I'm not sure this test answers the same question for my fixed 2 blade prop that is mounted in the dead wood in a cutaway in front of our rudder. With this configuration we can align the prop with the hull theoretically 'hiding' it from being a real drag.
Do you know of any studies that might have been done on fixed 2 blade props with this configuration?
Thanks in advance, as always.
Assuming you have fairly constant wind, course and so on, GPS speed seems pretty accurate?
