The hull of RM, RW, RD, RC and RV line is the result of an innovative design study called R. I. H. C., which stands for Rancraft Innovating Hull Concept. 
It is an exclusive technology by Rancraft Yachts which delivers very high performances, which translate into reduced power consumption and ease navigation. These benefits are due to the particular shape of the hull and above all to the particular cross step of the hull that ensures less friction resistance even at low speed planing time ensuring reduced maintenance and lower speed planing. The proper functioning of the principle of action of these steps is guaranteed by a sufficient and regular ventilation through side air intakes prohibiting the sudden increase of friction resistance in partial areas. All this translates into a safe, comfortable and performing navigation.
