-5- Wave-making drag is not very dependent on hull length beyond a certain min prismatic hull ratio.



should read :

-5- Wave-making drag on cats, in an absolute sense, is not very dependent on hull length beyond a certain min prismatic hull ratio.

In this case the wetted surface drag is by far the most dominant factor and it is this aspects that will favour shorter extreme lightweight hulls over longer lightweight hulls.
