Restyling and not just at first glance it seems that creators 'Katran – 460' repeated corpus 'Rainbow-41' in the glass just one to one. In many respects this is true, and yet in the original draft had a number of changes that may seem minor, but nonetheless, pursue a definite goal. By itself, the concept of lines and basic control of the theoretical dimensions of the drawing by the same. We recall that Yuri Zimin developed its project in the years when the experiments with 'nonstandard' contours remain largely the prerogative of samodelschikov. Contours of the type 'kafedral' attracted designer as its driving characteristics and high technology the production of affordable housing from the ground while domestic craftsmen material – plywood. Formally 'kafedral' can be attributed to the tri-, although side sponsons are relatively small compared with the actual housing and markedly elevated relative to the keel line – rather it is developed bilge spray. One important element of contours 'Rainbow-41' was quite wide (which occupied almost half the width of the Corps School) Bottom moderate compared to the actual hull deadrise (7.5 to 18 ).

Since the power of today's outboards are not limited to modest quantities in the 20-30 hp, designers 'Qatran' much of its Sause, sacrificing buoyancy in favor of more benign course with excitement. Become narrower ski protrudes from the bottom of the high 'step', the side faces which prevent slippage Corps in sharp turns. Housing some 'grown up' in length (primarily due to the speakers crinolines), slightly increased height of the board.
