either lengthen the fronts or shorten the back lines. basic trigonometry. if you think of a Y as part of a triangle you can figure out what length the lines would need to be if you know how high up the split is and how wide the kite is.
So new question. why would North or Naish do this on a kite with 5 lines? They have for several years and the Y should have nothing to do with how the kite flags since it flags to a true 5th line.
I find it hard to believe they do it just for the cleanliness factor. Maybe it really does improve rigidity/stability? I'm really curious if it only does this for some kites or if it would for ALL kites assuming the split is in the correct spot for the given size kite.

In the surf it's no comparism...self landing and un-inverting without assistance are a must. See the last bit of the "strapless" surf Vid elsewhere here: when the guy grabs a leader and lands his kite on a dime. Once you get that wired you won't want y lines, look at the smile cover his face when he nails it.

I fly kites with both types.
On a Y type the 5th is very clean as it travels through the Y split and doesn't tangle much. Also unwinding and sorting the lines is easier since you sort only 4 lines to Y split and then 5 lines from Y to the kite.
On a V type the 5th line likes to wrap around one of the front lines and can be a bit of work to untangle after emergency release. Also you need to sort 5 lines from bar to kite ... .
As for why kite manufacturers make the high Y . . . because they can. The high Y will pinch in a few more pounds than a V, so there's a performance worry when swapping Y and V bars, some kites won't mind it some will. Which kook proof pigtail is best, knot on rear lines or knot on front lines? Which kite type is better 4 lines or 5 lines? Hybrid, bow or C? Foil or inflated?
Kite makers are gonna produce these high Y kites, and V kites, both, there's no clear reason why one or the other will dominate the market.
I like the V better because it means I can swap my bar with all my kites and not worry about performance issues if I decide to run 50 meter extensions.
2014 - Two years later, I just did a head-to-head test of Y vs V-lines.
I recently got a good deal on a used kite. It came with an older 4-line Slingshot bar with a Y configuration. The Y was located about 5 meters from the bar.
So I decided to try it on my new SS Compstick bar, which is a V configuration. The kite flew well on both bars. Y or V, it didn't make a difference that I can feel.
I don't buy kites with Y-lines. That's why I don't choose North or Naish. V-lines seem to work better for everything: For self landings, self launches, hot launches, re-launches, setup, inversions, and tangled lines too.
