The AVB system is a versatile tool; use it to reduce vessel slamming, or to make subtle adjustments to LCG for dynamic trim control.
Professional crews of high-speed craft operate in some of the toughest conditions imaginable, and can spend many hours at a time assaulted by torturous sea conditions. Despite this, the performance level required of tactical craft and their crews is incredibly high, and crucially this requirement is not lessened when they are working in sub-optimal conditions. These crews do not get to leave a task until the weather improves, or abandon the chase out of concern for long-term spinal health.
The AVB system not only protects these crews from injury, it also allows for a more versatile and capable force. Stabilising the boat provides a better firing platform when necessary, and gives a performance edge for high-speed interceptor craft over their target vessels.
"The AVB system on our Arctic 24 works flawlessly to provide a stable boat in rough seas, improved boat handling, reduced crew fatigue, and increased comfort."

“Having a ballast system is vital when heading into a rough sea and head wind, to keep the bow of the boat in connection with the sea surface, whilst maintaining speed when responding to a call out. It provides a more capable lifeboat, giving a safer, more comfortable ride for the crew and survivors at higher speeds in heavy weather.”

SEARCH & RESCUE
We're proud that our Anti-shock Variable Ballast system is fitted on hundreds of search and rescue craft, and has helped to save countless lives, from the North Sea to the Eastern Mediterranean.
By definition, these craft are often heading out in conditions that are incredibly dangerous. Using an AVB system not only allows these crews to reach casualties faster by punching through the waves, lowering the bow also grants much greater visibility, which is vital when attempting to locate a person in the water.
Even once the casualties are onboard, a stable boat allows for a far more comfortable journey to shore, especially for those who may already be in need of medical attention.
An issue faced by operators of passenger vessels, whether as thrill rides or crew transfers, is that the total number and combined weight of passengers greatly affects the performance of the boat. This ever-changing variable can be challenging to balance- the UK's Marine Accident Investigation Branch has been forced to issue statements warning operators of the far too frequent injuries reported by passengers, and vessel insurers have drastically curtailed the permitted speed for many tour RIBs.
Using an AVB system instead allows the helm to take control of their LCG, providing a safer and more comfortable ride for their passengers. This not only improves the experience for their customers, but reducing the risk of injury also reduces the risk of litigation or injury claims, and demonstrates best-practice by the company in protecting those on board.
“Having this system is a game-changer, our crew has so much more confidence going on call with it. We once had to go out without the system in service, and it was like losing a crew member.”

"Speed is king, and a bow ballast tank can allow higher speeds in rough waters. Fill the ballast tank in head seas and there is a noticeable reduction in pitching, which allows higher speeds. In following seas, the tank is emptied, restoring buoyancy to reduce the chance of submerging the bow.”

Much like passenger boats, variable payload vessels carrying cargo or equipment are equally susceptible to the shifting of LCG. Impacts large enough to injure passengers can be just as likely to damage sensitive equipment or instruments, or even the vessel itself. Using an AVB system, cargo vessels can safely deliver their payloads from A to B, then compensate for lighter payloads on the return journey.
The rise of unmanned vessels does not diminish the need for stability. These incredibly expensive Unmanned Surface Vehicles (USV's) can often carry correspondingly expensive and delicate surveying and monitoring equipment, which will need to be protected from impact. Whilst current real-world use is limited, they will doubtlessly be ubiquitous in the future of offshore energy, farming, transport, and rescue.
