Two Log Pontoon hydrodynamics, ventilation & wake characteristics at various speeds

My endeavor to catalog and video typical hydrodynamics seen in Pontoon Operation. Benefits:
1. Why BIG FOOT gearcases exist
2. Why Ventilation in turns occurs
3. Why Performance Strakes, Specialized Nose Cones and Spray shields vary, along with Underdeck Skins. It will also illustrate that a mere 5 mph difference is quite a difference!
This first video installment is:
(2) two-log Pontoon Boat operation. Video endeavors to show 0 mph, 5 mph, 10 mph, 15 mph & 20 mph shots, with detailed speed variations that focus on cone design, cone spray shield, and motor pod design. (Test vehicle was a 20ft pontoon boat with 25inch logs, no Performance Strakes, No Underbelly "WaveTamer" skin, a pretty common pontoon design in 2011) Our next video installments will show two-log pontoons with WaveTamer and Performance Strakes, and even later a triple-log tri-toon operation, and how they vary in spray and turbulence.
We hope that the audience will observe and recognize that pontoons, unlike V-Hull boats, squeeze the water and spray inward. This causes a great deal of turbulence. So a motor must reach down deeper into the water to escape the aerated water, or it is forced to ventilate in the aeration. Moreover, higher speeds above 15mph begin to benefit from lifting strakes and underbelly skin. Even there, we'll endeavor to show the differences in design, cause & effect between strakes and WaveTamer underbelly skin.
