ABSTRACT:
The present invention is a floatation apparatus with a self-deploying mast for use in a marine towing operation. The invention includes a mast assembly. The mast assembly comprises a shaft adapted to pivotally mount in a storage position on the floatation apparatus, a pair of masts mounted on the shaft forming a structure with front and back sides and dividing the masts into a top section above the shaft and a bottom section below the shaft, pairs of arms and legs projecting perpendicularly from the front of the top section of the masts and from the back of the bottom section of the masts, respectively, a crosspiece connecting the arms to each other and another crosspiece connecting the legs to each other. The distribution of the weight of the mast assembly results in the mass of the bottom section being greater than the mass of the top section such that when the buoy is placed in the water, the mast assembly pivots to a desired operational position and is held there by the force of the water against the front of the mast assembly. When the floatation system is returned to the deck of the vessel, the mast assembly is pivoted back to its storage position. The floatation apparatus in the preferred embodiment is a tailbuoy.
