The displacement Deep-V catamaran concept was developed in Newcastle University(UNEW) through development of thesystematic Deep-V catamaran series. One of the most important Deep-V catamaran launched to date is Newcastle University’s ownmulti-purpose research vessel, The Princess Royal. The vessel was launched in 2011 and enhanced the Deep-V catamaran conceptfurther with the successful adoption of a novel anti-slamming bulbous bow and tunnel stern for improved efficiency. It was howeveridentified that the vessel has substantial amount of dynamic trim that limited the visibility of the captain. The dynamic trim also increasedthe wave-making resistance thereby preventing the vessel from attaining its maximum speed in certain sea states. This paper thereforepresents the application of devices such as Trim Tabs, Interceptors, Transom Wedges and Integrated Transom Wedges-Tabs to controlthe dynamic trim and improvement of fuel eficiency of the vessel. All of these energy saving devices were fitted into a model for testsin Newcastle University’s Towing Tank. Model test verification confirmed that the optimum appendage was the interceptors, theyproduced a 5 % power saving and 1.2 degree trim reduction at 15 knots, and investigations of full scale trials will be scheduled withand without application of device to compare the improvement of performance.
