Hey,
Even surfers have long questioned the design logic of pointy noses.
Kiters are like sheep.
Monkey see, monkey do.
lol.
Seriously, is there any performance value from having sharp-nosed kiteboards ?
Nope, can't think of any.
Maybe round noses have better feng shui.
The pointy nose gives the shapers something to line up when setting the fins.
A rounded nose can broach when dropping into a wave if you have too much weight on the front foot.
Boogie boarders are not scared of a rounded nose( sorry that only applies to surfing)
Get a custom board and you can have it shaped how you want it.
Not shore how feng shui works with fiberglass and foam
Been thinking the same thing as tobes for more than a decade.
Don't kid yaself sharp noses are anything other than fashion.
Do pop-out mass produced boards have a shaper lining up the razor sharp nose?
20c piece radius is as sharp as is needed. Back in the day I had a couple of surfboards made up and insisted on a 20c radius. Enough point to do the job but not enough to act as a tri-fin shishkebab.
"One less sharp thing to impale yourself on" Ditto for any swimmers popping up unexpectedly.
