Andrew,
I use the flukes and kite effect to my advantage when anchoring.
I always anchor from the stern while slowly moving forward. I release
the anchor, and allow the rode to go through my hands like a kite
string. (I always wear gloves when sailing.) I provide a little bit of
resistance. The anchor goes pretty much straight down. The floating
rode follows it until the anchor hits bottom, at which point some of the
line floats to the surface and is not taut.
At this point I hold the line firmly. The line enters the water at a 45
degree angle or less. The anchor sets -- I can feel it in my hands. I
cleat off the line, and the boat stops moving. I move the line forward,
turning the boat under my feet.
You are right that the floating all rope road never hits the bottom
before the anchor, and never fouls the flukes -- it is always pulled by
the shank and is always positioned between the boat and the shank.
