Abstract

A fairing is disclosed for mounting upon a cylindrical member which is deployed underwater. The fairing has a generally wedge shaped body (4) which tapers from front to rear. The body (4) is mounted upon the cylindrical member (8) through a collar (6, 6') in which the member is received. The fairing is thus mounted with its front face adjacent the cylindrical member so that the assembly of the fairing body and the member can together form a teardrop shape. The collar permits the fairing to weathervane, rotating about the cylindrical member, to align itself with a current.
