A High-Density Polyethylene (HDPE) marine boom includes an elongated generally cylindrical shell including inner and outer layers formed from HDPE with the same formulation. The inner layer includes at least 2% carbon black by mass and the outer layer does not include carbon black. The outer layer includes a colorant with ultraviolet stabilizers and the inner layer does not include the colorant. The inner layer is thicker than the outer layer and they have been coextruded to form a unitary body. First and second caps, each including a radially extending circumferential annular flange, formed from the same material as the outer layer are fusion welded to the shell across the full thickness and around a full circumference of first ends and second ends of the shell and form a watertight seal. A floatation billet is in the shell. A lug plate for the HDPE marine boom is also disclosed.
