Interesting Hydrodynamic Oddity

[aerohead]

I did some simplified 'pencil-whipping':
1) Same propeller
2) Same motor nacelle
3) 3.15:1 NAVY strut of approximately twice the thickness of the round tubing it replaces is the only variable
4) 7.5-MPH velocity submerged in 59-F water
5) Water density ( rho ) = 1.980874
6) @ 745.7-Watts / horsepower
----------------------------------------------------------------------------------------
By exchanging the tubing for the 'thicker' strut, the electric load is reduced by approximately 160-W / hour, or, 21.3-W / mile.
---------------------------------------------------------------------------------------- The strut data was presented by Chief Aerodynamicist, Walter Korff, Lockheed Aircraft Company, as provided in the book, 'Airplane Design: Aerodynamics', by Edward F. Warner, 1927.

That, and the portability, was what attracted me.

In another life, I'd put it on that canoe transom, add at least one outrigger, then shade the boat under a PV array, and spend day and night on some lake.

My ex-father in law made a redwood canoe in the 1960s that we used to ride on the Willamette River. It's been hanging in the rafters of my son's garage up in Puget Sound for a decade or more.

With an outrigger, one could overnight in it.
