Intuition can be misleading.
Which one will generate better flow / lift
- a jib
with hanks on a stay,
- a jib
set inside an alloy extrusion?
And why do racers use extrusions/jib foils?
Which will create more drag / spoil the flow more:
- a thick spar (like a mast),
- a fine rod run an inch ahead of the sail (stay and hanks jib).
And why was such a rod tested / used on airplanes and why was it abandoned.
Trust intuitions if you want, just do not expect others to follow. Part of physics is counter-intuitive. You only want intuition to form questions. Then you want experiment
and measurements to find answers. Intuition DOES NOT give valid answers.
on aero and hydrodynamics, esp those written by hull
and sail designers. You will learn heaps.
