Partially submerged, buoyant portable marine fence has netting material attached to series of float-supported longitudinally spaced upright fence poles which extend from bottom of water to above the surface of water. Floats are attached to each pole at the low water elevation on each pole. When horizontal wind or water forces are exerted upon fence, poles pivot about detachable ballasts located at the base of each pole.
