There are many types of fishing boats, the most common ones are rubber boats and assault boats, but these have a weakness that is easy to break. Choosing fishing boats made of aluminum alloy materials can avoid such problems, especially in terms of strength and durability. Aluminum alloy fishing boats can use 5083 aluminum sheet, 5086 aluminum sheet, 5052 aluminum sheet, 6061 aluminum alloy, etc. Among them, 0.25-inch thick 5086-H32 aluminum alloy is the most popular material in fishing boat manufacturing, providing a perfect balance of strength, durability and corrosion resistance.

· Small boats usually use lighter and lower-cost 5052 or 6061 aluminum alloys, assembled by rivet structure. This structure is simple and low-cost, suitable for applications that do not require high strength.

· Large fishing boats use stronger 5086 aluminum alloy and adopt a fully welded structure, which can provide higher strength and fatigue resistance. 5086 aluminum sheet has a wide range of thicknesses to meet the needs of different parts of the hull. Although it is more expensive, it is a more economical choice in the long run due to its durability and long life.

· 6061 or 6063 aluminum alloy extrusions are used for structural and decorative parts such as keels, keels, gunwales and wave guardrails.

Marine grade aluminum sheet specifications for fishing boats:

Common models of fishing boats:

5083 aluminum sheet: widely used in the hull, deck, cabin structure and other parts of fishing boats that need to be in contact with seawater for a long time and bear greater stress.

5086 aluminum sheet: similar to 5083 aluminum sheet, commonly used in the bottom sheet, side sheet, keel and other parts of fishing boats, especially those key structural parts that are directly in contact with water.

5052 aluminum sheet: suitable for non-load-bearing parts such as the internal structure, hatch, internal bracket of the ship, or fishing boats in freshwater environments.

6061-T6 aluminum profile: commonly used in the support structure, frame, keel and keel sheet of the hull.

6063 aluminum alloy: commonly used for decorative and appearance parts such as gunwale, wave fence, etc.

Fishing boat aluminum sheet thickness

The thickness of aluminum sheets for fishing boats varies according to the size and structure of the boat:

Small fishing boats: usually use 3mm to 5mm thick aluminum sheets.

Medium and large fishing boats: Use 5mm to 10mm aluminum sheets. Thicker aluminum sheets may be used for the bottom of the hull and the side sheets to enhance impact resistance.

Features of aluminum sheets for fishing boats

1.Strong durability: The strong characteristics of aluminum alloy make it less susceptible to damage from external impacts, and it will not break or leak as easily as rubber boats.

2.Corrosion resistance: Aluminum alloy is particularly suitable for long-term contact with water, especially seawater environment, and can maintain excellent condition for a long time.

3.Lightweight: The lightweight characteristics of aluminum alloy not only help to increase the speed of the boat, but also make it easier to carry and transport fishing boats.

4.Easy maintenance: Aluminum alloy boats are not easy to rust, and even after being damaged, repairs are relatively simple, reducing maintenance costs.

5.Easy processing: Aluminum alloy has good processing performance and can manufacture complex hull structures through cutting, stamping, welding and other processes, which is suitable for various ship design requirements.

6.Environmental protection: Aluminum alloy is a recyclable material with relatively small burden on the environment.

7.High value retention rate: Aluminum alloy materials can be reused repeatedly as a metal material;
