The improved stinger system includes a pivotal, compression hitch, a stinger coupling, and one or more stinger sections. The hitch pivotally connects the front end of the coupling to the rear end of the vessel and establishes below the pivotal connection a compression joint between the coupling and the vessel. Pivot means carried on the rear end of the stinger coupling pivotally connect the uppermost stinger section for pivotal motion about a generally horizontal axis extending through the stinger coupling. The pivot means can be selectively and vertically adjustable along the rear end of the coupling to change the pipe's radius of curvature dependent on the desired exit angle of the pipe from the stinger system into the body of water. At least the stinger coupling carries horizontal, pipe-engaging support rollers and lateral, pipe-restraining rollers. The horizontal support rollers can be selectively and vertically adjustable to provide for predetermined radii of curvature for the moving pipeline.
