Why FINVAL boats are known for durability
1. Marine-grade 5083 H111 aluminum
* FINVAL uses marine-grade 5083 H111 aluminum, one of the most respected aluminum alloys in commercial marine construction.
2. Heavy-gauge hull construction
* Hull plating is typically 3 mm to 4 mm thick, depending on model size. (.157 inch)
* Boats over 5.5 meters (18 ft) use a 4 mm bottom structure, providing exceptional impact resistance and rigidity.
3. Fully welded structure
* FINVAL boats are fully welded rather than riveted.
* Reinforced stringers, bulkheads, keel sections, and chine structures distribute loads throughout the hull and reduce long-term fatigue.
