Good point!
I will try to remember.
the term foil is often used and confused.
I fall into the trap so many times.
Exactly why you call a "foil" kite what it is, RAM AIR, and no confusion possible!
As well as these days with SO many H2o foils available almost also need to stipulate board type,, kite,surf,SUP,Wake,SAIL board,ECT...
