Abstract: This float is for commercial fishing trollers and is adjustable so that the same float, after adjustment, may be used with a starboard or port sheer line or a straight line of a multiple line, trolling system. The float element is a relatively long, tall, and thin prism or parallelepiped having desired rigidity and density - the latter to cause it to float high in water. When in use with a fishing, trolling line, it floats with its thin dimension horizontal, thus standing vertical on one of its narrow side surfaces. A bottom plate is connected with the float. In a first embodiment, four holes extend through said plate, with a pair thereof at each end portion thereof, one of each pair toward the center crosswise considered and the others of both pairs toward the same side. An end hook for pivotally mounting an end portion of a rod is detachably connected to a selected hole at each end portion of the float. A center pivot support is mounted on said plate.
