1. An apparatus, comprising:
an elongated buoyant flotation tube having a length and a longitudinal axis;
a plurality of fence sections attached to said flotation tube spaced apart around a circumference of said flotation tube and extending radially outwardly therefrom, said fence sections spanning substantially the entirety of said length of said flotation tube, each of said fence sections comprising:
a plurality of fence posts attached to said flotation tube and extending radially outwardly therefrom, and
fence connecting members spanning the space between said fence posts,
said flotation tube having sufficient buoyancy to support said flotation tube and said fence sections at the surface of a waterbody, and wherein when said flotation tube and fence sections are positioned on said waterbody surface at least one of said fence sections extends a sufficient distance radially outward from said flotation tube and above said waterbody surface so as to create an obstacle to vessel passage over said flotation tube, the direction of vessel movement toward said flotation tube defining an approach side of said flotation tube, with the opposite side of said flotation tube defining a protected side.
