Anyone who orbits at an uncontrolled field when I am there will be hunted down to discuss airmanship too, regardless of whether they are an instructor or not
Surely it is good airmanship to do an aerial inspection of your proposed landing site? I would also suggest that it is irresponsible to just turn up and land without any form of inspection.
For float flying we consider a full 360deg inspection (minimum) is essential for proper assessment, as cables, wires and underwater obstacles may not be visible into sun.
