Henyrk, The Photo is of Scott Price with a production float equipped Kasperwing, I believe it is the last unit of over three hundred that Cascade Ultralights produced. The video is of Steve Groddruck testing floats for the first time. Steve can be seen standing on the floats in an attempt to stay dry and gain sufficient angle of attack for take off. The initial tests revealed that the spray from the floats rapidly damaged the wooden prop and soaked the pilot, a series of spray skirts were fabricated to eliminate the water problems. Scott and Steve's solution was a full span, float to float skirt, I suggested to using airfoil ribs in the fabric, the result was a system that completely eliminated prop damage and kept the pilot dry. Additional benefits were that the Kasperwing would now take off in a shorter run than it land based counterpart and the weight of the floats being offset by the added lift of the increased lifting surface. We believe the short water take off run to be a function of the compressed air between the floats lifting the airplane in the same manner as Alexander Lippisch's water skimming, ground effect machines. The large open area at the front of the KW float skirt directing and compressing airflow to provide lift when in contact or close proximity to the waters surface. The only downside to the float system was a reduction in airspeed, this is of course is to be expected for float equipped planes. As I stated before, the OEM floats should be lengthened approximately a foot aft of the step to provide more floatation ,stability and prevent aft tip over which one pilot experienced while inspecting his sparkplug.
