Experimental measurements of the complex motion of a suspended axisymmetric floating body in regular and near-focused waves

▸ Experimental measurements are reported for an axisymmetric wave energy converter float subjected to regular and near-focused waves. ▸ The mechanical system, incident wave conditions and response in a 2D vertical plane are detailed. ▸ Supplementary files are included to facilitate comparison to numerical simulations. ▸ For particular regular wave conditions, linear responses are reported. ▸ More complex multi-mode motions are observed in large amplitude, near-focused wave groups.
