Description
Boat Air Bags are parachute-type underwater lifting bags specifically engineered for raising sunken vessels, hull sections, or marine structures. Their unique open-bottom, single-point lift design provides a stable, vertical ascent during underwater recovery. Constructed from heavy-duty, reinforced fabric and fitted with marine-grade hardware, these air bags offer exceptional strength, durability, and resistance to abrasion and UV exposure. Ideal for both shallow and deep-water operations, they are widely used in commercial diving, shipwreck salvage, and marine construction projects. Each unit includes a pressure relief valve for safety and comes in a variety of lift capacities ranging from 100 kg to 50 tons.
