Currently, we have two different technology solutions, SWATH control and drag reduction.
SWATH control allows us to make a hull form that is typically hard to control move smoothly and safely at speed. Our forward mounted propellers and digital control system make this possible.
One way to think about this is to consider electronic stability control which helps modern cars stay on the road as they move faster or into slippery conditions. That system uses computers to make decisions about application of brakes to keep the vehicle moving safely.
Drag reduction allows us to reclaim energy usually lost by conventional propulsion, the trail of bubbles you often see behind power boats, and redirect it to reduce our drag. We can actively manage movement of air around our hulls and we do so without pumps, fuel or moving parts. As air is much less dense than water it is desirable to have air around as much of the hull as possible.
One way to think about this is how turbo chargers on car engines use exhaust gas to drive improvement in engine performance. But in that case the exhaust gas drives other moving parts. The improvement in performance is real but it adds mechanical complexity. Our improvement does not increase mechanical complexity.
