Boat Salvage Lift Bag - Reliable Buoyancy, Durable Construction, Quick Setup
The Boat Lift Helper, also known as Cylindrical Underwater Lift Bags, is a professional-grade buoyancy aid designed to safely lift, support, or salvage vessels and underwater structures. Made from heavy-duty, tear-resistant coated fabrics, these lift bags provide reliable buoyant force in both shallow and deep-water conditions.
Key Advantages
- Cylindrical design minimizes sway and rotational forces during ascent
- Heavy-duty, tear-resistant coated fabrics for durability
- Reinforced D-rings and straps for secure attachment
- High-visibility panels for diver monitoring
- Quick deployment and controlled ascent
Case Study
In 2023, a marine salvage company in Miami used 12 Boat Lift Helper units to recover a 12-ton fishing vessel that had sunk at a marina entrance. The cylindrical lift bags were deployed by a three-diver team in less than 30 minutes, resulting in a 40% time reduction compared to traditional square-style lift bags.
