The term you're looking for is "venturi". Suction is created by the flow of water (or air) past the venturi and it draws water (or air) through it. It's the principle used in carburetors. > The problem with using them on a kayak is you need to be moving > very fast for them to work.

However, they have buoyant hulls with large trapped air spaces for floatation and no real cockpit. I don't know how well they would work on a closed kayak with a flooded cockpit. -- Regards Brian *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
