Based of CFD-analysis, conventional SWATH's can have up to 20 % wave resistance on the submerged pontoons in spite of minimal waterplane area. All mass-

displacing, both subsea and in water surface make wave resistance. InSvivia's active screw hull make a positive mass-displacing that minimize the subsea wave resistance to 2-3 %, in contrast to conventional 20 %.
