Self-righting system SR22001000

Product overview
The Automatic self-righting system is designed for lifeboats, workboats and unmanned surface vessels (USVs). The system provides automatic, sensor-triggered inflation to restore a capsized vessel to an upright position quickly and reliably. It is engineered for rapid response in emergency capsize situations and for marine durability.

How it works
The system uses inflatable buoyancy units placed to shift the vessel's center of buoyancy and weight on inflation, enabling righting without external assistance. On-board sensors detect capsize (activation angle >120°) and trigger immediate inflation via pre-charged CO2 cylinders; typical recovery time is around 30 seconds.

Key features

• Automatic activation via onboard sensors (sensor-triggered inflation, trigger >120°)
• Rapid inflation to minimize time spent capsized (typ. ≤30 s)
• Durable Hypalon inflatable units suitable for harsh marine environments
• Self-righting capability without external/manual intervention
• Model SR22001000, Spec OD1000x2200

Benefits

• Enhanced safety for crew and passengers through automatic righting
• Reduced damage, exposure and downtime after capsize
• Compact installation for stern-mounted small boats and USVs
• Low maintenance and long service life for primary structure (consumables excluded)

Additional product notes
The automatic version price shown on the product page is USD 5,500 (FOB Qingdao). A manually-operated (hand) type is available at a lower price. All prices quoted FOB Qingdao.
