Hydrodynamic Performance of a Deep-Vee Hull Form Catamaran in Regular Waves

This paper presents the results of experiments carried out to determine the motion/seakeeping behavior of a deep-vee hull form catamaran in regular sea condition. A deep-vee catamaran model for the Newcastle University’s new RV replacing the old RV Bernicia was used for the motion measurements. The experiments were performed in the university’s towing tank. The results obtained were validated using a 3D panel method in frequency domain. A comparison of these results with the motion characteristics of the NPL (National Physical Laboratory) round bilge hullform based catamaran of similar geometrical properties revealed that the deep-vee hull forms possess significantly better seakeeping capabilities than a round bilge hull form.
