Conventional ships have unlimited freeboard (extra tonnage and vertical size to the main deck) to accommodate the predictable hog and sag,  bow plows and deck wash in elevated sea states. The Hydro-Lance formulates this excess and therefore a lesser tonnage ship may more efficiently and safely accommodate the same mission or application.  Even the house is far above the oceans surface and is mostly rectilinear, though stream lined for aerodynamic air and wind management.  The house is designed and frequently structurally separate (intimately adjoined) to the main structural components allowing for modular construction.  One modest sized 2,000 gross metric ton Hydro-Lance vessel could carry a cargo of perhaps, 1,000 tons (that's a lot of people and baggage), while having a significantly higher interior volume of usable rectilinear space to accommodate passenger comfort,  ball rooms, state rooms, and common spaces.  This is due to the entirely different construction geometry of the Hydro Lance.  With normal speeds of 3-7 times greater than that of conventional vessels, and seven times the fuel economy, many more routes are competed in the same time period that the conventional vessel completes just one trip.  This of course, translates to revenue and economics.
