Behold the ReconCraft Riverine Shallow Draft Vessel (RSDV), which features a uniquely designed hull-shape that essentially allows it to slice through four inches of water like butter through a knife:



So how is this possible? The unique design helps funnel water into its water-jet intake allowing it to propell right off the surface with extremely minimal draw. The hull is made of reinforced aluminum and is painted with proprietary "Hardkor" coating that supposedly increases hull strength while reducing friction on contact points. This allows it to top out at a very speedy 45 knots, which translates to 51.8 miles per hour.
