System to sink and float buoys
First Claim
1. A water sport course having a plurality of guide buoys controlled by a system which alternately sinks the buoys below the surface and raises the buoys to the water surface, comprising:
- the control system which includes a submarine for each buoy;
each said submarine which includes a housing containing an inflatable bladder expandable and contractible within a water chamber, water vent holes, and ballast weight;
each said submarine being connected to an associated buoy by a tether line;
an air distribution system which includes a network of tubing to supply and remove air from the bladders of each submarine;
wherein the supplied to and from the bladders is controlled from a single point; and
wherein supplying air to the bladders acts to inflate the bladders thereby expelling water from the submarines and causing the buoys to rise to the surface and removing air from the bladders acts to deflate the bladders thereby allowing water to enter the submarines causing the buoys to sink below the surface.

Abstract
Submarine (6) devices consisting of cavity to hold sand and an inflatable air bladder (10) are located beneath and connected to floating buoys (2). The weight of the sand when put inside the cavity is enough to sink buoy (2) until submarine (6) sits on the bottom of a lake or river. When bladders (10) are inflated by air supplied by an air compressor or a portable air tank, and distributed through a network of polyethylene tubing. They create enough buoyancy to offset the downward pull of the sand, thus allowing the buoys (2) to float back to the surface of the water.

5. A control system which alternately sinks the buoys below the surface and raises the buoys to the water surface engagable with a water sports apparatus in which this system includes at least one buoy, comprising:
-
a submarine for each buoy; each said submarine which includes a housing containing an inflatable bladder expandable and contractible within a water chamber, water vent holes, and ballast weight; each said submarine being connected to an associated buoy by a tether line; an air distribution system which includes a network of tubing to supply and remove air from the bladders of each submarine; wherein the supplied to and from the bladders is controlled from a single point; and wherein supplying air to the bladders acts to inflate the bladders thereby expelling water from the submarines and causing the buoys to rise to the surface and removing air from the bladders acts to deflate the bladders thereby allowing water to enter the submarines causing the buoys to sink below the surface.
