Something that only would be possible in a large hub. 'or take-off perhaps hydro-skis or a retractable step should be incorporated,as a fixed step would spoil aerodynamics. ' Good idea!reply @RP1'I think the hull would need a step, and might porpoise, as the shape isn't really like a planing hull.'Had a bit of trouble finding out what porpoise is, but now I understand what you mean.It is logical from a boat-engineering view, but it would be less efficient from a airodynamic view. Maybe some sort of 'flap' that extends while taking-off, could do the trick.reply @OrionblamblamLooks speedy <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />Is it a CG-image or an actual model?reply @elmayerleAny chance you coul find it( private collection piece?) or a small sketch? Was it a official project from some firm or a engineers fantasy?cheersRob</blockquote>
