Product Overview
The AL390 aluminum open boat is an ideal entry-level vessel for leisure cruising, recreational fishing and daily water use. With overall dimensions 3.9×1.7×0.65m, it comfortably carries 4–6 people and perfectly matches 20–30HP outboard motors. Compact size, shallow draft and solid all-welded structure make it the best choice for personal and family water entertainment.
Key Dimensions & Configuration
- Overall Size: 3.9 × 1.7 × 0.65 m
- Passenger Capacity: 4–6 persons
- Recommended Power: 20–30 HP outboard engine
- Hull Material: 5052 / 5083 marine grade aluminum alloy
- Hull Type: Fully welded open boat, shallow draft design
Premium Marine Aluminum Construction
Built with high-strength marine aluminum alloy and full welding technology, the hull is lightweight, rigid and impact-resistant. Unlike fiberglass boats, it will not crack or delaminate after collision. Natural anti-corrosion performance ensures long service life in freshwater and coastal waters, with minimal daily maintenance required.
Excellent Navigation & Practicality
Thanks to its shallow draft design, the AL390 can easily navigate lakes, rivers, narrow waterways and shallow shore areas without grounding. The open layout provides broad vision and ample deck space, perfect for family trips, friends gathering and wild fishing. It runs smoothly with 20–30HP engines, offering stable speed and great fuel efficiency.
Easy Transport & Beginner Friendly
Lightweight overall structure allows easy launching, landing and transportation by several adults. Simple operation design is friendly for new boat users. No complicated assembly, ready for fun on the water anytime.
Best Value for Money
Designed for entry-level users with practical and cost-effective concept. Reliable quality, low maintenance cost and multi-scene applicability make the AL390 a cost-effective aluminum open boat for personal leisure, fishing and daily short-distance water transport.
Conclusion
Welding of aluminum alloy ship hulls is a systematic engineering task involving the intersection of metallurgy, mechanics, and thermal processing. In practical production, the appropriate process (MIG, TIG, or FSW) should be selected based on the hull structure type, plate thickness, and service conditions, and the welding procedures must be strictly followed. By optimizing parameters such as welding current, preheat temperature, interpass temperature, and shielding gas composition, defects like porosity, distortion, and joint softening can be effectively controlled, resulting in aluminum ships that are both lightweight and durable.
