Idea for Bilge Pump requiring no power

There are powered bilge pumps for boats but do not seem to be a passive bilge pump that requires no external power - only forward motion of the boat.  Think of a long hose or tube with one end on the bottom of the boat and the other end is hanging outside the boat.  As the boat moves through the water, the moving water over the end of the tube would suck the water from the bottom out of the boat.  A one-way valve would only allow the water to be sucked out and not into the boat.  This concept is similar to smoke being sucked out of an open car window, when the car is moving.
Possible Start Building Blocks –

• Existing concepts for carburetor venturi, airplane wing lift, vehicle air flow analysis, siphons, snorkels, vacuum cleaners, etc.
