The hull size is the most important parameter among all design elements to determine the navigation quality of a R.I.B. (Rigid Infl atable Boat).
Because of the tubular absence and the transom moved backwards till the stern end, all the ZAR models are equipped with a quite longer hull than all the other traditional R.I.B. of the same overall length.
As you can see in the below plans, all ZAR models must be compared with quite longer R.I.B. to find the same hull length.
Moreover, the absence of the tubular element in the bow (International patent) has made it possible to build hulls with a very deep V and to obtain models which perform very well under any sailing conditions.
The lateral tunnels (another patent) increase the lift at high speed, thus sailing is more comfortable under any sea conditions.
