sharp edges seems to be the way new boards are going.

sharp edges more grip and can hurt, round gives a softer, loose ride.

It is not a easy question. Generally speaking, sharp rails tracks more and round ones has MORE grip.
Latest designs are using the traditional tucked under edge very thin (not sharp) rails.
The best way to understand how a rail works is thinking about action–reaction, how the water leaves the rail edge, a sharp rail realease the water sooner and has a more grip or not grip behaveaur. A round rail has not a fixed release edge, so it digs in the water easily and have a softer feel, the water often release in a more upward motion so the rail is bluried into the water more.

What is the difference from the ridder side? (e.g. board behavior).

from my understanding, rails don't need to be sharp, only thin.

My north robo has a soft rounded rail, but has decent sized fins for grip.140x41

Sharp rails bounce through chop!
Sharp rails work really good in perfect flat conditions.

Softer rails suck into chop making a softer ride, so you have to rely on your fins for edging.Going from a switch 180 and previously a naish 144 wake the softer rails are a better rail shape for allround conditions.

None of the new formica board concepts we saw being developed in tarifa had sharp rails, they where either rounded or almost square.

FLUID DYNAMICS apparently

@mossi

Lets try, cause it is difficult question.

The sharper edge gives you more power over the kite, you can edge harder for example, therefore it is easier to slow down the kite.

The sharper edge ketches more, (I hope tht this is the right word) that means, the board will be more difficult to turn around.
So the softer edges make more fun for surfing style.

As for jumping it is more a matter of technik, also the size and amount of fins will play an important role. Bigger fins, stronger load, bigger jump, but if you have lots of speed, not so big fins are needed.

A guest said, sharper edges are the future, well I just read in the german Kite Magazin, that very sharp edges were the "future" last year, this year softer edges could make the run.

Hope it helped, Sylt Rider :bye:

I think what we will be seeing in the future is soft rails but very thin.

Easier to edge but not catchy.
