Latest attempt at modeling the Sea Siren, my research jetmarine. First time I've tried a  modeler other than tS, but as good a modeler as it is, it really wasn't getting me anywhere. This is in Hex, and entirely without booleans. After this, I may go back into tS and finish the  old Sea Siren, if what I learned in Hexagon can apply there. I don't really know if tS 6.6 can handle mesh surfaces as well as Hex. :)
