Claim:
1. A fairing device for the reduction of vortex-induced vibrations or motions and reduction of drag about a substantially cylindrical element immersed in a fluid medium, comprising; a mainly cylindrical element, a fairing rotatably mounted about the mainly cylindrical element, the fairing comprising a shell with a mainly cylindrical cross sectional shape with an outer diameter (D) following the outer diameter of said cylindrical element from an upward stagnation point of 0 degrees to at least +/−90 degree locations, which at said +/−90 degree locations continue as two fin-like portions in an aft direction and defining a chord length (C), wherein the fin-like portions are convexly curved aft of the +/−90 degree locations thus tapering towards each other defining a tail end opening gap less than a fairing standoff height.
