Abstract: A system for transforming a vessel hull to adjust to changing water conditions, changing the hull configuration to adapt to rough water, shallow water, a different draft or speed. The system transforms the vessel hull from a first configuration to another configuration by selectively pneumatically raising and lowering a plurality of integral sponsons that form the hull within seconds without removing the vessel from the water, even with the vessel underway. The system accommodates a multiplicity of engine designs, such as an outboard motor, a motor in a recessed position, a airboat motor or twin engines. A plurality of pneumatic cylinders that raise and lower the integral sponsons are controlled by a controller such as a PLC (Programmable Logic Control) located at a helm of the vessel.
