A keel attached to a central body of trolling spreader bar is configurable with a plurality of fishing lures as an assembly to mimic a small school of fish. The keel is angled to urge the lure assembly continually to one side or the other from what would be the normal straight line of travel of a trolling vessel. By attaching an angled keel directly to the lure/spreader bar one is able to easily set lines behind the vessel at varying angles and distances which greatly increase the width of the full trolling lure spread.
