... then there's the "utility hatch" located centrally inside of the sleeping compartment.  During inclement weather you simply open the hatch and "jig" for dinner without leaving the comfort of your shelter!  It's kind of like a floating ice house.  It's also a convenient "escape hatch" should a park ranger come by to check on your paperwork, etc.

Their next model allegedly features a helium balloon contraption that is covered with soft solar panel fabric.  You release it skyward on sunny days and it gathers enough solar energy to run your in-boat lighting system as well as any electronic gadgetry you may have brought with you.  It doubles as a radio transmission and reception antenna.

Rumor has it they are toying with a pull-behind "launching/landing dock" for a small fleet of reconnaissance drones.  Never again worry about whether that next campsite is already occupied!  Simply launch your drone & find out.  Power your drones with solar energy that you collect yourself!

Now if you could only be sure the danged floating tent could actually be steered to that open campsite!!
