Large Boat Kit
When the system detects extensive flooding, it automatically activates.
The buoyancy bags inflate in under 60 seconds, delivering 10,000 newtons of lift or more, depending on configuration. This helps keep the vessel afloat, stabilizing it, and gives valuable time to respond.
The system is installed internally within the vessel and consists of a CO2 tank, water sensor, buoyancy bags, and connecting hoses that distribute air evenly between the bags. The components work together as a single system to ensure rapid and controlled buoyancy.
The Large Boat Kit is available in multiple configurations, tailored to the vessel’s size and weight.
Designed and manufactured in Norway
Antisink is manufactured in Norway and meets all required approvals, with quality assured at every stage of the production process.
Certified and robust
All Antisink products are CE certified and comply with relevant international maritime safety standards. They are compact, impact resistant, waterproof and flame retardant, and can also be manually activated if required.
With a focus on the environment
All components are reusable or recyclable. If Antisink is activated, the system only needs to be repacked before it can be used again.
The only part that needs to be replaced is the water sensor, while the CO2 cylinder can be refilled. The system is easy to install and prepare using the included installation guide.
If in doubt, we recommend contacting us or your local dealer.
