coupled to the first and second ends. Each end extends into the open bore
vertical support and rests on at least one apron bladder of an apron
bladder bundle. The at least one apron bladder is contained in the open
bore vertical support and at least one apron bladder is between the end
of the vertical support and the bottom of the body of water. A method of
using the apparatus, comprising providing an apparatus having variable
