A biography and a documentary are in the works to tell more than we can in this limited amount of space.  Spence always conjured, "If you  fly on a float, you  missed the boat."  The picture above well illustrates the buoyancy of the near perfect hull.  The unchallenged feature of this near perfect hull is the patented bow door and nose gear bumper for docking 
Along with the hull is the adaptability of the design to various power plants.  Shown is the venerable Continental Tiara with reversible, controllable pitch by Hartzell.  Brochures, info kits are $10.00,  Plans are $300.00.  There is over 550 square feet of paper in a set of blueprints, representing more than 3000 hours of drafting over a forty year period .
