Abstract

A system for reducing drag and/or vortex induced vibration of a structure, the system comprising a multiple finned device comprising from at least one long fin having a first average height and at least one short fin having a second average height, wherein the height is a radial distance extending outwardly from the structure, and wherein the first average height is at least 10% larger than the second average height.
