February 22, 2007 Recreational vehicles will come in many different forms in the future as a raft of developing enabling technologies spawn new categories of technologically-enhanced ground, water and aircraft – not only are these traditional categories splintering, but there are new variations of toys for big boys, some of which will develop their own categories – craft like the part boat, part sled, part ground-effect Tupelov aerosan, the Bionic Dolphin and Sea-Breacher, the SeaPhantom, a host of recreational submarines such as Deep Flight, the amphibious Quadski and the list just goes on and on of new RVs that break out their own category.
