Abstract:
1. A method of emptying liquid from a flexible, portable bladder located at the deck of a boat, said bladder, when filled with liquid, increases the weight applied to said deck so that, when said boat is in motion, the weight of the bladder increases the wake generated by said boat, comprising providing a portable bladder that is substantially liquid impermeable, said bladder having a port formed in an upper surface thereof and a sleeve surrounding said port, said sleeve being movable between a closed position in which it seals said port from the egress of liquid and an open position in which it permits the flow of liquid to and from said bladder, and has a mouth on an upper surface thereof, said mouth being of sufficient size as to permit the ingress and egress of a submersible pump of a capacity of at least 360 gallons per hour into and from said bladder, supplying liquid to said bladder through said sleeve in open position so that the weight of said bladder is increased, locating a submersible pump within said bladder through said sleeve and said bladder port, and activating said submersible pump to evacuate liquid from said bladder when said boat is back at its dock on or on its way back to the dock.
