Hydrofoil-supported catamarans (Hysucats) have emerged in the last two decades as competitors against monohulls in terms of efficiency in high-speed planing regimes. Nonetheless, according to the literature, they have not been compared experimentally. In this work, a monohull, a catamaran and a Hysucat hull were compared experimentally in order to evaluate the geometry with the best hydrodynamic behavior. The hulls were towed along a body of water with a test bench and variables such as drag, trim angle, wetted area, wetted keel length, and sinkage were measured both with sensors, installed in the boat and in the test bench, and multimedia data. These geometries had the same length, width, draft, submerged volume, and weight distribution. The equations derived by Savitsky were used as a precursor for the experimental design and for a deeper understanding of the planing phenomena. It was found that the Hysucat and the catamaran boats present up to 50% higher drag in planing speeds than the monohull, basically due to their much higher wetted area and lower trim angle. However, some potential alternatives for improving the hydrodynamic efficiency of the catamaran and the Hysucat are proposed.
