler net fishing vessel has excellent low-temperature toughness. It will not undergo brittle fracture in seawater at -20°C and can absorb collision impact force, avoiding hull cracking when hitting rocks or underwater obstacles.

2. Ultra-low fuel consumption, and the lightweight aluminum hull reduces resistance, resulting in very low daily usage costs.

3. The maintenance cost is extremely low. No rust prevention maintenance is required, and the service life lasts up to 25 years.

4. It has stable trawling performance, fast turnover speed, and spacious and efficient cargo compartments and storage space, with extremely high fishing efficiency.

5. It has safety and environmental advantages: excellent collision safety performance, using non-magnetic and flame-retardant, environmentally friendly and recyclable materials.

6. Flexible customization and global adaptability.

7. It has high stability during trawling operations, and is not prone to rolling.

8. It supports single or double bottom trawling mode, enabling automatic deployment and retraction of the net equipment, reducing manual operation.

9. It can be optionally equipped with a flybridge; integrated with Foxconn fish finder, echo sounder, GPS, AIS, VHF satellite communication, radar and net depth monitoring system to achieve precise underwater fishing positioning.

Main Application Scenarios

1. Coastal bottom trawling for shrimp, flatfish, squid and crabs, suitable for short 1–3 day nearshore fishing voyages
2. Offshore deep-sea trawling targeting cod, halibut and sea crabs; equipped with refrigerated holds to support 5–10 consecutive days of open-water operation
3. Estuarine and reef fishing grounds with mixed salt and fresh water

4. High-value fisheries for live lobsters, prawns and crabs supplied to premium seafood markets
5. Fisheries resource survey vessel fitted with hydrological monitoring devices for marine stock assessment
6. Auxiliary patrol and management boat for local fisheries and coast regulatory authorities
7. Compatible with multiple fishing gears including trawl nets, gill nets and cage traps

FAQ

Q: Is aluminum hull repair complicated after reef collision damage?

A: Aluminum welding technology is widely mature across most regional shipyards. Local repairs can be carried out conveniently at relatively low cost, much more economical than replacing fiberglass hull sections.

Q: What is the maximum offshore endurance of this trawler?

A: Sailing range depends on fuel tank and cold storage configuration. Standard coastal vessels support continuous navigation for 3 to 5 days. Models fitted with extended fuel tanks and deep-freeze cabins can achieve 10 to 14 days of non-stop offshore fishing without refueling.

Q: Can your company support custom configurations such as hull length, trawling system, and refrigeration capacity?

A: We offer complete customization services. The hull length range is 6 meters to 50 meters; according to customer and local fishing requirements as well as port regulations, the load of the trawling winch, the temperature and volume of the refrigeration room, the number of cargo holds, the size of the live water tank, and navigation equipment can be adjusted.

Q: How long is the production cycle of this aluminum-bottomed bottom trawler?

A: Small coastal trawlers (6–18 meters): approximately 35 working days; medium-sized ocean-going trawlers (18–30 meters): 60–90 days; large ocean-going trawlers (over 30 meters): 120–180 days. The specific time depends on the complexity of the facility configuration.

Q: Can you provide door-to-door transportation or overseas launching guidance?

A: We offer various delivery options: small vessels are transported by heavy trucks on land, while large ships are transported by deck cargo shipping; our professional ship engineering team can go overseas to assist with launching, equipment debugging, and crew operation training.
