ABSTRACT:
Flotation spars are detachably connected along the length of an oil containment curtain to insure the verticality of a floating containment boom. Spaced tubular sleeves extend vertically along one side of each band. The sleeves are so configured as to pivotally or hingedly mount the flotation spar to the curtain in such a manner as to permit a free pivotal action of the sleeve and spar with respect to the face of the curtain. The flotation spar is also secured to the sleeve by a pair of locking tabs that extend upwardly from the top edge of the sleeve. A cap slides over the top end of the spar and fixes the locking tabs between the cap and spar wall.
