Barnacles are of economic consequence, as they often attach themselves to synthetic structures, sometimes to the structure's detriment. Particularly in the case of ships, they are classified as fouling organisms. The amount and size of barnacles that cover ships can negatively impact their efficiency by causing hydrodynamic drag. Fortunately, this is not a problem for boats on inland waterways, as barnacles are exclusively marine. Uzun et al. (2020) provide a simplified approach for estimating the effect of real barnacle settlement in nature on the resistance and effective power of the ship.
