Abstract: The instant invention describes a multi-purpose rotational barrier unit and a system of interconnected barrier units which function in multiple environments, including aquatic environments and land-based environments. The multi-purpose rotational barrier unit has a design configuration which provides hydro-dynamic stability in strong currents and high waves and resists roll over. The multi-purpose rotational barrier unit comprises a plurality of equally sized walls interconnected to form side walls and a bottom wall. Connected to the side walls and the bottom wall are two opposing end walls which define a hollow interior portion. The opposing end walls contain one or more rotation members which are constructed and arranged to provide the barrier unit rotational movement which is independent from the movement of other barrier units directly attached to its opposing walls or units which may indirectly be attached as part of a larger barrier wall system.
